Have you ever had a time when you have thought and
thought and thought and nary a comment would appear? One
worth taking up space with. . .while Greg Burns is screaming
for more space for items he and his staff feel need imparting
to the membership?
At this just-past-the-halfway-mark of the current
administrative year, the Executive Board is on top of the income and out-go of cash and will be studying various problems
and answers to those problems (for presentation to the
membership) that will face the Society i n the next few years.
The Entertainment Committee has already forgotten the
trauma of putting on the Shrimp Peel and has begun working
on the Spring events. The initial response to the Arkansasand
Utah field trips is good, and the geology faculties of the area
universities are trying to determine who their outstanding
student is. The Continuing Education Committee has a fine
program slated for the remainder of the year; and the Library
Committee, with help from the Auxiliary, continues to work at
the Main Library. Peggy Rice hasa finegroupof speakers lined
up. Lots of reasons to be a member and to participate.
If you want to help - give a yell; and why don't you ask
your professional peers if they are members?
GEOLOGIST FOR HIRE!
Your Houston Geological Society Placement Committee
has resume's available on numerous geologists seeking
employment. Most are recent graduates with great potential
waiting to be developed; others have varying amounts of
experience as a geologist or in closely allied fields such as well
logging. Give us a try. You may find just what you are looking
for and save yourself the placement agency fee as lagniappe.

The field trip went generally well and our misfortunes
were minor (no sour cream for the beef stroganoff - running
out of gas on the way home). The rain held off and the sun
managed to shine a little. The geology was spectacular,
interesting, intriguing, even confusing, so our wits were
challenged several times a day. We did hike a goodly amount,
up and down as well as laterally, but that wasthe point of the
trip, after all, since one sometimes feels that the art of doing
field work on foot is a vanishing one. Our leader, Dr. Dwight
Deal, did a great job of organizing and leading the field portion
of our trip, pointing out the many biological, zoological, and
social facets of the country we hiked through as well as the
geology. All of our vehicles performed like they were supposed
to, particularly the venerable school bus as it ground it's way
into and out of Fresno Canyon. The scenery, waterfalls, ledges,
cliff faces, and all, were magnificent. I extend hearty thanks to
the people who helped me make this field trip.

NOON
Sket~h
W. H. (Bill) Roberts was
born in Moorestown, New
Jersey. He attended Amherst
College, Wyoming
University, and finally the
Colorado School of Mines,
where he received a degree
in geological engineering
under F. M. Van Tuyl and
completed extra work in
geophysics
under
Carl
Heiland.
During World War II he
controlled air traffic for the
FAA and served as an
engineer in the Maritime
Service. For the next 12 years Bill worked up and down the
Rocky Mountains from Albuquerque to Edmonton for Union of
California, National Petroleum Corp. Ltd., and Gulf Oil. He has
spent 27 years with Gulf, including 8 years at the research
center in Pittsburgh. He has been in Houston for 13 years with
the Houston Technical Services Center of Gulf Research and
Development Company.
With Gulfs blessing, Bill has been devoting some time to
AAPGcommittee work. He organized the Short Course and the
Research Symposium on "Problems of Petroleum Migration"
for ,the annual meeting in Oklahoma City in April 1978. In that
symposium he presented one of the key papers: "The Design
and Function of Oil and Gas Traps." That paper, which
introduced a number of new concepts in support of the
anticlinal theory, was later presented
to several local
geological societies including the HGS, where it won the
annual best-paper award for 1977-78. For the 1979 AAPG
meeting in Houston, he was chairman of the AAPGTechnical
Program Committee.
In September 1979, Bill gave a paper on "The Use of
Temperature in Petroleum Exploration" at Symposium II,
Unconventional Methods of Exploration for Petroleum and
Natural Gas, held in Dallas.
STATFJORD FIELD (NORWEGIAN
NORTH SEA}FROM CONCEPTION TO PRODUCTION (Abstract)
Statfjord Field, located on the international boundary
between Norway and the United Kingdom, has more than 3
billion bbl of recoverable oil and 3 trillion cu ft of associated
natural gas. It is the largestfield discovered todate in the North
Sea. Mobil is the operator for a consortium of companies
including two State and nine private oil companies.
