Dear Listees,

Our weekly auctions will start ending on ebay in less than 24 hours and some of them are still at the $0.99 starting price.
Do not miss a chance to make good deals and see http://search.ebay.com/_W0QQfgtpZ1QQfrppZ50QQsassZkayunwar

Let me just point out some special ones...

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130068728337 : a superb oriented Sokhote ALin shaped like a thumb!

http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=130068727936 : a 3.12g partslice of a very special EUCRITE, Sahara02501.
Recent analyses have been made on Sahara02501, showing that it can be considered as a 'big' sister of Nuevo Laredo (see hereafter extract of Jean-Alix Barrat's abstract)
A selection of our new analyses are shown normalized to Juvinas, a reference MG eucrite (Fig.1). The patterns of typical MG eucrites such as Bereba and Jonzac, are rather flat with a significant Cs and Rb enrichment. The patterns of NL eucrites (Nuevo Laredo, Lakangaon, Igdi, Sahara 02501) exhibit higher incompatible element concentrations, and Sr and Eu negative anomalies, in agreement with their more evolved compositions. (Note that high Ba and Sr abundances in Saharan finds are produced by alteration [9]). The Stannern trend eucrites (Stannern and Bouvante)are not only richer in in compatible trace element than the other eucrites, but their trace element patterns are clearly distinctive, with pronounced negative Be, Sr and Eu anomalies. As is the case for the MG-NL trend eucrites the behavior of alkali elements seems somewhat erratic, and has not yet been properly explained (fingerprints of impact processes? Mobility of alkalis during metamorphism?).

Thanks for watchoing and Good Luck!
