Meteorite-Times Magazine Witnessed Fall: Alfianello, Italy by Martin Horejsi Like Sign Up to see what your friends like. An February 1883 Witnessed Fall: Alfianello, Italy A Beauty Forged by Air. A Form Destroyed by Rage. A Treasure Lost through Excess. My specimen of Alf ianello reminds me of a polished rock bookend sold by t he pair in small t own gif t shops. It s weight in can be measured in pounds, and it s dimensions in inches- including it s t hickness. Of course met ric unit s are t he indust ry st andard, but US measurement can be so much f un since t heir crude precision is smug wit h irresponsible surplus. Making it s debut at t he Accret ion Desk is an f aux ant ique scale cube creat ed by Tom Phillips. Tom calls t hese cubes “Mart in Cubes” af t er me because he t hought I would like t hem given my int erest - make t hat obsession- wit h hist oric wit nessed f alls. Tom was right , and he can be cont act ed at : st [email protected] . It was an int erest ing morning when I got a slab of It alian hist ory f rom Bob Haag. T he day bef ore, while at t he 2005 Tucson Show, my collect ion t urned a corner in st at us when Bob passed a whole handf ul of t orches on t o me…f or a price of course. Bob and I were going t o complet e t he deal t he f ollowing day, so when I showed up t he next morning, I quizzed Bob about t he Alf ianello sit t ing in his display case bef ore complet ing our deal. He named a price, and in an rarely used but highly pract iced reply, I agreed t o t he sale wit hout really t hinking about it . In f act I didn’t need t o t hink much at all because deep down in my subconscious, t he mere act of asking was already it s own answer. Fusion crust engulf s one edge of my slice like black on a charred log. or Sensuous undulat ions of f rozen liquid rock embrace t he regmaglypt s like black silk sheet s clinging t o sweat y lovers. In real est at e, one can use market values of similar propert ies f or comparison. But in t his case, t here was not hing like it available in t he world (t o my knowledge anyway) and t here hadn’t been in a long t ime (as f ar as I knew). Was it old? Yes, well over a cent ury. Did it have crust ? Yup. Plent y. A rich collect ion hist ory? Richer t han a $10 chocolat e t ruf f le. What about T KW? Well, t he aimless blade of science-t o quot e Neil Young- would say t here are 228kgs t hat f ell f rom t he sky. But a recent global collect ion invent ory of Alf ianello could account f or less t han a quart er of t hat amount . So wit h ~50kgs account ed f or, t hat means t hat my piece of Alf ianello represent s at least 2% of t he t ot al known mat erial. And given t he number of smaller pieces in collect ions, it also places my piece in t he upper echelons of size. Rare class? Good t hing I don’t worry about such t rivial det ails as classif icat ion. And so what if Alf ianello is t he most common met eorit e class in t he solar syst em. All kidding aside, alt hough Alf ianello is an L6 chondrit e it does have some large chondrules including one very nice megachondrule. T here is also enough shiny met al f lake t o keep a whole school of bass busy all day. T his East er Egg of a megachondrule overpowers every ot her int ernal f eat ure on t his slice. I f igure t hat any t ime one can use a scale cube t o show t he size of a chondrule, it ’s a good t hing! But I digress. Alt hough adding t he purchase of Alf ianello t o my pile of amazing met eorit es raised t he t ot al I spent wit h Bob t hat weekend by half again as much, I knew t hat t here was no way such an opport unit y would ever come my way again, or at least again bef ore my wallet had a chance t