The water depth is near 500 ft and so-called :'100-year
storms" with sustained winds.of 105 knots and 100-ft seas
seem to occur at least 'once a year, creating very difficult
operating conditions.
The field is being developed with three large, gravity-base,
concrete platforms capable of combined production of
600,000 to 700,000 bbl of oil per day plus 700 million cu ft of
natural gas. The platforms will also provide for water injection
plus gas injection initially until a sales outlet for the gas is
developed.
The Statfjord "A" platform, with daily production of
300,000 bbl per day, is the largest offshore producing facility
in the world.
Oil transportation
is accomplished
through large,
articulating loading platforms located near the production
platforms.
COMMON FACTORS AMONG ATYPICAL
FIELDS (Abstract)
Certain factors are functionally relevant to the occurrence
of typical as well as atypical oil and gas fields. Consideration of
such factors leads us to regard the distinction between typical
and atypical fields as a matter of degree. For purposes of
discussion, however, attention is focused on the more clearly
atypical fields.
In a study of the workings of oil and gas fields, it is quite
possible to reach the right conclusions for the wrong reasons.
In other words, we may observe an apparent relationship
between the presence of oil or gas and certain geological 'or
geochemical factors without determining the true causality of
that relationship (which could involve other vital factors
unperceived). Thus, our conclusions can be founded on mere
coincidence; and once reached, those conclusions maycarry a
lot of conceptual momentum.
At this stage in our knowledge of petroleum origin we
probably stand to learn more from the "atypical" than from the
"typicaL" Why? Because some of our tacit assumptions are
challenged. The atypical situation forces us to answer new

employed by universities and governments, I estimate the
current
U.S. geologic population
at around 45,000,
comparable to, but somewhat higher than, other recent
estimates. About 60 percent, or an estimated 27,300, are
employed in the petroleum industry; about 5 percent of the
industry total are with service companies; and the balance is
nearly equally divided among major companies, non-major
companies, and independents and consultants. Approximately
8,000 geologists are on U.S. university faculties. State
geological surveys and other state governmental agencies
employ about 2,200 full-time geologists; federal governmental
agencies employ an estimated 2,700 geological professionals,
with nearly half working for the U.S. Geological Survey. Some
2,500 geologists are estimated to be engaged in mining and
related activities, and about 2,500 are in a variety of other
employment, chiefly with private-sector consulting firms.
Overall geologic population has increased on the average
of about 2,000 annually during the past 7 years and about
3,000 per year. during the past 3 years, according to my
estimates. With 'such an increasing rate, supply in excess of
demand is likely in the near term.
Regardless of whether these estimates are precise, it is
clear and obvious that the major portion of the geologic
profession is involved, either directly or indirectly, in oil and
gas activity, chiefly exploration. If a prorated portion of the
geologic population on U.S. faculties and in governmental
agencies is added to the number employed in the petroleum
industry, something on the order of 75 percent of the
professionally errfployed geologic population is involved,
directly or indirectly, in oil and gas activities. This has
historically been the case, and it has certainly been the case
. during the past decade. Further, the major growth over the
next several years will continue to be related to oil and gas
exploratory activities. Thus, the future of the geologic
profession over at least the next score of years will be rather
inescapably tied to future levels of activity in conventional oil
and gas exploration, perhaps even more so than historically.
A couple of basic questions are thus posed: (1 )What isthe
outlook, over time, of domestic oil and gas drilling? and (2) .Is
there a predictable numerical relationship of the number of
geologists employed and the level of exploratory drilling?
If our current knowledge of the U.S. geologic population
must be estimated, historical data on the number of geologists
and their employment are less certain. We do, however, have
historical data on the number of AAPG members, as well as
current data on employment of members (courtesy of Fred
Dix). As of year-end 1979, some 15,500, o~ 65 percent of the
total AAPG membership of 23,826 (including foreign and
student members), were employed in the U.S. petroleum
industry by companies or as consultants and independents.
