Orthopyroxenite

Edit links
From Wikipedia, the free encyclopedia
ALH 84001 is an extraterrestrial example of an orthopyroxenite. It is an achondrite meteorite from Mars.

Orthopyroxenite is an ultramafic rock that is almost exclusively made from the mineral orthopyroxene, the orthorhombic version of pyroxene and a type of pyroxenite. It can have up to a few percent of olivine and clinopyroxene. If it contains between 5 and 40% olivine, it is an olivine orthopyroxenite. If it contains over 40% olivine and orthopyroxene, it is a harzburgite.

This ternary diagram shows the orthopyroxenites as a function of olivine, clinopyroxene and orthopyroxene abundance.

Orthopyroxenites can also occur on other planets. ALH 84001 is a Martian meteorite that can be classified as an orthopyroxenite. It is the only meteorite found with that composition and the only member of the Martian orthopyroxenite group of meteorites.[1]