o recover. A rich collect ion hist ory? What could be bet t er t han t his? Oh, ok. I can imagine bet t er t oo, but you’ve got t o admit t hat provenance f rom t he f amous Humboldt Universit y Museum in Berlin f ollowed by t he Robert A. Haag collect ion is hard t o beat t hese days. On May 26, 1883, t he Stevens Point Journal newspaper in St evens Point , Wisconsin ran a st ory about t he Alf ianello f all. A f ew not able point s in t he playf ul slice of newsprint hist ory include t hat t he met eorit e was hot , st unk, and most of all, shaped like a t runcat ed cone. A t runcat ed cone? A quick google search f or “t runcat ed cone” yields a f irst hit f or wikipedia’s ent ry f or f rustum t hat cont ains t he f ollowing line: “In the aerospace industry, f rustum is the common term f or the f airing between two stages of a multistage rocket (such as the Saturn V), which is shaped like a truncated cone.” Cool! Here’s t he t ext f rom t he art icle: An Aerolite T he Rome correspondent of t he St . James Gazet t e says t hat on t he 16t h of February some peasant s working in a f ield near Brescia were st art led by hearing a loud report like t hunder. Looking up t hey saw t he clouds t orn open, and a large body f ollowed by a t rain of bluish smoke hurt ling t hrough t he air over t heir heads wit h t he noise of an express t rain. T he aerolit e buried it self in an adjoining f ield, t he f all causing a shock like t hat of eart hquake. It was f elt t en kilomet ers away, while t he report was heard at Verona and Piacenze, many miles dist ant . When t hey had recovered f rom t heir f right t he peasant s hurried t o t he spot , and f ound a clean hole about t hree f eet deep running in an oblique direct ion f rom nort hnort heast ; and on digging down t hey came t o a solid block, in t he f orm of a t runcat ed cone, weighing f rom f our t o f ive hundred pounds. T he surf ace, which was st ill hot , and emit t ed a sulf urous smell, was covered wit h a greenish black crust , f ull of small holes, such as would be made by f inger-t ips in a sof t past e, which may have given rise t o t he report t hat one of t he f ragment s bore t he impress of a hand. T he propriet or of t he clover-f ield in which t he aerolit e f ell f lew int o a rage at his crops being t rampled down by people coming t o see it , and broke it up, when it was carried away piece meal. So he gained not hing but damage t o his f ields, while t hose who picked up t he pieces f ound a ready sale f or t hem, one man get t ing as much a seven t housand f ranks f or a lump t hat weighed t went y-f ive pounds. On a subsequent search by Prof essor Bombicci, of Bologna, several pieces of scorize, apparent ly det ached f rom t he aerolit e in it s f light , were f ound in t he neighborhood.” As you can read, t he beaut if ully orient ed 228kg individual of Alf ianello was broken t o pieces t hrough t he rage of t he caret aker. But had t he f armer played a dif f erent card, he might have had t he st ory of one of t he world’s most f amous orient ed st one met eorit e f alls in hist ory f orever linked t o his f amily name in t he hist ory books. Sadly, even when st ones f all f rom t he sky t oday, t hey of t en suf f er t he same f at e of shallow minds who misdirect t heir f rust rat ions, or expect int ernally buried t reasure. On anot her not e, it seems t hat “Prof essor Bombicci of Bologna” was a busy man. Here are t wo links f or his legacy. T he f irst is f or t he L. Bombicci Mineralogy Museum, and t he second is f or a specimen collect ion card f rom t he Luigi Bombicci Mineralogical Museum at t he Universit y of Bologna f ounded 