Not all are exclusively involved in U.S. exploration, but the vast
majority are. Currently, the relationship of total AAPG
membership to the estimated geologic population directly or
indirectly engaged in U.S. oil and gas exploration is about 1.0
to 1.3. Assuming this ratio has some historical validity, the
historical relationship of NFW's drilled and the number of
geologists
engaged
directly or indirectly in domestic
exploration can be shown (Fig. 1). The correlation seems good
for the post-WW IIupswing (through 1956) and for the current
upswing (1972-80); expectedly, the correlation is meaningless
during the doldrums of 1957-1971, if AAPG membership is
used as an estimation basis. Accordingly, for that period Ihave
simply inferred the exploration population and ignored the
AAPG membership correlation.
GEOLOGIC ACTIVITIES INTO THE
21 ST CENTURY:
WILL THE BOOM BUST AGAIN?
WilLIAM L. FISHER
Bureau of Economic Geology
The University of Texas at Austin
Recently AAPG President Robey Clark remarked
on the apparent irony that
geologists tend to fare well .
when times are tough' for'
many others. My colleague
at The University.of Texas
at Austin, Walt Rostow, an
economic historian, would
immediately
note that
Robey's observation is a
logical and obvious consequence of a Kondratieff
upswing-economic
cycles
brought on by resource
supply shortages. We are
in the fifth such upswing of the past 200 years, each
occasioned by material shortages and rising prices. The earlier
ones involved potatoes, wood, coal, among other things; this
one, as we all know, involves energy-specifically,
conventional oil and gas; and that, in turn, involves the bulk of
professional geologists. But each upswing is followed by. a
downturn when supply and demand return to economic
balance. We saw a geologic downturn in the late 1950's and
1960's, when domestic oil and gas exploration sagged to half
of earlier efforts in the face of declining domestic finding rates,
the discovery of giant fields overseas, and governmental
pricing policies.
But for now domestic eJ.<ploration is back to historical
levels of the middle 1950's and booming, and geologists are
being trained and employed at unprecedent rates.ll)
How long will the trend of the past 7 years persist?
What will be the impact on professional geologists when
the upward trend moderates, stabilizes, or just plain fizzles?
Do we vastly increase the population of employed,
professional geologists over the next decade-and-a-half only
to have demand slacken thereafter?
In short, how will we fare in the next Kondratieff down
swing?
To get some idea of the future, we should look at where we
are now and where we have been. For openers, we do not have
precise data on how many professional geologists there are
and what they do, though recent estimates have been made by
the National Petroleum Council and the American Geological
Institute. On the basis of membership of such professional
organizations as AAPG and estimates of professionals that are
members, along with published accounting of geologists

Figure 1
In the post-WW II upswing an estimated two geolog~srs
were employed, directly or indirectly in exploration, for each
wildcat drilled yearly; by contrast, the current upswing has
involved about four geologists per NFW drilled annually. Such
relationship is consistent with the fact that rate of finding per
NFW in the 1970's was about one-fourth that of the earlier
upswing, but that overall exploration techniques were
improved. Further, a larger percentage of geologists,
especially with major companies, is involved with exploration
outside the U.S.
There are numerous qualifications to the apparent
historical correlation of numbers of U.S. geologists involved
directly or indirectly in exploration and the number of NFW's
drilled, and even more when projected into the future.
Nonetheless, it gives us some rough basis for projecting the
magnitude of the future geologic population, assuming we can
make a reasonable projection of future domestic wildcat
drilling.
We have a finite, but unknown, quantity ot domestic oil
and gas yet to be discovered. Estimates vary, but the average of
several estimates is on the order of 160 billion BOE of
conventional crude and natural gas, or nearly40 percent of the
estimated ultimate, conventionally recoverable base. If these
estimates have any validity, they indicate that the volume of
1
Hounon Geologist Society Bulletin, February 1981
the remaining domestic oil and gas resource base is not a
fundamental constraint over the next 20 years. Even if we find
four times the volume of oil andgasoverthe next20yearsthat
was found from NFW drilling the past decade, an event not too
likely, we would exhaust no more than half of the estimated
remaining resource base. Much more critical than total
volumes yet to be found, in my opinion, is the rate of finding or
volume found per increment of NFW effort. If this rate follows
the trend ofthe past 30 years, it will continue to decline, and,
with accelerated drilling, the rate of decline will increase. It is
assumptions of rate of finding, costs of finding, and value that
econometricians crank into their models. And these models,
again depending upon assumptions, indicate that current
increases in wildcat drilling will continue into the early to
middle 1990's, but thereafter level off and begin to decline.
