A November 1492 Witnessed Fall: Ensisheim, France
Ensisheim! The King of Meteorites
Born in 1492. Christened in 1727. Baptized in 1881.
T he part icular collect ing genera in which I haunt is t he int ersect ion
bet ween science, cult ure and t he f all of a met eorit e. Using t his
epist emological t riangulat ion, no ot her met eorit e is as import ant as
Ensisheim, t he King of Met eorit es.
Ensisheim.
T he name alone conjures up t he immense dept hs t hat met eorit es hold in our cult ure. For t hose
new t o t he f ield of met eorit ics, t he hamlet of Ensisheim, France is a spirit ual almost myt hical land.
Ensisheim, bot h t he st one and t he t own, are a physical connect ion wit h our past on eart h and our
evolut ion in t he Solar Syst em. For me t here is no great er t reasure wit hin a met eorit e collect ion
t han Ensisheim.
T he st ory as usually t old is t hat short ly bef ore noon on November 7, 1492, a met eorit e f ell in a
f ield just out side t he walled cit y of Ensisheim in Alsace. T he only wit ness was a young boy who
saw t he single st one punch it self a met er deep int o what is now t he rich soil of t he east ern French
count ryside.
When t he cit izens of Ensisheim learned of t he f all, many people want ed t heir own souvenir of t he
event in t he f orm a f ragment chipped f rom t he main mass. As t he crowds descended on t he
helpless st one, t he Chief Magist rat e t ook charge and st opped f urt her dest ruct ion. T he st one was
set at t he door of t he Ensisheim church where it s f ame was soon magnif ied.
On November 26t h, t he “King of t he Romans” King Maximilian arrived in Ensisheim t o consult
privat ely wit h t he st one. Several days lat er, Maximilian declared t he met eorit e t o be a wonder of
God, and t hen chipped of f t wo small pieces of wonder, one f or himself and one f or his f riend
Archduke Sigismund of Aust ria.
King Maximilian gave t he st one back t o t he good cit izens of Ensisheim st at ing t hat it should be
preserved in t he parish church as evidence of God’s miracles. T he st one was suspended f rom t he
church’s choir lof t along wit h an of f icial cit y record describing t he event .
T hen 500 years went by while ot her st uf f happened.
Today, in t he Cit y Hall of Ensisheim, t he 53.831kg main mass is prot ect ed by t he Brot herhood of
Saint -Georges of t he Guardians of t he Met eorit e of Ensisheim.
T he rough edge of my slice, I like t o believe, carries wit h it t he dust of
ages and maybe t he f ingerprint s of King Maximilian or Wolf gang von
Goet he or Ernst Florens Friedrich Chaldni in addit ion t o t hose of my
daught er and son.
So much has happened t o t his met eorit e f or so many years, and
given Ensisheim’s head st art in t he race t hrough t ime is so great , no
ot her t hunderst one can ever cat ch it let alone surpass Ensisheim’s
reign as t he King of Met eorit es.
It is easy t o see t hat t he global circulat ion of Ensisheim will never meet collect ing demands.
However, we must remember t hat t hose who walked bef ore us in t he lat e 1400s, 1500s, 1600s,
1700s, 1800s, and 1900s cared f or t he Ensisheim specimens allowing t heir cont inued collect ion
t ransit ions well int o t he 21st cent ury. But will we do t he same? T he Brot herhood of Saint -Georges
of t he Guardians of t he Met eorit e of Ensisheim can only do so much.
Every cent ury and likely every year, specimens of Ensisheim have grown smaller and smaller,
whet her by int ent , accident , or at t rit ion. Now 518 years int o Ensisheim’s st ay on eart h, we are st ill
f ight ing t he same human avarice t hat disgraced t he init ial Ensisheim mass int o half it s original size.
As an LL6 chondrit e (I choked on t he word ordinary) Ensisheim carries
wit h it cosmic t ales in addit ion t o it s eart hly ones.
For me, not hing says impact and melt as well as a brecciat ed river.
