Meteorite-Times Magazine Witnessed Fall: Yurtuk, Ukraine by Martin Horejsi Like

An April 1936 Witnessed Fall: Yurtuk, Ukraine

A Double Hammer Stone! Borne from Impact on an Asteroid. Hammered a House here on Earth.

To behold a howardit e is t o gaze upon t he physical manif est at ion of t he past and present dynamic processes of our solar syst em. Alt hough howardit es command some of t he highest prices of t he HEDs, essent ially t hey are just ast eroid dirt classif ied as a proport ional mix of t wo or more arist ocrat ic met eorit es.

What would you get if you tossed a eucrite and a diogenite in a blender? According t o met eorit e dealer Blaine Reed, you would get a howardit e. Howardit es are samples of t he soil on an ast eroid made f rom surf ace eucrit es mixed wit h subsurf ace diogenit es as well as a breccia of t he impact or t hat brought t he f ormer t wo t oget her. Of t en t he basalt ic ast eroid was hit by a chondrit e so essent ially a howardit e is t he result ant polymict breccia of t he most popular achondrit es and chondrit es pulverized and recement ed int o a rare met eorit e class named Edward Charles Howard (1774 -1816) a Brit ish chemist described as â&#x20AC;&#x153;t he f irst chemical engineer of any dist inct ion. Howard was t he f irst t o not ice t he presence of a nickel-iron alloy across many dif f erent

met eorit es. T husly met eorit es are more chemically similar t o each ot her t han t hey are t o t he eart h rocks.

T he common published descript ion of t he eart hly arrival of Yurt uk is t he f ollowing: In Mikhailov dist rict , Lubimov, Ukraine, at about 1:00 in t he morning on April 2, 1936, one st one of 509g f ell t hrough t he roof of a house. Several more pieces were picked up out side t he house including one of 51.5g. T he t ot al known weight of Yurt uk is 1.472kg. Alt hough t he t ot al known weight is a palt ry 1472 grams, t wo t hings st and out . First , t he T KW is act ually f airly large as f ar as howardit es go, and second, t he ent ire f all cont ains an unknown number of specimens.

Where do howardit es come f rom? Well, t hey are basically t he soil of an ast eroid creat ed t hrough an impact mixing process described above. Essent ially, t he upper lef t of t he diagram t urns int o t he lower right . It â&#x20AC;&#x2122;s act ually a lit t le more complex and f ascinat ing t han t hat so f or a richer explanat ion, please consult t he howardit e ent ry in O. Richard Nort onâ&#x20AC;&#x2122;s wonderf ul book Rocks f rom Space.

[diagram ref erence: Labot ka, T. C. & Papike, J. J. Howardit es: Samples of t he regolit h of t he parent body. Lunar and Planet ary Science Conf erence, 11t h, Houst on, T X, March 17-21, 1980, Proceedings. Volume 2, 1980]

Except f or t he mid 20t h cent ury f all dat e, Yurt uk is a rare class of rare classes, a hammer st one of very small t ot al known weight and low dist ribut ion. But Yurt uk, and all howardit es f or t hat mat t er, are act ually “Double Hammers” because t hey are t he of f spring of a cosmic hammering bef ore mat uring t o t he point of cont inuing t he circle of violence here on eart h. T he beaut y of t he howardit e is wit hin t he anger f rom which it was creat ed. One of t he t ruly inspiring aspect s of howardit es is f ound wit hin it s mat rix. T he gorgeous int ricacies of t he howardit e’s int erior mat ches t he excit ement of any good junkyard. Rich wit h bit s and pieces of past lives, t he howardit e is a reservoir of geologic jewels some more obvious t han ot hers. Not e t he green gem in t he cent er of t his pict ure. Looks t o me like t he hubcap of f an old diogenit e.

