Lithology: Fine-grained, moderately sorted sedimentary rock likely deposited in a lacustrine setting; a sulfate-bearing fine sandstone. The rock is rich in weakly-hydrated Mg-Fe sulfate. Small amounts of FeMg-clay minerals, possible carbonates, and hydrated silica or Al-clay minerals were also detected. The rock is cut by scattered veins and patches of Ca sulfate, likely anhydrite, whereas the sulfate in the rock matrix is more magnesian. Fluorescence signals are consistent with a mix of aromatic compounds, and are associated with the calcium sulfate patches.
