To date, all but one of the 86 recovered martian meteorites exclusively show an igneous origin. The meteorite Northwest Africa (NWA) 7034, also called “Black Beauty", and associated paired meteorites are the only examples of polymict breccias consisting of igneous and sedimentary clasts, and impact-derived components likely derived from the early martian regolith. In this talk, we will discuss a large impact melt clast, which displays a unique texture and composition. Various petrographic evidence suggest that this clast likely represents the first martian sample with crustal composition as measured by rovers.
