Martian dunite NWA 2737: Integrated spectroscopic analyses of brown olivine

Received 5 October 2007; revised 13 December 2007; accepted 6 March 2008; published 18 June 2008. [1] A second Martian meteorite has been identified that is composed primarily of heavily shocked dunite, Northwest Africa (NWA) 2737. This meteorite has several similarities to the Chassigny dunite cumulate, but the olivine is more Mg rich and, most notably, is very dark and visually brown. Carefully coordinated analyses of NWA 2737 whole-rock and olivine separates were undertaken using visible and near-infrared reflectance,