When t he Ensisheim met eorit e was lovingly bat hed in warm soapy wat er in 1881, it was a t urning
point in met eorit e science, met eorit e cult ure, and essent ially was t he symbolic bapt ism of a
met eorit e t o save t he soul of Ensisheim.
Alt hough t he cit y of Ensisheim was deep in debt t hrough polit ical expendit ures including t he
building of a bridge, t he wisdom of t he ages held out and t he main mass of Ensisheim was not
sold of f t o a museum collect ion. Not t hat museums aren’t appropriat e places f or such t hings, it ’s
just t hat once t he pride and ident it y of an ent ire cit y and it s people are ref lect ed t he preservat ion,
at all cost s, of a singular art if act t hat can never have an equal, t he polit icians bickering and
post uring over a budget sheet must look elsewhere t o f ill t heir cof f ers.
For if it were not f or t he great people of Ensisheim, t he King of Met eorit es would, if just lucky,
occupy it s own glass case in a museum somewhere. My guess is t hat if Ensisheim had been sold
int o museum servit ude, it would have been f urt her violat ed int o a display hemisphere devoid of
t he great ness it now possesses sit t ing at op it s t hrone just a st one’s t oss f rom where it landed
over half a millennium ago.
Ironically, it is t o pay homage t o t he Great Ensisheim t hat many cross t he bridge int o t he t own
complet ely unaware t hat t he very over-wat er pat hway t raveled on t heir pilgrimage could have
been t raded f or t he King of Met eorit es.
An odd scar is is visible on t he smallest of t he cut edges. I suspect it
was f rom an unpadded caliper st and where t his slice lived f or some
t ime on display. And when t alking about Ensisheim, “some t ime” could
be cent uries!
T he longest cut edge of t he slice shows more of t he wonderf ul melt
rivers meandering along t his narrow piece of hist ory wit h t he same
dignit y as if it were f lowing across a polished f ace.
Graphic used wit h permission.
At t he spring 1881 meet ing of t he Geological Societ y of t he Upper Rhine, t he st one of Ensisheim
was removed f rom t he Cit y Hall and brought t o an Inn in Gebweiler named T he Golden Angel. T he
main mass was showing more it s neglect t han it s age being “encrust ed wit h a cent uries-old
accumulat ion of dust and dirt .” T he geologist s bat hed t he st one in warm, soapy wat er scrubbing it
clean.
At a Societ y dinner served wit h t he f amous Alsat ian wine known as t he Knight of Alsace, Prof essor
Knop of Karlsruhe cont inued a t radit ion st art ed by Sebast ian Brant by reading a poem about
Ensisheim aloud t o t he group. T he wonderf ul verses present ed below chronicles t he almost 400
year hist ory of t he Ensisheim met eorit e at t hat t ime.
T he Met eorit e of Ensisheim
Fallen on 7 November, 1492
Sonambulent is everlast ing space
T here wanders t imelessly a met eorit e,
Planet -st ruck, in it s dreams
T he numbers of it s brot hers pull it along.
In t he black-ref lect ed light ,
It perceives in ult imat e dist ance
T he wine-cheered f ace of eart h.
It can no longer rest rain it self ,
So long has been t he wait ,
In t he cold of out er space,
Already f rozen int o cryst als,
Now it wishes t o change it s place.
Filled wit h great desire
It scent s, and hesit at es no longer,
T he Knight let of Elass.
T he at t ract ion is t remendous
And it speeds up in it s course;
As soon as it ent ers t he at mosphere
It is slowed wit h a t hunderclap.
Enveloped in heat and shock
In it s headlong f light , it plunged
One met er deep in t he soil.
From Ensisheim t o t he Vosges
T he message spread at once
T hat a st ony guest has arrived
Which had f allen f rom t he sky.
Also Maximilian came,
Accompanied by his advisors
Favorably disposed t oward science
He discussed t he meaning wit h his council.
T hereupon, he cut wit h might y st rokes
Two pieces f rom t he dark st one
And as t rue evidence of a sign f rom heaven
He coolly pocket s t hem.
