    Info: The Martian meteorites of this group are named for Nakhla, a fall that occurred in El Nakhla, Egypt, in 1911. The nakhlites are clinopyroxenites, displaying a sugary, fine-grained texture. They consist primarily of green cumulate augite crystals with minor olivine in a very fine-grained mesostasis.This mesostasis is composed of plagioclase, alkali feldspar, pyroxenes, iron-titanium oxides, sulfides and phosphates. Traces of pre-terrestrial aqueous alteration products are present in the form of hydrated minerals, e.g. amphibole, clay minerals similar to iddingsite or smectite, and carbonate and sulfate salts. Some researchers have proposed that the presence of these hydrated minerals in the nakhlites, in addition to concentrations of water-soluble ions such as Cl, K, Na, and Ca, suggests that they resided in an environment in which liquid seawater was present for some time, perhaps inside of an ancient Martian ocean.