One can make some different assumptions and change the
pace and timing of the curve, but geologic and resources
realities will not permit a change in the basic shape of the
curve. The curve will peak and eventually decline; differences
are when, not if. This in no way implies that conventional oil
and gas resources will be rapidly approaching depletion, but it
does assume that conventional oil and gas will be
progressively more difficult, and hence progressively more
expensive, to find, and with an eventual loss of some

competitive edge versus the costs of developing other energy
sources.
While the number of geologists involved in the drilling
effort-as well as the pace, rate, and timing of the future
exploratory drilling curve-depends on assumptions, it seems
inevitable that the decline will occur at some point in the
future. And with that decline will also come an obvious
slackening i n the demand for geologists in domestic
exploration, even with likely increased geologic investment
pc?r increment of exploratory activity. For example, we could
see a geologic population directly or indirectly involved in
exploration of 50,000 to 55,000,75 percent greater than now,
in the early to middle 1990's. With a population of that size and
with an annual decline in drilling of 2 percent, 1,100
geologists annually would have to be absorbed by retirement,
by other geologic employment, or, as we saw in the downturn
of the late 1950's and 1960's, by becoming engaged in the
hawking of pots, pans, and real estate, not to mention used
cars.
The age distribution of the current U S . geologic
population, inferred from the age distribution of AAPG
members, is strongly bimodal. One group has a mean age
under 30, another about 55. Forty-five percent of the
population is 50 years or older; 55 percent is 45 or older. Let's
assume a current population of 45,000 geologists, and an
early to middle 1990's population of about 73,000. By the early
to middle 1990's. about 18,000 of the current population will
have reached standard retirement age. Twenty-seven
thousand of the current population would still be engaged, and
the balance of some 46,000 (roughly 4,000 per year) would
have entered the market since 1980. Thus, if a downturn
occurs in the early to middle 1990's. it would impact a
professional group of which more than 8 0 percent would be
under 45 years of age. If a 2-percent decline in demand for
exploration geologists occurs, retirement attrition could barely
soak up half the slack, assuming no new entries into the
profession after the decline begins.
Will there be other sectors of geologic employment
available when the decline in conventional domestic oil and
gas exploration occurs? Much of this depends on when the
inevitable downturn occurs. If it occurs later than the middle
1990's, progressively more of the growth demand in other
sectors will have been met; if it occurs earlier, movement to
other potential growth sectors will be easier. But, in reality,
few other sectors of geologicemployment are asconsuming of
geologic manpower, or in my judgment likely to be in the
future, as conventional domestic oil and gas exploration. Of
those that are, such as hard-mineraland uranium exploration,
none now, nor likely in the next 20 years, will approach the
volumetric significance of oil and gas exploration. An
exception might be vastly increased involvement of U.S.
geologists in oil and gas exploration outside the U.S.
There will, i n coming years, be an ever-increasing
reliance on coal, but coal exploration does not require a
geologic investment comparable to exploration for hard-tofind resources. Synthetic production of oil and gas from coal
and shale will increase significantly; special exploratory
demands will be in finding particular kinds of coal andshale to
meet specific processes. Enhanced recovery of oil, including
tertiary and also infill drilling based on detailed geologic
definition of reservoir heterogeneity, will be an everincreasing effort. The worldwide squeeze on oil supply will
lead to continued modification of national-oil-company
policies in various countries and toan enlarged involvement of

U.S. geologists in overseas exploration. Whether we shall see
densities of drilling overseas comparable to those historically
in the U.S., even in the first part of the 21 st century, depends
on global economics and policies of foreign nations not easy to
judge at this time. As the rather dire positior~the U.S. is
developing relative to critical and strategic mineral
dependency comes into full play, enlarged efforts in U.S.
mineral exploration will occur. Special demands for
groundwater exploration and development will intensify. And,
although probably in decline, conventional oil and gas
exploration will still be a major involvement of professional
geologists, and larger than now. The list could go on. But, will
these areas of demand absorb the supply of geologists when
domestic oil and gas exploration plateaus or declines? M y
guess: some, but not all.
