"The basaltic shergottite Northwest Africa 856 (NWA 856): Petrology and chemistry" by: A. Jambon*, J. A. Barrat, V. Sautter, Ph. Gillet, C. Göpel, M. Javoy, J. L. Joron and M. Lesourd
[Meteoritics & Planetary Science 37-9 (September 2002) © Meteoritical Society, 2002. Printed in USA.] The abstract is on the following web page: http://www.uark.edu/~meteor/abst37-9.htm#jambon Congratulations to the authors. This paper sets the standard for an all-inclusive, cross-discipline study of an individual [martian] meteorite. You'll want to get your hands on a copy of the latest issue of M&PS. Here's a sample from the abstract: "On the basis of grain size, pyroxene zoning and composition, abundance of silica inclusions associated with maskelynite, trace element abundances, REE pattern and oxygen isotopes, pairing with NWA 480 is excluded." [also excluded was Los Angeles] "The similarity with Shergotty and Zagami is striking." [but not similar to Los Angeles] "The only significant differences are a larger grain size, a greater abundance of silica and melt pockets, a slightly more restricted range of pyroxene compositions and the absence of significant mesostasis."