He spoke: “You shall t ake good care of t he st one,”
To t he burghers of Ensisheim,
“It will bring luck and blessing,
To your communit y.”
In memory of his words
T hey t ook t he promising f ind
And hung it in t he church of t hat place
And t wo hundred and sixt y pounds.
And t here it hung along in piece
Unt il t he priest , overwhelmed wit h f ear,
Saw in it here on t his eart h,
T he devil himself .
T he st one, admired and chipped at ,
Insult ed and jeered at ,
T hat had been diminished t o half it s size,
Was t ransport ed int o t he cit y hall;
Here it lay in an alcove
St ripped of t he church’s blessing,
An angel bound and imprisoned
For almost 400 years.
Unt il now a company of geologist s
From here in t he upper Rhine
Carried it t o Gebwiler
And checked int o t he Golden Angel,
T hey held a lect ure and session
On t he nat ure of t he region,
Wit h research on t he t ime scale,
And on an excursion t hey went .
And when t he ‘Cock’ crowed
About t he coral-met eorit e of Hungary,
Alt hough wit h crying and bickering
T he one f rom Ensisheim was shown,
T hus spake t he st one: If Eozoon
Had not disappeared
T he glorious Cock, who had f ound it ,
Would have recovered it .
T he geologist at once recognized,
Wit h t heir st one-f riendly eye
In him a close relat ive
And t hey mourned his hard f at e.
Wit h wat er, wit h soap and brushes,
T hey scrubbed him t horoughly
And rest ored t o splendor
T he “Prince of t he Sky.”
Now t he st one showed openly it s ident it y,
As a brecciat ed chondrit e;
Pyrrhot it ie grains and nickel-iron
Olivine and chrome-magnet it e
And wit h met allic lust er,
T he st one opened it s eye
And f aced at t he Round Table
T he incomparable Knight let .
T he st one would have loved t o st ay wit h us
But it had t o be guarded very well,
Torn f rom it s lover’s heart s
It was brought back t o it s old imprisonment ;
T here it is st ill await ing salvat ion
For a call f rom Berlin-it would mean,
In view of t he public t reasury,
For bot h a great prof it .
It would be released f rom it s misery,
T he injust ice of hist ory revenged
T he cit izen would be delivered f rom his debt s;
And Maximilian’s prophecy would be right .
And t he lit t le black f ellow
Once banished as a devil
Would be t ransf ormed as a Golden Angel
For t he benef it of Ensisheim.
I’m looking f orward t o t he day when anot her banquet celebrat es t he King of Met eorit es and a
poem is read t o 21st cent ury people. T he poem, f illed wit h words f rom hist ory as well as t hose
f rom our modern world, relives t he elegance of t he past while gracef ully t ransit ioning t o our
int ernet -connect ed responsibilit ies t o Ensisheim.
In t he end, all we can do is say t hank you cit izens of Ensisheim. T hank you f or caring about
generat ions you would never meet . T hank you f or sharing your honest words wit hout f ear a more
scient if ically lit erat e societ y would scorn your belief s. And t hank you f or saving t he King.

I decided t his year t hat I would not work right up t o t he day bef ore we lef t f or vacat ion. So
Sat urday was my last day of work and I got t o do some rest ing up and leisurely packing bef ore we
headed t o t he desert on Wednesday morning. Paul arrived just about exact ly when we had
planned and we st art ed t oward Franconia. We have hunt ed t he sout h side of t he Franconia
st rewnf ield several t imes and never f ound a st one. We have had much bet t er luck on t he Nort h
side of t he st rewnf ield each f inding several. But , as I indicat ed last mont h we were not going on
vacat ion t o really hunt hard. But t o rest and recuperat e f rom work , recline in lounge chairs and
wat ch t he planes f ly over.
Pict ure shot f acing east f rom our camp t oward t he hills of
Palo Verde Mine
Handheld phot o at 18x wit h my Nikon of passenger jet .
