[meteorite-list] Zaklodzie and TKW's
Thanks Macrin, Very interesting regarding Zaklodzie! The next question that soon comes in mind: was this unweathered portion of the meteoirite the one that was analyzed for its type determination/classification ?? Thanks for the TKW's. My data come from A to Z. The Met. Bull. data (I simply forgot looking) apparently should be the only reliable so far. Set aside for correction of the next edition (Mike ?), though A to Z often mentions higher weights (respectively 999+ kg (Brahin) and 300+ kg (Chinga). Has somebody (from Russia ?) more recent data on these two TKW's ? For example, I have heard from a semi-reliable (but local!) source that Gibeon's TKW is...over 120 tons! (real competitor for Campo!). Best, Zelimir A 14:14 14/01/2009 +0100, Marcin Cimala - PolandMET a écrit : Excellent pics of the main mass Marcin! === Thank You :D I forgot about this photos for a while. 2 questions: 1) is the tan-white area containing the metal islands of eucritic type ? No This is just perfect example of weathering. Especially full slice but also main mass with his tiny white dot in center, showing very sharp zones of weathering approaching from outside to inside. So oryginaly Zaklodzie was perfect WHITE! Thats why this last full slice is soo importand becouse contain fresh, not weathered material. In the remaining main mass ~5kg there is propably no more of this material deep inside specimen. Another interesting feature in full slice is top right area above iron core. There are several graphite globules in iron ! 2) From which source do you know that the TKW of Brahin and Chinga are respectively 823 Kg and about 200 Kg ? = Met Soc website say http://tin.er.usgs.gov/meteor/metbull.php Chinga TKW 209.4 kg Brahin TKW 823 kg -[ MARCIN CIMALA ]-[ I.M.C.A.#3667 ]- http://www.Meteoryty.pl marcin(at)meteoryty.pl http://www.PolandMET.com marcin(at)meteorite.pl http://www.Gao-Guenie.com GSM: +48 (793) kosmos [ Member of Polish Meteoritical Society ] __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list Prof. Zelimir Gabelica Université de Haute Alsace ENSCMu, Lab.

Thanks Macrin, Very interesting regarding Zaklodzie! The next question that soon comes in mind: was this unweathered portion of the meteoirite the one that was analyzed for its type determination/classification ?? I dont know this, but If I could be scientist, I will like to use this fresh part for tests. Im sure that not for all tests this was importand how weathered is material. But I know that this white center was well tested. This large iron in center also was etched. Thanks for the TKW's. My data come from A to Z. === You know, TKW is not most importand here and for sure impossible to get it even close to real weight. With large finds like this we know its hundreds of kilos, so better mark it as TKW=large :) -[ MARCIN CIMALA ]-[ I.M.C.A.#3667 ]- http://www.Meteoryty.pl marcin(at)meteoryty.pl http://www.PolandMET.com marcin(at)meteorite.pl http://www.Gao-Guenie.com GSM: +48 (793) kosmos [ Member of Polish Meteoritical Society ] __ http://www.meteoritecentral.com Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Zaklodzie and TKW's
That unweathered inner part of Zaklodzie had very distinct edges; I was also surprised to see the (relatively) huge metal blebs in the slices. I would think that there would be an area of most weathering closest to the exterior, and a more graduated progression as the elements slowly seeped into the interior, rather than a discrete 'core', which looked very eucrite-ish. Is there any chance that this was an anomalous piece of Zaklodzie with an inclusion? What created such a clear boundary?
