Abstract

The martian geological record comprises mafic-ultramafic volcanic activity showing physical and chemical commonalities with komatiite and ferropicrite magmatism on Earth. Given that terrestrial komaliites and ferropicrites locally host economically important Ni-Cu-PGE sulfide deposits, this thesis examines whether volcanism on Mars have led to similar mineralization. Emphasis is laid on examining the inventories of sulfur and precious metals in martian igneous systems, and the potential processes that favour the segregation and accumulation of precious metal-rich sulfides. The results suggest that Ni-Cu-PGE sulfide mineralization on Mars may have formed by the dynamic interaction of lava flows with sulfur-rich sedimentary substrates.