Conclusions
The demand for professional geologists will continue at a
high level for the next decade or so. Volumetrically, the bulkof
the demand will be for conventional oil and gas exploration;
other areas of growth will be exploration for specific coal and
shale resources amenable to specific synthetic processes,
exploration for hard-mineral deposits, enhanced oil recovery,
groundwater exploration and development, among others.
Conventional domestic oil and gas exploration will peak most
likely during the decade of the 1990's. It will romain high, but
will show enough decline to impact seriously geologic
employment. Nonetheless, we will see geologic employment
in the first quarter of the 21 st century some 45 to 65 percent
greater than present.
The intermediate-term, overall outlook for the geologic
profession seems bright. The next Kondratieff downswing,
when others flourish and we languish, is some time yet in the
future. But, along the way, employment adjustments
occasioned by the future of conventional oil and gas
exploration will occur, and will most likely be severe. In the
near term, imbalance i n supply and demand will occur.
In the final analysis, there can be no complete insurance
against employment shocks in a profession such as geology,
so thoroughly tied to resource finding and development, and
hence, to fundamental market forces. We have experienced
ups and downs before, and we most likely will continue to do
so. The U.S., indeed the world, faces a demanding,
monumental challenge in finding and developing sufficient
energy and mineral resources to sustain economic growth and
world stability. The role of geologists is and will continue to be
fundamental. But the mix will change;demand will be more
diverse, and shocks are thus inevitable. Our best, our only real
insurance is, as it always has been, a broadly trained,
competent, and flexible profession.

Department of Interior during the Ford Administration.
My interest in this short paper, as invited by President Baird,
is only to contemplate the long term-into the 21st century.
A n associated, near-term issue of critical importance is the
anticipated supply of newly trained geologists and demands
for their professional expertise. Even with demand running
high in recent years and likely to continue for at least a
decade, the real prospect of a near-term supply in excess of
demand exists.

OLIGOCENE-MIOCENE
The Oligocene-Miocene interval (in particular the
Catahoula Formation) is widely recognized as containing
significant amounts of volcanic detritus (Bailey, 1926,
McBride et al., 1968, Galloway etal., 1977).Thedistribution of
igneous and volcaniclastic rocks is presented in Figure 3 and
Table 3.
Deposition of the volcanogenic sediments i n the
Catahoula interval records the renewal of volcanic activity
within the Gulf Coastal Province. Considerable confusion
exists concerning the usage of Catahoula as a stratigraphic
term. This section deals with the regionally correlative
Catahoula interval as defined by Galloway et al., (1977).
Several detailed papers have described the Catahoula
interval (Bailey, 1926; McBride et al., 1968; and Galloway et
al., 1977). Volcanic detritus is extremely abundant in the
Gueydan Formation, the Catahoula correlative in the Rio
Grande Embayment (Bailey, 1926, and McBride et al., 1968).
Thick sequences of tuffaceous clay, tuff, ash and bentonite
have been reported. The average grain size of volcanic
conglomerates is extremely coarse. Boulders, cobbles and
pebbles composed of trachyte, trachyandesite and rhyolite
porphyry are common. Major constituents of sandstones are
quartz, sanidine, plagioclase feldspar, volcanic rock
fragments, clay clasts, carbonate rock fragments and chert
(McBride et al., 1968). Galloway et al. (1977) found that the
abundance of volcanic rock fragments decreases to the east.