1860. Even t he so-called ordinary L6 is f illed wit h jewels f rom our ancient solar syst em. Under a microscope or magnif ying glass, t his slice of cosmic propert y provides acres and hours of enjoyment as you discover t he shapes, colors and f eat ures jam-packed int o a seemingly monot one st ruct ure. You can mouse-over t he images bot h above and below t o compare real color t o invert ed color. By doing so, dif f erent f eat ures- and f eat ures wit hin f eat ures- in t he Alf ianello mat rix jump out . Anot her more t echnical art icle was published in t he Proceedings of t he Royal Societ y of London, Vol. 35 (1883), pp. 258-260. Here is an excerpt f rom t hat art icle addressing t he circumst ances of t he f all and recovery of Alf ianello. Examination of the Meteorite which f ell on the 16th February 1883, at Alf ianello, in the District of Verolannova, in the Province of Brescia, Italy. By WALT ER FLIGHT, D.Sc., F.G.S. Communicat ed by Prof essor G. G. St okes, Sec. RS. Received May 17, 1883. I gat her f rom a short preliminary not ice, which has been sent by M. Denza t o Prof essor Daubree, and has been published in a recent number of t he ” Compt es Rendus,” a f ew part iculars respect ing t he f all of t his st one, and it s general appearance. T he f all t ook place, wit h a loud det onat ion, at 2.55 P.M. on t he day above ment ioned; it was heard in t he neighboring provinces of Cremona, Verona, Mant ua, Piacenza, and Parma. In Alf ianello it is described as épouvant able (a French adject ive meaning appalling or dreadf ul). It descended f rom N.N.E. t o S.S.W., at a dist ance of about 150 met res f rom a peasant , who f ell f aint ing t o t he ground; t elegraphic wires were set in mot ion, and t he windows were shaken. It st ruck t he ground about 300 met res sout h-west of Alf ianello, in a f ield on an est at e called Frosera, penet rat ing t he soil, in t he same direct ion as it passed t hrough t he air, f rom east t o west , t o a dept h of about 1 met re, t he pat h t hrough t he soil being about 1.50 met re. When t aken out of t he ground it was st ill a lit t le warm. It f ell complet e, but was at once broken t o pieces by t he f armer of t he est at e. T he st one is oval in f orm, and somewhat f lat t ened in t he cent re, t he lower part being larger and convex, like a ket t le, t he upper part being t runcat ed. T he surf ace is covered wit h t he usual black crust , and st rewn wit h lit t le cavit ies, now met wit h as individuals, now in groups, and in t he eye of some people bearing a resemblance t o t he impression of a hand or t he f oot of a she-goat . T he st one weighs about 200 kilos. In st ruct ure t his met eorit e belongs t o t he group Sporadosideres oligosideres, and resembles Anmalit e, being almost ident ical wit h t he met eorit e of New Concord, Ohio. Except f or t he megachondrule, t his region of Alf ianello mat rix could be considered a random snapshot generalizable t o all Alf ianello mat erial. T he more t ime you spend looking, t he more you will see. But don’t f orget t hat t he pict ure above represent s only about f ive cent imet ers across. While t he arrival of Alf ianello was a major impact f or t he year 1883, it was not t he great est . T hat honor goes t o t he f amous erupt ion of Krakat oa volcano in August . T here are many report s t hat up t o a year af t er t he erupt ion human skelet ons f loat ed across t he Indian Ocean on raf t s of volcanic pumice only t o wash up on t he east coast of Af rica. Just imagine how t hat would be explained! It would make t he f all of a large hot st inky rock f rom space seem odd, but not t erribly unusual.

