Definition
Shergotty is a 5-kg Martian meteorite discovered in 1865 in Shergotty (now Sherghati), India. It also names a subgroup of the SNC meteorites, the shergottites, representing 78% of the Martian meteorites. Its age has been dated to ca. 165 Ma, although initially Pb-Pb dating indicated an age as old as 4.3 Ga. Shergottite source craters have been identified on young terrains in Tharsis and Elysium provinces. Petrologically, Shergotty is a basaltic sample (containing pyroxene and plagioclase but no olivine or chromite), enriched in trace elements.
