[1] The Nili Fossae region located on the northwestern quadrant of the Isidis Basin, Mars, displays superb exposures of bedrock outcrops that reveal mineralogy and composition of the crust. Previous work has shown that this region exhibits the largest exposures of olivine-dominated rock units on Mars. Visible-infrared imaging spectrometer data acquired by OMEGA were calibrated to surface reflectance and analyzed to determine surface mineralogy. The dominant minerals identified are iron-bearing… Expand

Seeing through the dust: martian crustal heterogeneity and links to the SNC meteorites
TLDR
It is possible to infer, even through the veil of dust, that the SNC meteorites have mineralogic affinities to major volcanic provinces on Mars and are therefore truly representative of the heterogeneity observed on the surface of the "red planet". Expand

Olivine and Pyroxene Diversity in the Crust of Mars
TLDR
Olivine- and HCP-rich regions are found in deposits that span the age range of geologic units, however, LCP- rich regions are find only in the ancient Noachian-aged units, which suggests that melts for these deposits were derived from a mantle depleted in aluminum and calcium. Expand