T he f usion crust on Yurt uk, like any good calcium-rich achondrit e, is a glossy jet black f ilm providing about t he most cont rast possible bet ween t he int erior and ext erior of a met eorit e: liquid t ar on snow. For many, t he Joy of Fusion Crust is f ound on t he lesser weat hered hot desert f inds, but lest we f orget what unt ouched crust looks like. Impossible t o mist ake. Hard t o explain. To misquot e somebody, “Talking about f resh f usion crust is like dancing about archit ect ure.” Trust me. You’ll know it when you see it . But you might not believe it ’s real.

Mouseover t he above pict ure t o see a color-invert ed version. Swiping your mouse on an of f t he image allows your eyes t o more quickly f ind int erest ing f eat ures t hat eit her image in isolat ion would not highlight . Yurt uk, like most howardit es provides a pot pourri of met eorit es all embedded wit hin one. T he cut f ace above exhibit s classic howardit e

t ext ure which act ually means it is a diverse conglomerat e of eucrit e, diogenit e and chondrit e f ragment s. I like t o believe t hat t he large dark likely condrit ic mass just right of cent er is act ually a piece of t he Ensisheim parent body. A st ret ch you t hink? Possibly, but consider t hat you just cont emplat ed t his concept f or t he f irst t ime in your lif e. How of t en does t hat happen in t his column? For me, Yurt uk was one t hose highly collect able met eorit es t hat had such a degree of availabilit y sat urat ion t hat I didn’t t ake it as seriously as I should have. T hen one day, I lit erally woke up one morning and t hought t o myself , “Why have I not bought t he great piece of Yurt uk list ed on a part icular dealer’s websit e?” Lat er t hat day, af t er making an of f er f ollowed by a humble explanat ion t o t he dealer as t o who was emailing him (silly me.

Meteorite-Times Magazine Cleaning Meteorites by Jim Tobin Like

T his mont h is going t o be kind of a weird mix of t opics. I may even disappoint a f ew people by doing somet hing I rarely do and t hat is not revealing a secret . First , it came t o my at t ent ion by an int erest ed reader of a past art icle f rom a couple mont hs ago t hat I had never writ t en in Met eorit e Times t hat my lit t le book on Tools and Techniques f or Cut t ing and Preparing Met eorit es was f inished. I had made a post t o t he met eorit e list but never here. So anyone int erest ed in learning a lit t le about lapidary work as it relat es t o met eorit es you can get a beginners course by reading my book. It is available direct ly f rom me. It is short enough t hat I am print ing it myself and binding it in a convenient coil binding, so it will lay f lat when you are working. Just drop me an email t o order it f or $12 plus $6 shipping. Boy, I am glad t o be done wit h t hat commercial. T here have been quit e a f ew emails lat ely on t he list about cleaning met eorit es. Well, I have developed a secret met hod t hat is so cont rollable t hat as you can see in t he f ollowing pict ures I can act ually remove 50 years of discolorat ion and bring out t he buried black f usion crust exact ly how I want . We had a bat ch of Gaos t hat needed cleaning and in a about t hree hours I had rest ored around a hundred or so t o a beaut if ul dark gray or black. When we had picked t hem out we t hought we were having t o t ake many t hat were broken. T he int ent was t hat I would grind and polish windows on t hose. But , when t hey were cleaned I f ound t hat all but about t hree of t he apparent breaks were in f act secondary f usion crust ed bumpy surf aces.