Anot her Tucson Gem and Mineral Show is in t he hist ory book. What an excit ing t rip it was f or Paul and I. We t ook an ext ra day t his year and it made a big dif f erence in t he way t he week went . It was a lit t le more relaxed and we had a chance t o f ind a f ew more great it ems t hat we might ot herwise have missed. We got int o t own about 1 pm on Wednesday and headed st raight away t o f ind met eorit es at a secret locat ion of f t he beat en pat h t hat we hit each year.. We f ound t he met eorit es and some great Moldavit e t oo. In less t han one hour, t wo of t he it ems on our “really want list ” were checked of f . We st opped brief ly at t he f ormer Inn Suit es and saw some people. T hen it was of f t o t he hot el t o check in and get some lunch. T he night was likely t o run lat e wit h t he screening of Met eorit e Men t op of t he list of places t o be. So having had our hot el room given away once many years ago we t ry t o check in bef ore night t ime act ivit ies. Back on t he road about mid af t ernoon we were back looking at met eorit es around t own. I had a short list of it ems I was personally looking f or. Of course t here are always many ot her met eorit es t o see t hat I f ind int erest ing. Almahat a Sit t a t he met eorit e f all t hat had been t racked f rom space t o t he ground a f ew mont hs ago was one I really want ed t o check out . Anne Black had delight f ul pieces in her room of t his unique met eorit e. Not only is it t he only met eorit e t hat was a t racked ast eroid bef ore breaking up in our at mosphere and spreading it self across t he ground. But it t urned out t o be an unusual t ype. Polymict Ureilit es are about as rare as ones t racked bef ore f alling. Anne Black and Geof f Not kin have shared a room at t he show f or t he last f ew years and while t here one of our early visit s Geof f generously present ed Paul and I wit h Aerolit e Met eorit e ball caps. T his will be a t reasured mement o which I will also wear wit h pride. T here was a t remendous variet y and beaut if ul present at ion of met eorit es in t heir room. It is just a great place t o hang around. For very soon any one you are looking t o f ind will appear. I t hink by t he end of t he week I had only f ailed t o see one or t wo people on my “people list ”. I had been looking f or Nerf t one of only f our met eorit es f rom Lat via f or a f ew years. I knew t hat Morit z had some last year t hat I had missed And t here it was in Mike Farmer’s roomt his year. So af t er get t ing it I am just one met eorit e away f rom complet ing Lat via. We had some f un get t ing a 1 kilo of small Gaos f rom Mike. Not hing beat s sit t ing on a comf ort able couch and picking t hrough bags of met eorit es. It is not as much f un now t o go home and have t o clean t hem up a lit t le. Af t er 50 years t hey are showing a rust y color on t he surf ace. But , it most ly disappears wit h some t oot h brushing. I have had a “probably never get ” list wit h a f ew met eorit es on it . Chassigny was t op of t hat list . But ,. I f ound some t his year and it is now part of my collect ion. Who would have guessed. To be honest t hough; t he f ragment is cert ainly t he smallest in my collect ion as well. I have several individuals and slices of Allende. When I saw t he one I got t his year in Erich Haiderer’s room it was love at f irst sight . I t hink it is maybe t he most CAI rich slice per square inch I have ever seen. We were showing what we had bought t o Paul’s brot her Tony and he said one of t he Calcium Aluminum Inclusions looked like a ghost . I t hink he is right . Allende slice overf lowing wit h dif f erent kinds of CAIs T he Ghost CAI I had a good year wit h f inding orient ed irons. I have slowed down buying t hem. I just get a couple each year. I f ound t wo very nice Sikhot e Alins and t wo great Taza individuals. One of t he SAs Paul named t he Rat Poop met eorit e and t hat name will st ick I t hink A remarkable Sikhot e Alin which will always have a st range name Two orient ed Taza specimens T he t wo Taza met eorit es I got f rom Bruno and Carine. While