We got some gas in Barst ow and had lunch at t he same t ime. T hen it was a rout ine drive across
t he Mohave Desert . We pulled of f t he int erst at e at t he Franconia of f ramp and int ended t o head
over t o t he middle of t he sout h side of t he st rewnf ield where we usually have camped in t he past .
We got a ways down t he dirt road and it was clear t hat t hey had considerable wat er come t hrough
t he washes. T here was f airly deep sand across t he bot t oms of some of t he washes and we
decided t hat it was saf er and smart er t o just go back a lit t le and camp on t he west side of t he
st rewnf ield inst ead. So we headed sout h down t he main dirt road t o a spot where t here was a
large pat ch of desert pavement we could pull of f on and get pret t y f ar f rom t he road. We want ed
t o avoid as much dust as we could since we were really f ocusing on ast ronomy t his t ime out . Dirt
and dust are bad on our equipment . We were able t o get a couple hundred f eet f rom t he road and
t here is so lit t le t raf f ic t hat it was a f ine spot t o camp.
T he weat her t he f irst night was great not a cloud in t he sky. I had my camera adapt er rig I had
worked up all ready t o t ry out . T he Moon was not yet f irst quart er so it was going t o be good f or
phot ograph all t he night s we were t here. Full Moon and near f ull are much less int erest ing t o view
and phot ograph since t he light hit st raight on and lit t le det ail is not iceable. But , I had a great crat er
rich edge t o shoot each night .
T hursday morning it was up early and go hunt ing bef ore it got really hot . We had expect ed t hat
t he t emperat ure would be in t he 80′s as it usually is in mid Oct ober. But it was going t o be 100
degrees and we decided t o hunt just 3-4 hours. We knew our chances f or Franconia met eorit es
was poor wit h all t he work t hat has been done on t he sout h side gridding every area. We were
camping sout h of t he real st rewnf ield so we were really doing new exploring. One piece of desert
t o cold hunt is as good as anot her when it is t he desert pavement t ype det ect ing we were doing.
We f ound our normal select ion of bullet s and wire and bit s of lead and rust ed manmade iron. No
met eorit es were discovered. But , f un was had and we were not in t he of f ice at work.
In t he af t ernoon clouds st art ed t o roll up around us. It is int erest ing how t he clouds f orm t here in
t he Franconia area. We have seen it many t imes. T he clouds will circle t he area hugging t he
mount ains all around and t hen as night comes t hey will move across over Franconia. We got t o do
no ast ronomy on T hursday night . We st ayed inside wat ched a movie and had popcorn. We worked
wit h t he pict ures t aken t he night bef ore. I am using on t he t elescope my older Nikon wit h a f ixed
ext ernal lens. I have an af ocal adapt er t hat I made f or connect ing and keeping t he eyepiece of t he
scope and t he camera lens aligned and cent ered over each ot her. I can st ill use t he t elephot o
range of t he camera t o remove t he darkening t hat shows in t he corners of t he f rame on wide
angle set t ings. Neit her Paul or I have equat orial mount s right now f or our scopes so exposure
t imes have t o be short . And wit h t his af ocal arrangement t he magnif icat ions used are signif icant
and movement of t he image across t he f rame is very not iceable. Fort unat ely, t he Moon shoot s
almost like a daylight object as f ar as apert ure and shut t er set t ing go. T he sharpness is bet t er at
t he f ast shut t er of 1/15t h second but t he sat urat ion and overall color of t he shot is bet t er at 1/8t h.
It is sort of a balancing act . I act ually went ont o aut o and used t he program capacit y of t he
camera t o do most of t he shot s on Friday evening. But , I jump ahead a lit t le.
T his is a 1/8 second exposure using an of f axis mask of 3
inch diamet er wit h no t racking and a very unst able
at mosphere. I st ill like it .