Maybe someday I will reveal t he process. I’m not sure but t here maybe some money t o be made of f ering t he cleaning t o ot hers. So it remains my lit t le secret f or t he t ime being. I hear some of t he chemical bat h met hods of cleaning and I just cringe. I would never put a st one in anyt hing. I have t rouble using dist illed wat er or 99% alcohol when cut t ing and f inishing t hem. Some irons get cleaned t ill t hey lit erally shine like new money. I guess it is a mat t er of choice wit h t he irons. I personally like irons t o be black or really if I can get t hem orange colored. T hen I am very happy. Just cleaned enough t o get t he dirt , soil and heavy rust of f t hem. T hat ’s t he way I like my irons. But , st ones if t here is a black f usion crust under t hat dirt I am working t o f ind it . I guess chemist ry is not f or me. I was corresponding wit h Anne Black recent ly and she asked me “What exact ly do you look f or and collect ?” T his is a quest ion t hat has been on my mind recent ly. I t hink at t his point I should begin t o bring some f ocus t o my collect ing. To show you how unf ocused it is, I have bought met eorit es just because I liked t he name. For example, Cocklebiddy an H5 f rom Aust ralia just sounds great t o me. I have bought met eorit es because a f riend or relat ive lives where t hey were f ound. Covert was f ound in Osbourne Count y, Kansas and my wif e’s sist er lives in Osbourne. I’m going t o t hink about narrowing in t he boundaries of what I will buy. I t hought about just get t ing new f alls. But , wit h increasing int erest and more successf ul recoveries I might f ind t hat an impossible challenge bot h f rom availabilit y and cost . Maybe, limit ing myself t o only met eorit es f alls in a cert ain port ion of t he world, or f rom a cert ain t ime f rame, say over f if t y years ago and older. T here would be a lot of opport unit y t here and I would not have t o buy any part icular one if it was t oo cost ly. Maybe, I should not be disciplined in my collect ing. Could I just be adding anot her layer of obsession on my obsession? Now f or a short int ermission wit h t his f ollowing pict ure of a spect acular met eorit e.

NWA 5080 is an amazing st one. It has been classif ied as a CV3. As a lover of primit ive chondrit es t his is just what I like t o spend t ime looking at under t he microscope. T here is no visible met al except wit hin a couple of chondrules. I not ed as I was f inishing t he surf aces, t hat t hey had t iny grains of met al wit hin t hem. Look f or a f ew slices t o be available on our websit e soon. As always, comment s, quest ions, and suggest ions f or t opics are welcome and you can send t hem t o me at jim@met eorit e.com unt il next mont h, goodbye. Please Share and Enjoy:

Meteorite-Times Magazine Spring Cleaning of my prior Planetarium Articles by Robert Verish Like

We need MORE IMAGES of meteorites that are on display in MUSEUMS and PLANETARIUMS A recent discussion regarding one of my previous Bob’s Findings art icles about t he Fleischman Planet arium at t he Universit y of Nevada, Reno, brought t o my at t ent ion t hat t rying t o f ind images of met eorit es and met eorit e displays in museums and planet ariums, even wit h search engines like Google, will yield very limit ed result s. It ’s my opinion t hat it is incumbant upon t hose of us t hat have visit ed world class collect ions, or have inst it ut ions wit h met eorit es on display near where t hey live t o record and place on-line images of t hese space-rocks, f or example, like Mart in Horejsi’s Oct ober 2006 “T he Accret ion Desk ” art icle. Especially, if you inf requent ly visit your local museum/planet arium/universit y, and it has a met eorit e display, you should record it wit h images.

Because t hat wonderf ul display is now, long gone. (Apparent ly somebody made t he “business-decision” t o remove t he display, because, “t he general public is not int erest ed in met eorit es”! ? T hen t here is t he problem of links t o pre-exist ing web pages of met eorit e displays going away due t o various reasons, such as, websit e revisions or changes in web-host ing. More of t en t han not , t he revised websit e is minus t he images of t he met eorit e displays! One way t o avoid t his problem is, if you have your own websit e, make your own web page. [Here is a good example: Henry Mendoza's Phot os on f acebook.] T hat way, even if you have a change in web-host ing, you can cont rol t he revising of your web pages. And t hat ’s exact ly what happened t o me. A change in service provider has brought about many broken links in some of my previous Bob’s Findings art icles, part icularly t hose involving met eorit e displays at planet ariums f or some reason. So, t his mont h’s art icle is a revisit of t hose met eorit e display image galleries.