t here t hey let me t ake a couple pict ures of some ot her special it ems t hey had. T he Fukang f ull slice was spect acular. T he crat er in t he Sikhot e Alin is quit e remarkable as well. Full slice of t he Fukang pallasit e A large crat er in a Sikhot e Alin individual T he f irst morning is always when we st op by Blaine Reed’s room and we did not deviat e f rom t radit ion t his year. I f ound a couple pieces t here, but t he f un is always get t ing t o t alk t o him and hear his opinions on t he met eorit e world. One of t he ot her rooms at his hot el had some st ones last year and I got a couple. T his year we swung by t here t o see if he had any met eorit es again. Well he did. He had t he same t hree st ones I had lef t behind last year. Two t hat were very quest ionable as being real and one t hat I had not got t en in ‘09. So you know t he next part . I got it t his year. Now he just has t he t wo int erest ing maybe or maybe not st ones. I guess I can look at t hem again next year. T he business had bought a big bat ch of st uf f and we needed t o send it home. A st op by a shipping boot h got t hat big load of iron and st one of f our minds. We don’t like t o leave anyt hing in t he rent al car so it get s t ough t o carry everyt hing wit h us. Wednesday night was t he screening of anot her episode of t he Met eorit e Men Science Channel series. It was great t o gat her t oget her as a large group of met eorit e ent husiast s and wat ch it t oget her. T he commercial breaks were cert ainly more f un t hen at home wit h Geof f and St eve ent ert aining us during t hose t imes of advert isement s. Having arrived just t hat af t ernoon it was also t he f irst occasion t o see many of our f riends. What a wonderf ul evening of f un. In f act every evening of t he t rip t his year had some event f or us t o at t end. T hursday was t he IMCA dinner. T he Met eorit e Exchange had never at t ended bef ore. We had gone out f or dinner as a small group of f riend in years past . I t hink we will enjoy many more IMCA dinners in t he f ut ure. It was also a nice opport unit y t o make new f riends and reconnect wit h f riends we had not seen in a while. On Friday night t he Birt hday Bash f or Geof f and St eve brought around anot her chance t o have Pizza. T he f ire dancers were a hit I t hink. T his year’s Harvey Awards were given out t o a very deserving group of recipient s. And Geof f f avored t he crowd wit h some songs af t er t he regular program ended. A spect acular evening as always. Sat urday night is Michael Blood’s Met eorit e Auct ion. Unf ort unat ely I can not comment on it . For t he f irst t ime ever I missed it . I underst and f rom t he t hings I have read t hat it f inished up early and went of f well. We had an absent ee bid in and won t he it em. So Paul and I were happy t o hear t hat . We spent a very wonderf ul evening out t o dinner wit h t wo members of Paul’s f amily who had driven over f rom Phoenix. Sorry t o say t his Michael, but I don’t t hink eit her of us missed going t o t he auct ion. We were having so much f un, laughing, t ell and hearing st ories t hat it was act ually 45 minut es af t er t he Out back closed bef ore we not iced we were t he only people t here (and t hat t hey were cleaning up). We had lef t a nice t ip, but it was really nice of t hem t o not t hrow us out . Sunday morning t here was really only t ime t o make a f ast pass t hrough t he Inn Suit es t o say some goodbyes and set t le up some bills. I needed t o pay Anne Black f or several pieces. T hen it was of f t o t he Airport by way of a gas st at ion. $5 a gallon if we don’t f ill t he t ank. I act ually got t urned around and messed up a couple t imes driving t his t rip. Maybe once a year is not enough t ime t o spend in Tucson. Especially wit h so many f riend living t here now. We f ound what we had want ed t o get f or t he business, we saw almost everyone we hoped t o see. We met many new people we had only known f rom emailing. I f ound some nice pieces f or my collect ion. As Tucson Gem and Mineral Shows go t his may have been t he best so f ar.