Friday morning, we had breakf ast and sat out side in t he shade and worked hard on doing not hing
t ill mid-morning. We read books. Paul had some comput er programming books and I brought an old
book on st one rings of t he Brit ish Isles. Paul got a lesson on plain and recumbent st one circles and
barrow mounds and he could probably have lived all t he rest of his lif e wit h out learning about
t hem. But , t hey have been a f ascinat ion f or me f or years. We moved our lounge chairs like t he
shadow of a sundial. When t here was nowhere t o be in shade anymore we went inside unt il t here
was shade on t he ot her side of t he mot or home. We had some work t o do and brainst orming t o do
so we t ook care of t hat while t here was no shade. T hen it was more veg t ime t ill evening and we
set up f or sunset shot s again. I set up t he t elescope once more f or more Moon pict ures. We had
caught a f ew pict ures of Jupit er on Wednesday night and looked at all our regular f avorit es. A nice
select ion of galaxies, nebulas, clust ers, and a comet rounded out t he f irst night we were t here.
But , t he big surprise was while we were looking at one sat ellit e go over we saw anot her on a near
“collision” heading and t hat one f lared very bright ly f or a couple seconds. I always f orget t o look up
t he iridium f lare opport unit ies bef ore going t o t he desert . We accident ally got t o see a really nice
one.
Af t er get t ing more Moon pict ures I put t he scope next t o t he mot orhome and we wat ched anot her
movie, wit h plans t o t urn in rat her early so we could get up and hunt met eorit es f or a f ew hours in
t he morning coolness. We decided pret t y early in t he t rip t hat we would drive back t o Bart ow and
st ay at our f avorit e campground. It short ens t he t rip back on Sunday, let s us t ake a shower, get a
hot meal and have wif i t o cat ch up on email and t he met eorit e list . So we were going t o hunt t ill
around 12 noon and t hen go get lunch at t he t ruck st op near Franconia. We drove part way down
t he road t o as near as we could get t o t he west side of t he st rewnf ield and planned t o hike and
hunt int o t he known met eorit e yielding area. We act ually had co-ordinat es f or t he locat ion of John
Wolf e’s f irst f ind so I headed t hat way t o st and on t he very spot . I f igured t here would be a
monument of some kind and t here was. We have GPS t racks f or everywhere we have hunt ed and
a small area of t he west side of t he st rewnf ield was st ill unhunt ed by us so we hunt ed nort h of
John’s f irst f ind and up t oward t he railroad t racks. We looped around and came back t o t he mot or
home. No met eorit es were recovered again, but anot her area is of f our list .
T his is t he lit t le monument of rocks at t he locat ion of John
Wolf e's f irst f ind of a Franconia met eorit e
As I was heading f or t he locat ion of John’s f irst f ine I passed some let t ers made of rocks next t o
t he road. RM, I wonder who made t hem was it one of our met eorit e f riends who has t hose init ials. I
don’t know I will ask him when I see him.
I picked up plent y of nice rocks f or making jewelry. I have over t he years been picking up t he lime
green rock t hat is scat t ered all over t he sout h side. As I was walking back t oward t he mot orhome I
f ound one of t he sources. T here was a vein erupt ing t o t he surf ace of t he green rock surrounded
by a low mound of granit e. I could not help myself and t ook a chunk of t he rock. It should give me a
supply of t he pret t y green st uf f t o last f or a long t ime. Of course I also f ound a lot more 50 caliber
bullet s and ot her st uf f , and one myst ery signal t hat I could not separat e out in t he f ield. I spent
about 10 minut es t rying t o f ind what was making t he det ect or go of f so st rongly. I f igured it was a
piece of lead shot or casing brass. But I could not see it in t he dirt . It was not magnet ic, and having
f ound a lit t le gold in t he past and knowing it is hard t o recognize when covered in dirt I brought t he
whole sample in a baggy back home. I washed it out a f ew minut es ago and t hough I knew
Franconia was not really a gold det ect ing area I had hoped it might be a small nugget . Well it was
a piece of lead just like one would expect . So old t hat it was really incrust ed in whit e lead oxide. It
was not gray anymore at all.