Commemorating Christian Anger (1965-2009) compiled by Andrz ej S. Pilski Today I received an email f rom Harald St ehlik, saying t hat our good f riend Christ ian Anger had a very bad car accident on December 14, 2009, and he died. I am very shocked and sad, because Christ ian was not only a collect or but a f riend. Everybody knows how much f un we had when we were t oget her. We had also ot her privat e cont act and were real f riends. At f irst he t old me t hat he could not come t o t he Munich show because he had so many privat e problems in his mind. T hen he called me T hursday evening when I was in Munich, he decided t o come. So he was wit h us Friday evening at t he Fliegerbräu and st ayed in Munich t ill Sunday af t ernoon. He helped me t o bring some of my mat erial back int o t he car Sunday af t ernoon. T his was t he last t ime I saw him. True f riendship never ends… Hanno St ruf e

Munich 2009 — t he last meet ing Christ ian Anger, Hanno St ruf e, Dirk Hohmann, and his wif e (Phot o court esy of Hanno St ruf e) I just opened my mail and t he shock was immediat e: 51 emails ent it led “Christ ian Anger”! T his could not be some good news… Christ ian was, since t he f irst Ensisheim show, our “bright est light ”, et ernally smiling, a happy-t olive, cool, energet ic, joking, t easing, dancing, charming, f unny, “blast ing” person … but also one of t he most elegant , gent le, gracious, court eous guys. When he would show up in Ensisheim (he was among t he f irst t o come, f rom quit e f ar away), he had a pack of t hat “st rangely delicious” Aust rian beer f or us t o t ast e. But t here were also lot s of met eorit es in his bags, f or ambulant t rade and f or t he consignment room.

Ensisheim 2005 — Main mass of t he new f all f rom Niger/Nigeria Maigat ari-Danduma (Phot o court esy of Hanno St ruf e) T he superb 48g crust ed Maigat ari-Danduma he displayed t here f or sale as premium immediat ely went int o my collect ion, along wit h t he t ext describing it s weird quest t hat Christ ian had personally writ t en. Christ ian soon became our Brot her-Ensi-Met eorit e-Guardian.

Ensisheim 2005, ent hroning ceremony — Christ ian Anger (t op lef t ) is very happy t o be an Ensisheim Met eorit e Guardian! (Phot o court esy of Pet er Marmet ) And he t ruly deserved t his honor, not only t hrough his highly avid passion, compet ence, and love of met eorit es, but also f or his immense kindness, ent husiasm, and respect f or children and young amat eurs. And, oh yes, t he “Ensisheim Sat urday night f evers” could not have been “what t hey were” wit hout Christ ian’s “deep impact .”

Ensisheim 2005 — Part y t ime: Marc Jost , Zelimir Gabelica, Christ ian Anger (Phot o court esy of Pet er Marmet ) I also was so lucky t o meet him last November in Munich and we promised each ot her t o have a “great Ensisheim” again next year. My f riend, now t hat I st art realizing t his won’t happen, I promise you will never be f orgot t en. You are our f irst brot her t o have gone “somewhere over t here,” where you are now, I am sure, happy and in peace. I am right now planning f or your memory some special t reat next June and am sure all t he people t here will join, so as t o be so close t o you again. I will badly miss your “st range Aust rian beverage!” Zelimir Gabelica

Ensisheim 2005 — Harald St ehlik, Francesco Moser, Hanno St ruf e, Zelimir Gabelica, Marcin Cimala, Christ ian Anger on Sat urday evening (Phot o court esy of Hanno St ruf e) T his is very, very sad news. Christ ian will t ruly be missed, and my t hought s and prayers are wit h his f riends and relat ives. I knew Christ ian f or many years, and he used t o visit me at my home prior t o t he Ensisheim shows t o t alk about our f avorit e passion, and t o show of f or t o t rade rocks f rom space. He was one of t he kindest persons you can imagine, always f riendly and joking, wit h a big heart in t he right place. His passing away leaves a void t hat can’t be f illed. T here are a lot of anecdot es t hat come t o my mind when I t hink of Christ ian, t oo many t o t ell. One is a st ory around t he large main mass of HaH 173 which Christ ian t raded f rom me years ago. T he