This Month’s Meteorite Market Trends by Michael Blood Please Share and Enjoy: Meteorite-Times Magazine The Arizona Meteorite Exhibition (2010) by Robert Verish Like Sign Up to see what your friends like. T he f irst-ever LPL event was well-attended. Hopef ully there will be more Exhibitions in the f uture. In my opinion t he f irst -ever Arizona Met eorit e Exhibit ion was a huge success. It was host ed by, and was t he “kick-of f ” event celebrat ing t he 50t h anniversary of t he Lunar and Planet ary Laborat ory (LPL) locat ed on t he Universit y of Arizona campus in Tucson. It brought t oget her Arizona met eorit e f inders, classif iers, researchers, and collect ions. T he event f eat ured exhibit s of Arizona met eorit es and met eorit e collect ions, as well as, inf ormat ive displays, lect ures, and post ers. T he event was held in t he At rium of t he Kuiper Space Sciences Building. Dolores Hill should be congrat ulat ed f or a large part of t he success of t his event . She and her colleagues conduct ed a monument al ef f ort t o cont act f inders and classif iers and collect ors of Arizona met eorit es, and t hen t o arrange t o have t hese people and t heir met eorit es brought t o t his event in order t o mingle wit h t he LPL researchers and t o meet t he general public. Just t he making of labels and t he set t ing up of t he display cases and post ers was a laborious t ask t hat wasn’t f inally complet ed unt il just minut es bef ore t he doors opened at 6PM (January 30t h). Post card f rom Exhibit ion is now a “collect ible” Alt hough t his Exhibit ion was widely publicized bef ore t he event (evidenced by how well-at t ended it was), I f ound t here was only sparse report ing on t he Int ernet af t er t he Exhibit ion. It may be a result of t he Tucson Show f ollowing immediat ely on t he heels of t he Exhibit ion. But t he f ew people t hat did report on t he Exhibit ion did such a f ine job of giving a genuine port rayal of t he event , t hat I am going t o depart f rom my usual art icle layout and, inst ead, will have my “Ref erences:” sect ion immediat ely precede my image gallery. I know t hat , speaking f or myself , t here was a very short period of t ransit ion-t ime f rom t he Exhibit ion t o t he Tucson Show. So short , in f act , t hat I wasn’t able t o pick-up f rom Dolores Hill t he met eorit es t hat I had loaned f or t he Exhibit ion display unt il af t er t he Tucson Show! By t he way, t he met eorit es f rom my collect ion t hat I loaned f or display were: Bluebird Franconia – t he f irst one, f rom which t he t ype specimen was classif ied. Gold Basin (L6) – a.k.a.,”Hualapai Wash 010″ Red Dry Lake 002 t hrough 009 Sacrament o Wash 002 – f rom t he classif ied st one (f rom which t he t ype specimen was obrt ained). Warm Springs Wilderness – an endcut f rom t he classif ied st one (f rom which t he t ype specimen was obrt ained). Willcox Playa 002 Willcox Playa 004 Willcox Playa 005 Willcox Playa 006 Willcox Playa 007 Due t o t ime const raint s and t he size of some of t he specimens, not all of my met eorit es got t o be displayed. T he f ollowing images are of t hose specimens t hat didn’t get t o be displayed: Bluebird (L6): “Hualapai Wash 010″: Willcox Playa 004 (L6 S4 W2): Willcox Playa 005 (H5): Willcox Playa 006 (H6): Willcox Playa 007 (L6 S2 W1): Will there be other Ariz ona Meteorite Exhibitions in the Future? I can only hope so. But , I asked Dolores Hill t his same quest ion, and she point ed out t hat t his was all part of a 50t h anniversary celebrat ion f or t he LPL and she sincerely hopes t hat it won’t be anot her 50 years bef ore t he next Exhibit ion, but she hopes t hat whoever runs t he next event t hat t hey have a less arduous job get t ing it organized. Possibly using anot her venue, t here could be a f ut ure Exhibit ion sooner. Maybe hold it at ASU? But given t he rat e of increase in t he number of AZ met eorit e f inds being made, we may need t o hold t he next Exhibit ion at t he Convent ion Cent er! Even if it has t o be held elsewhere, I do hope t hat t here will be more Arizona Met eorit e Exhibit ions in t he near f ut ure.

Chuck, T hank you f or slicing up a f ew of my NWA 869s f or me. Per our deal I’m sending half t he slices back t o you. You say you’re going t o give t hem away t o kids but you ought t o keep t hat one wit h t he armored chondrules t o show around. I put it in a membrane box t o keep it separat e. Armored chondrules aren’t rare but t hey st ill seem special. Maybe it ’s t he name. Armored. Sounds subst ant ial. T hat shiny ring we see around sliced chondrules is a sect ion t hrough a met al-sulf ide shell t hat more or less coat s t he chondrule. One explanat ion f or how t hese came int o being is t hat during chondrule f ormat ion met al-sulf ide droplet s, what ever t heir origin, separat ed f rom t he silicat e melt and gat hered on t he surf ace of solidif ying chondrules – dubbed “expelled” coat ings. Anot her suggest ion is t hat MS vaporized during chondrule melt ing and t hen deposit ed on chondrule surf aces during cooling – “recondensed” coat ings. [Summarized by Vogel et al. (2004) in MAPS.] Anot her scenario invokes impact mobilizat ion of MS, f ragment at ion of t he parent body and subsequent reaccret ion – an impact and reaccumulat ion process. [Kojima et al.