As always we f illed t he week wit h lot s of t hings t o do and also had some great t ime out hunt ing
f or met eorit es. Can hardly wait f or t he next t ime we can get away f or vacat ion. I guess t hat will be
Tucson in February, t hough t hat is a working t rip it is always f un t oo.

Aut umn – t ime f or t he big Munich Show.
Toget her wit h Tucson t he marker, t he indicat or f or t he met eorit ical course of t he f ollowing year.
Warm f all winds best owed days of sun and pushed t he panorama of t he Alps closer t o t he cit y. Full
of expect at ions and pleasant ant icipat ion, having 70 exhibit ors list ed wit h met eorit es in mind, t he
visit or ent ered t he halls. T hough t he longer he walked t hrough t he rows of t ables, t he sharper he
pressed t oget her his pupils f or his hunt ing scheme: dark, brown, black, amorphous, lumpy, not
colorf ul, not shiny – t he more perplexit y crawled up his back. And t he darker t he clouds got over
t he horizon.
Count ryside near Munich, early morning Phot o court esy
Hanno St ruf e
Where are t he met eorit es?!?
Wit h t his out cry as t it le and as a résumé t he Munich report 2010 would be complet ely done.
To give any impressions, we have t o t ake leave f rom comparing wit h t he shows of t he previous
years.
So let ’s st art wit h t he irons.
T he vet eran iron, t he Campo of earlier decades, when “met eorit e” was a synonym f or Gibeon, has
af t er 10 years of prohibit ion f ully disappeared. T he last small box of t he world wit h a f ew rough
specimens was f ound at t he t able of Granddaddy Karl Sprich. Prices quadrupled f rom t he t imes,
Gibeon st ill was f ree.
Sikhot e-Alin is exhaust ed: 4-5 small f lat s wit h small shrapnels, and prices higher t han t hose early
ones, when you st ill could pick out handf uls of bullet s, but t ons, drops, propellers burst ing of f low
lines by t he dozen f rom such boxes. Only t hree somewhat larger pieces on t he whole show.
T he st alls of all our Russian f riends t oget her shrunk t o a combined lengt h of 3 yards. On t heir
t ables, as well as on Bohemian Simek’s, we missed almost all we always were used t o seeing:
Brahins, Chingas, Seymchans.
Hanno St ruf e and Dima Sadilenko (Comet shop) Phot o
court esy Hanno St ruf e
Table of Viacheslav Kalachev Phot o court esy Hanno
St ruf e
Gebel Kamil – af t er t he f urious impact in Ensisheim, it seems f ully volat ilized again. Only a f ew
specimens here and t here and a modest box under t he t able. As small comf ort f or t he
disappoint ed collect or, at least a f ew small et ched slices at a very af f ordable 2-3$/g were
available. Morasko? Nil ret urn.
T he only const ant – like on every show – was of course ever-smiling Hans Campo Koser wit h his
hundredweight s of Campo del Cielos in all sizes and shapes. While t he visit or lost his smile, when
he remembered t hat t wo, t hree years ago, st ill ot her prices were not ed on t he price t ags.
Diet er Heinlein, Hans Koser, Hanno St ruf e and Mike Farmer
Phot o court esy Hanno St ruf e
T he silicat ed NWA-iron wasn’t available anymore in ent ire pieces.
Badly missed were all our Aust ralian f riends.
T he bright spot , t he Davidssons wit h a set of exquisit e Henburys wit h perf ect pat ina and excellent
shapes, some even resembling Sikhot e-Alins. One has t o go f ar back in t ime, t o remember t o have
seen, such an assemblage of such museum-qualit y Henbury.
T he Davidssons had a lot of f irst class Henbury irons f or
sale Phot o court esy Hanno St ruf e
Iron of t he season was, like last year t oo: Muonionalust a.

t o doubt in t heir belief t hat such names would be available only in molecular sized microspecks.

Posit ively t o remark, was t his years enlarged availabilit y of Impact it es and t ekt it es. Finally again
black indochinit es of all sizes and shapes were basket -wise of f ered (<30$/kg). And also t he choice
of moldavit es was bet t er t han ever. Here t o ment ion expert T homas Dehner, who also just has
edit ed a new book about moldavit es. Good larger quant it ies, just like last year, of Libyan desert

No good show wit hout out a novelt y.