is a st ory around t he large main mass of HaH 173 which Christ ian t raded f rom me years ago. T he int erior of t hat L6 was very f resh (W0-1), but t he mass had been buried in t he desert and it was t ot ally covered wit h a t ough caliche coat ing, making it an ugly duckling. However, Christ ian could see t he swan in it , and in weeks of met iculous work he manually removed all t he caliche—I didn’t recognize t he mass when he sent me a pict ure of it ! It really looked like a f resh f all as Christ ian had managed t o bring out t he original f usion crust which was hidden under t he caliche coat ing. Christ ian always had a great passion f or his met eorit es, and handled t hem wit h ut most care. Whenever he purchased a slice, he manually polished it so t hat he could also enjoy it under t he microscope. He was an exemplary curat or of his space rocks, second t o none. And he was a great guy, a real buddy. I had t he pleasure t o serve wit h him on t he IMCA Board of Direct ors. It was a pleasure t o have him as a f ellow Brot her of t he Ensisheim Met eorit e Brot herhood of Guardians, and – last but not least —as a f riend. Christ ian: your great sense of humor and your passion will sorely be missed. Godspeed! Norbert Classen President IMCA Inc.

Ensisheim 2006 — Christ ian Anger joking at t he annual Dinner Part y (Phot o court esy of Pet er Marmet ) “My name is Christ ian Anger. I live in Aust ria on t he hist orical soil of t he biggest ancient Roman legion camp called “Carnunt u.” On t his area are t wo villages now. One of t hem is my homet own Bad Deut sch-Alt enburg on t he most east ern f oot hills of t he east ern Alps called “Hundsheimer Mount ains.” It ’s about 50 km east of Vienna riverdown t he river Danube, near t he border t o Slovakia. My job is const ruct ion engineer f or road const ruct ions and pavement s.

My most f amous int erest s are amat eur ast ronomy, met eorit e collect ing (and a bit hunt ing and t rading and selling), as well as impact st ruct ures and met eorit e crat ers of our planet Eart h. T he root s of my int erest in met eorit es and relat ed mat t ers are in amat eur ast ronomy and collect ing some minerals when I was a boy. Twent y f ive years ago I got a small book about st ars and planet s. I t ook some old binoculars and looked, as recommended in t his book, up t o t he clear skies. I will never f orget t his moment . It af f ect ed my whole lif e. I also collect ed minerals at t his t ime. We have an ancient quarry here in my homet own. T here are some caverns, where I climbed int o t o pick up calcit es. My special int erest in ast ronomy is t he explorat ion of our solar syst em. I t ried t o get all t he inf ormat ion t he space probes sent back t o Eart h. But at t his t ime t here were not many books and magazines available in Aust ria. In 1993 I got my f irst int ernet account . T hen I was able t o get all t his inf ormat ion and images f rom t he planet s and t heir moons of our solar syst em. I loved t his st range and ext raordinary landscapes and especially t he impact crat ers. T his was t he point when my int erest in ast ronomy went int o t he science of met eorit e crat ers and impact st ruct ures, especially of our planet Eart h. T hen I want ed t o hold t he t hings, which caused such crat ers, in my own hand. Amat eur ast ronomy and mineral collect ing cumulat ed in my love t o met eorit es. My f irst met eorit e was a Sikhot e-Alin 49 g Individual. A very int erest ing one. It is 3/4 an ablat ed Individual and 1/4 a shrapnel. It is broken open on one side and you see a spiral shape like a t hread in t he int erior. From t his moment on, I was complet ely f ascinat ed about met eorit es and t his love is st ill growing. T he most beaut if ul experience in t his passion was my f irst own f inding of a met eorit e: an individual f rom a f resh f all – Moravka. My goal in collect ing met eorit es is t o have at least one specimen of every t ype (and subt ype) of met eorit es. I am t ype-collect or. I also collect t ekt it es, all t ypes of impact mat erials, and I have a small collect ion of met eorwrongs f or comparison purposes.” Christ ian Anger (About me)

We knew each ot her since last cent ury and I was of t en t alking wit h him at Gif horn/Munich/Ensisheim shows. One day, when I was in my home in Poland Erich Haiderer and Christ ian gave me a call t o get some advice f or Morasko-irons hunt ing.
