šergoti

šergoti

One of the three types of meteorites from Mars (the SNC meteorites). The type is named after the Shergotty meteorite, which fell in India in 1865. Basaltic shergottites consist mainly of plagioclase and pyroxenes. They are fine-grained and probably formed as volcanic lava flows or shallow intrusions. Lherzolitic shergottites are related to the basaltic shergottites but are coarser grained, have larger amounts of olivine, and are considered to be cumulate rocks.