So as poor as Munich was, at least vet eran dealer Uwe Eger rescued t he event in t his respect t his
year. He displayed ext remely t hin slices of a new pallasit e f rom Indonesia. Wit h st rangely small

T he charact er of Munich 2010 wasn’t only t he lack of met eorit es, but also t he absence of many

I don’t t hink CK met eorit es are much t o look at except t hose rare slices wit h huge, gnarly CAI. You
pret t y much get dark chondrules in dark mat rix. I have one f airly dense slice t hat someone
polished which made f eat ures essent ially disappear. T hankf ully t hat wasn’t done t o t his slice.
Since t his is a CK4 chondrules are easy t o see scat t ed in t he mat rix. T his view is an
inch wide. NWA 4657.
We see a lot more in t hin sect ion under a ‘scope. T his is an odd shot I made wit h
ref lect ed light plus some light coming t hrough t he sect ion f rom below. It shows quit e a
mix of t ext ures and mat erials in a port ion of a large chondrule. T his pict ure and t he
next show layering f rom mult iple accret ion and heat ing event s.
Large grains are in t he int erior of t he chondrule, around t hem (below) is a rim f ormed
f rom melt . It is peppered wit h opaque blebs. Furt her out (yet lower) are a couple layers
of f ine mineral grains t hen a jacket of dust .
Evidence of t urbulent t imes - f ragment s of broken chondrules.
In t his port rait t he BO chondrule at t he right is missing it s lower right side. T he curved
f ragment in t he pict ure above is a perf ect mat ch in size, shape and even orient at ion.
But it ’s hard t o believe t hey are mat es t hat got separat ed, st ayed close during f inal
parent body assembly and were sect ioned perf ect ly in t his slice. It is even harder t o
believe t hat t hey are not relat ed.
T his is t he object in t he lef t of t he port rait above, a granular olivine chondrule. It
cont ains blebs of opaque mat erial and has a rim of coarse grains.
T his large dif f use f eat ure cont ains a couple round dark areas surrounded by bright
grains.
It would be int erest ing t o know what mechanisms were at work here.
T he bars in t his chondrule are t he same color as t he rim where t hey join it . T hat is,
t hose bars and t hat port ion of t he rim are in opt ical cont inuit y, t he cryst al st ruct ures
are aligned. For example t he bars t hat reach t he rim f rom t he noon posit ion t o one
o’clock are light orange and so is t he rim. To t he right , t he bars t hat t ouch t he rim at
t wo o’clock are green as is t he rim. T his cont inuit y is common. T he f un t hing here is
t hat t his cryst alline orient at ion ext ends beyond t he igneous rim. We see t hat t he
mineral grains t hat were f orming f rom t he surrounding dust or mat rix grew,
“recryst allized”, wit h t heir cryst al mat rix in t he same orient at ion as t he nearby rim and
t he bars on t he ot her side. T his is seen best when t he polarizing f ilt ers are rot at ed
and, f or example, t he green bars, green rim and green speckles beyond go in and out
of opt ical ext inct ion t oget her.
Speaking of rot at ing f ilt ers, t his animat ed GIF st eps t hrough f our pict ures t o emphasis
t he dif f erent cryst al domains in t his sharp chondrule t hrough ninet y degrees of
rot at ion. T he horizont al slide remained st at ionary and a horizont al polarizing f ilt er
above it and a horizont al polarizing f ilt er below it were moved in unison. T he f ilt ers
began and remained wit h t heir direct ion of polarizat ion in a crossed orient at ion t o
each ot her. Consider t he bright , complet ely illuminat ed shot as zero degrees. T he next
pict ure was t aken wit h t he f ilt ers rot at ed (about a vert ical axis) approximat ely 23
degrees. T he next pict ure is af t er anot her 23 degrees. And t he f ourt h af t er a t ot al of
about 68 degrees. At 90 degrees t he view is t he same as t he f irst pict ure, which is

T his art icle is direct ed at t he silent newbie or bef uddle beginner who is sort ing t hrough t he
conf using groups of met eorit e t ypes and t rying t o f ind t heir way around t he world of space rocks.
