SpletThe Tissint meteorite is a picritic basalt from Mars that is about 600 m.y. old and took about 1.1 m.y. to get here (based on cosmic ray exposure). It is classified as a depleted olivine-phyric shergottite. Tissint is an olivine rich basalt with two generations of olivine. Large, rounded olivine megacrysts appear to be more mafic than the rock. SpletThe Martian volatility trend is consistent with 7 wt% S in its core, which is signiﬁcantly lower than that assumed in most core models (i.e., >10 wt% S). Furthermore, the occurrence of ring-woodite at the Martian core-mantle boundary might have contributed to the partitioning of O and H into the Martian core. Corresponding author.