T his f eat ure is devot ed each mont h t o one of t he personalit ies wit hin t he met eorit e communit y. T his mont h we are delight ed t o share an int erview we had wit h Tracy Lat imer. Myself and my husband wit h a f ew of our t oys in t he back yard. Met eorit e-Times (MT ) What or who got you int erest ed in met eorit es and how old were you when you got your f irst met eorit e? Tracy Lat imer (T L) I st art ed collect ing about a decade ago. I was looking f or unique Christ mas gif t s online, and having been recent ly int roduced t o ebay, on a whim t yped in ‘met eorit es’. I was ast onished t o f ind t hat t hey were available f or t he public t o buy. I bought all my f riends t iny met eorit e samples f or Christ mas t hat year, and spawned my own int erest at t he same t ime. (MT ) What was your f irst met eorit e? (T L) I bought a bunch at approximat ely t he same t ime; t he one I remember f rom t hat f irst bat ch is a skelet al Imilac, wit h all t he olivine weat hered away. (MT ) Do you st ill have it ? (T L) Yes. (MT ) Do you have special areas of int erest t hat you f ocus on in regards t o met eorit es (t hin sect ions, phot ography, chemist ry, age dat ing.. et c)? (T L) Ideally I’d like pieces f rom every unique f all or f ind, but t hat just isn’t in t he budget . I have a f ew gaps, but I’ve been working on get t ing a represent at ive piece f rom every pet rologic grade and t ype. Recent ly I’ve been concent rat ing on lower pet rologic t ypes, t he L3s and LL3s; I f ind t hem aest het ically pleasing. I also f ind it hard t o t urn down nice pallasit es, which are as beaut if ul as st ained glass windows; I wish I had more unique specimens. (MT ) Does your Family share in your int erest in met eorit es? (T L) T he overall react ion seems t o be “Well, isn’t t hat f ascinat ing,” and I t ry not t o bore t hem t oo much wit h met eorit e t rivia! My parent s recall t aking me t o Met eor Crat er as a young child, and t hey say t hat at age 5 I knew exact ly what caused t he crat er. My husband support s my ent husiasm, alt hough he is long-suf f ering. (MT ) Do you have any special approaches t o collect ing? (Type collect ion, only st ones, only irons, only by aest het ics, et c. or any and all t hat you like.) (T L) Most of my met eorit es are micro specimens, as my display area is small; I have only a couple dozen pieces t hat are t oo large t o f it in a 1×1 gem jar. Ot her t han t hat , anyt hing is f air game, alt hough I’m t rying f or at least one of each specimen t ype. A very dat ed pict ure of some of my collect ion; it has since more t han doubled in size. (MT ) Do you mind saying how many locat ions your collect ion represent s? (T L) I am lucky enough t o have specimens f rom all 7 cont inent s, and more t han 300 unique f alls or f inds. (MT ) Is your collect ion displayed or kept in a dry box or bot h? (T L) Most of my met eorit es are displayed in shadowboxes, and a couple of convert ed t ypeset t ing drawers, in individual gem boxes. (MT ) In what ways do you use your comput er f or met eorit es? (T L) If it weren’t f or my comput er, I doubt I would have ever got t en st art ed collect ing! My comput er let s me look at collect ions f rom around t he world, f ind out what is new in t he world of met eorit es, and converse wit h f ellow collect ors, dealers and scient ist s. I also use a spreadsheet t o keep t rack of my collect ion, and make labels f or my display. (MT ) Do you ever hunt f or met eorit es? (T L) I’d love t o part icipat e in a hunt somet ime, but I’d have t o go some dist ance t o search a st rewnf ield. T he rocks in Hawaii closely