Many new collect ors of t en want one of each t ype of met eorit e. Many vet eran collect ors abandon
t his pursuit because t he t ask is quit e daunt ing. So when you hear t alk about “t ype collect ing”, or
building a “t ype collect ion”, what exact ly does t hat mean?
I hope t he f ollowing brief art icle will answer t hose quest ions, or at least point t he reader in t he right
general direct ion. Not e, I gleaned much of t his t ype inf ormat ion f rom David Weir’s aut horit at ive
websit e “Met eorit e St udies” and f rom t he Met eorit ical Bullet in. I do not claim t hat t his list is 100%
complet e or wit hout error, so if t he reader spot s an error or omission, please reply and correct it .
I st art ed out collect ing met eorit es wit h a small sample of NWA 4293 – an ordinary high iron
chondrit e of t he H6 t ype. It was about t he size of a dog-f ood kibble and it looked like one. But I
was inst ant ly hooked, and I want ed t o have one each of t he dif f erent t ypes of met eorit e. T his is
known as “t ype collect ing” or building a “t ype collect ion”.
T he danger of t ype collect ing (besides t he damage t o one’s checking account ) is t hat t he various
pet rologic t ypes are subdivided int o various grades according t o met amorphism.
For example, t ake t he H chondrit e group t hat my NWA 4293 sample belonged t o.
T here are H3 chondrit es, H4 chondrit es, H5 chondrit es, and H6 chondrit es. Did I really need one
each of t hese subt ypes? Well, it depends on how deep a collect or want s t o go int o t he rabbit hole.
T here are dist inct dif f erences bet ween t he various H t ypes.
T he number at t ached t o each is more t han just a simple weat hering grade or shock grade. It
represent s a progession in t he H-chondrit e f amily f rom least alt ered t o most alt ered. H3
chondrit es are loaded wit h chondrules, H4 have some chondrules, H5 has f ew chondrules, and H6
has virt ually no visible chondrules. A new grade of H7 has been added as well. So, a collect or could
simply have a single Hx chondrit e and say t hat t he H-chondrit es are represent ed. Or, t he collect or
could have one each of t he dif f erent subt ypes f rom 3 t o 7.
Anot her peril is t he changing of nomenclat ure. For example, t he K-subgroup of carbonaceous
chondrit es was only recognized and designat ed in 1990. Up unt il t hen, Karoonda was considered a
CV4 met eorit e of t he Vigarano f amily. Now Karoonda is recognized as dist inct ly dif f erent t ype of
carbonaceous chondrit e, so it was made int o it ’s own group. Now we have CK4, CK5, and CK6
met eorit es – all represent a progression in met amorphism and have visible (and chemical)
dif f erences f rom ot her grades. T here are st andout members of each subgroup, so where does
one draw t he line?
Should t he collect or acquire a sample of Karoonda and be done wit h it ? Or should one go out and
t rack down CK4, CK5 and CK6 met eorit es? Again, it depends on how ext ensive and exhaust ive a
collect or want s t o be wit h t heir t ype collect ion. Budget will also play a role as well, because an
exhaust ive t ype collect ion is a daunt ing project .
Last ly, one must consider t he ungrouped met eorit es. T hese are oddball met eorit es t hat do not
neat ly f it int o t he pre-exist ing met eorit e t ypes. T here are ungrouped chondrit es, ungrouped
achondrit es, and ungrouped irons. No t ype collect ion can overlook t hese met eorit es because
some of t hem are t ypes unt o t hemselves wit h unique qualit ies.
For t hose who want t o build a def init ive and complet e t ype collect ion, here is a list of every known
t ype and subt ype of met eorit e. T his list was culled f rom ot her sources, including David Weir’s