Despite the considerable work that has been done on the
Catahoula, the source of these volcanogenic sediments is
difficult to determine as mid-Tertiary igneous exposures are
not present i n outcrop. Catahoulan igneous rocks have not

PALEOCENE-EOCENE
The lower stages of the Cenozoic denote a period of
relative quiescense during the sporadic history of Gulf Coast
volcanism (Fig. 2 and Table 2). Bentonite is present i n rocks of
Midway and Sabine age at scattered localities (Ross et al.,
1929 and Murray, 1961 ). This is hardly conclusive evidence of
concurrent volcanic activity. It may merely represent the
reworking of fine grained Upper Cretaceous volcanic products.
On the other hand, it may either be an indication of localized
small scale activity, or distinct eruptions in areas outside the
Gulf Coastal Province.
Claiborne and Jackson Stages record an increase in
volcanic detritus (tuff and volcanic rockfragments).This minor
activity foreshadows the burst of volcanism of the Oligocene
and Miocene. Eor-ene sandstones contain volcanic rock
fragments, glass shards, and ash in south central Texas
(Eargle and Foust, 1962, and Chen, 1970). Todd and Folk
(1958) reported that volcanic components i n the Carrizo
Formation increase in abundance to the south. Furthermore
they suggested that the volcanic source lay to the south,
offshore i n the present Gulf of Mexico. Further evidences of
Eocene volcanism have also been reported i n a wide area
ranging from Mississippi to the Veracruz Basin of Mexico
(Table 2).

been encountered in the subsurface, nor is there any
geophysical evidence indicating the existence of buried
volcanic vents. Recent studies suggest that the source of
Catahoulan volcanogenic sediments lay i n the Davis
Mountains, i n and west of Big Bend National Park and in a
poorly known adjacent area i n northern Mexico(McBride et at.,
1968, and Galloway et al., 1977). Bailey (1926) proposed that
source vents were located close to the Gueydan outcrop.
Reexamination of data published i n studies of Catahoula
volcanic deposits leads to the conclusion that large quantities
of the sediment were not derived from such a distant source as
the Davis Mountains.
Thick exposures of coarse conglomerates i n the Gueydan
formation have been reported from Duval and McMullen
Counties, Texas (McBride et al., 1968). Boulders are common;
the coarsest occur i n beds that appear to have been deposited
by volcanic mudflows. Freeman measured boulders that were
40,36, and 25 inches in diameter(McBride et at., 1968). Bailey
( 1 9 2 6 ) reported abundant boulders f r o m fluvial
conglomerates; the largest measured 2 0 x 1 6 x 15 inches.
It is well known that the grain size of fluvial sediments
decreases rapidly downstream. This results from slective
sorting and deposition of coarse particles as flow competance
and channel slope decrease (Leopold, Wolman, and Miller,
1958). Studies of fluvial transport i n active volcanic regions by
Davies and others (1978) documented a reduction i n mean
grain size from 4 m (13 ft.) boulders to 2 mm (.08 in.) detritus
over a distance of 4 0 miles. Walton (1977) noted that detrital
grain size decreased from boulders as coarsest clasts to
cobbles i n less than 11 miles on the aprons of Eocene
volcanoes i n the Davis Mountains.
Boulders and cobbles in the Gueydan formation could not
have been transported i n a single transport cycle from the
Davis Mountains, 300 miles distant (by mudflows or fluvial
transport). It is more likely that the source vents for the
boulders and cobbles lay less than 5 0 miles away, where
eroded remnants have been buried by more recent sediments.
Lack of geophysical evidence indicating the presence of buried
volcanoes is inconclusive. (As was discussed i n the previous
section, Braunstein and McMichael (1976) discovered a

formation sensitivity to different well-bore fluids i n these
rocks. However, other common minerals, particularly goethite,
ankerite, and the zeolites can also increase formation
sensitivity to man-introduced fluids. These minerals should be
identified accurately prior to designing mud and treatment
systems.