resemble met eorit es, so visual inspect ion is not t oo usef ul; t he iron cont ent is even high enough t o f ool a met al det ect or looking f or met eorit es. Couple t hat wit h a climat e t hat is hard on met al, and I wouldn’t have much luck here! (MT ) What is your f avorit e met eorit e in your collect ion? (T L) I have several I like. I am very t aken wit h t he weird cryst alline st ruct ure of It qiy. I own a small piece of Honolulu, one of t wo met eorit es t hat f ell in my st at e. Lunar and Mart ian planet aries are also f avorit es. And I have several waf er t hin slices of Esquel, and ot her pallasit es. (MT ) What is your f avorit e overall if it is not t he one above? (T L) Any of my t hin sliced pallasit es: Quinjingue, Imilac, Pallasovka, Krasnojarsk, Esquel… (MT ) What makes t hese of special int erest ? (T L) I f ind t hem beaut if ul, aside f rom t he obvious scient if ic int erest . (MT ) What met eorit es are current ly on your wish list ? (T L) Any pallasit es I don’t have now! I’d love t o be able t o af f ord a palm-sized slice of t ranslucent Esquel, but don’t have t hat t ype of f ree cash. (MT ) What met hods have been most successf ul in building your collect ion? (Buying at shows, f rom dealers by mail, auct ions on t he web, t rading… et c) (T L) I’ve only been able t o at t end one show, but came away f rom it wishing I could go t o more. Most of my purchases have been f rom ebay, alt hough as I have become more discriminat ing, if I want a part icular met eorit e I have more luck looking at individual dealers’ st ock. Somet imes I will sell of f a smaller piece if I upgrade, but since I concent rat e on small pieces t o begin wit h, I don’t get t o do much t rading. On a visit t o t he Brit ish Nat ural Hist ory Museum; Dr. Caroline Smit h is kindly allowing me t o look at some of t he undisplayed met eorit e collect ion. (MT ) Do you also collect relat ed mat erials like impact glasses, breccias, melt s, t ekt it es, shocked f ossils, nat ive iron rocks et c? (T L) Yes; several years back I got a select ion of impact breccia and glass f rom Germany in exchange f or some spare impact it es, and have occasionally bought t ekt it es and ot her impact relat ed mat erial. I part icularly like a t ranslucent piece of LDG I own. (MT ) Do you prepare any of your own specimens? (cut , polish, et ch, et c.) (T L) No; t hat ’s one aspect I’ve never got t en int o. T he only preparat ion I do is t o t ry t o kill lawrencit e disease wherever it st rikes. (MT ) Have you had t o t ake any special measures t o prot ect t hem f rom t he environment ? (T L) All but 2 or 3 of my met eorit es are st ored in gem jars, membrane boxes, or Riker mount s. T his seems t o prot ect t hem f rom t he worst ravages of our salt air, alt hough t he at mosphere here has been hard on my et ched irons; I’ve declared a morat orium on buying irons unless I have a nearly f oolproof way of prot ect ing t hem. (T L) I am a big advocat e of get t ing kids int erest ed in science, and met eorit es are a good t angible way t o get t hem st art ed. I’ve given several t alks locally about met eorit es t o element ary and middle school st udent s, and once t hey realize t hat t he rock t hey are handing around came f rom out er space, t hey usually are f ascinat ed and t he quest ions f ly. I keep some small specimens of unclassif ied NWA met eorit es handy t o give out t o int erest ed kids, and have one on my desk at work. Recent ly I loaned out some of my lunar met eorit es t o a geologist at t he UH Inst it ut e f or Ast ronomy f or comparison st udies on moon dust f rom t he Apollo missions.
