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

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!