IMPLICATIONS
MODERN ANALOGY
It may be difficult to envision the Mississippi Delta region
as one-time including volcanoes. However, the modern Niger
Delta is a good example of deltaic sedimentation flanked b y a n
impressive 13,430 foot volcanic cone, Mount Cameroon
(Figure 4). I n 1922, Mount Cameroon erupted explosively and
distributed volcanic ash over the sediments of the Niger delta.
Lava flowed from lateral vents. Such volcanic activity is a
common occurrence i n the Niger delta region. At least 9
eruptions have been recorded since 1 7 0 0 (MacDonald, 1972).
M t . Cameroon is part of the Cameroon volcanic zone, a
Cenozoic alkalic volcanic region immediately adjacent to the
Benue Trough (Fig. 4). The intimate association of alkalic
volcanism, basin subsidence and deltaic sedimentation makes
the Benue Trough, a modern aulacogen (Hoffman, 1974). an
excellent analogy for the volcanic periods of Gulf Coastal
Province history. Niger deltaic sediments interfinger and
intermix w i t h volcaniclastics and lava flows at the base of M t .
Cameroon. At some future time the Cameroon volcanic zone is
likely to develop into a major rift system (Burkeand Whiteman,
1975). If this were to happen, the volcanic sources would
become buried like many of those i n the GuIf Coastal Province.
The Gulf Coastal Province resembles the geographic
setting of the Benue Trough. It also lies i n a reentrant of a
continental margin. The Mississippi and Rio Grande
Embayments are t w o troughs which extend toward the North
American platform interior, transverse to the trend of the Gulf
Coast Geosyncline. May these t w o features also be classified
as modern aulacogens? The major sources of volcanism i n the
northern Gulf Coastal Province have been associated w i t h
these depressions (Figs. 1-3). In one respect they do not
resemble classical aulacogens. Most aulacogens begin as
If w e are to thinkof the GuIf Coastal Province asa volcanic
region, there are several implications. Local volcanic sources
can greatly influence the geometry of sand bodies and the
intensity and style of diagenesis. Offshore volcanic centers
would have functioned as eastern and southern sources of
sediment i n a basin which is considered to have derived
sediment only from the north and west. Deltas and submarine
fans that may have formed on the flanks of these volcanoesare
potential petroleum reservoirs. They w o u l d thicken
dramatically toward the source and average grain size would
increase rapidly i n that direction. Due to coarse grain size,
original permeability may be high but i t would be greatly
influenced by diagenesis.
Diagenesis is intensified i n volcanic sediments (Davies et
al., 1979). It involves both the loss of original porosity and the
development of secondary dissolution porosity. Dissolution of
chemically unstable glass and high temperature minerals
introduces numerous mobile ions into the pore waters. High
ion concentration increases chemical activities and causes
precipitation of pore filling minerals. The minerals to be
expected i n the pores of volcanic rich sediments are legion,
and include goethite; hematite; ankerite; numerous different
zeolites and clay minerals. Where sandstones have undergone
loss of original permeability, secondary porosity may be
created by dissolution of chemically non-stable grains of
feldspar and volcanic rock fragments.
Sandstone reservoirs i n the vicinity of volcanic centers
w i l l have pore-fill assemblages many times more complex
than average Gulf Coast sandstone bodies. Greatcare mustbe
taken i n the design of drilling and treatment fluids to avoid
serious formation damage. It is important to remember that
the pore-fill minerals do not solely consist of clay minerals.
Clay minerals are indeed of importance i n increasing the

narrow fault-bounded grabens and later become broader
downwarps (Hoffman, 1974). The Mississippi and Rio Grande
Embayments have subsided as broad downwarps throughout
their entire history. Thus the thickness of sediments have
never reached aulacogenic proportions within the continental
platform. However, the sediment thickness where the
embayments intersect the Gulf Coast Geosyncline (30,000 ft.
in the Mississippi Embaymentand40,OOOft. i n the RioGrande
Embayment (Murray, 1961 )) is comparable to reported
aulacogens. Although the evidence does not conclusively
show that the Mississippi and Rio Grande embayments are
aulacogens, the similarity is striking. In attempts to
understand the tectonic origins of the Gulf of Mexico, the
aulacogenic nature of these two troughs must be considered.
