Early results from the Mars Odyssey THEMIS have revealed, in high (20 to 100 km/pixel) spatial detail, the distribution of orthopyroxene- and olivine-bearing meteorite-like materials identified in MGS TES data [Hamilton and Christensen, 2003; Hamilton et al., 2003]. The presence of significant quantities of these mafic minerals is important not only to understanding the igneous history of Mars, and the possible origins of the Martian meteorites, but also to understanding the weathering regime(s) to which they have been subjected since they were exposed. These sites now have nearly complete THEMIS coverage (day and night) by the infrared subsystem, and greater than 50 percent coverage by the visible subsystem. We will present updated descriptions of the distribution, visible and infrared spectral characteristics, and thermophysical characteristics of these sites as observed by THEMIS, and discuss how these properties provide information on the history of these materials. Additionally, we will discuss how we have used THEMIS data to confirm TES-based identifications of meteorite-like lithologies in spatially small sites. [1] Hamilton, V. E. and P. R.
