Chassigny
Martian Meteorite (dunite), Chassignite Prototype
Fell, 3 October 1815; 4 kg

After detonations, one stone was recovered and stored for posterity. Chassigny is compositionally dominated by olivine (Fa32) but contains several minerals indicative of its original mafic/ultramafic origins in a moderately hydrous and moderately oxidized environment. These features are significantly different from most igneous, differentiated meteorites ['achondrites'] apparently from several airless worlds (including Vesta and the moon). Augite, chromite, rutile, spinel, and several other accessories to the dominant olivine bespeak an original origin at some depth in a magma chamber. Amphiboles (e.g. kaersutite) and the particular sulfides (pentlandite, pyrite, marcasite) are much more typical of earth-like environments than of the original parent bodies (OPB) of most achondrites. Chassigny, however, is not an earth rock. Its oxygen isotope ratios make it a member of the Shergotty-Nakhla-Chassigny (SNC) Clan. And the SNC Clan are Martian Meteorites - a conclusion first established when it was discovered that several of the meteorites contained small gas inclusions virtually identical to those detected by the Viking Landers in the Martian soils.

Chassigny was the first Martian meteorite to be discovered and is now regarded as the prototype for three martian 'chassignites.' The chassignites are only a small subset of the nearly 150 martian meteorites identified by 2015. Some shock features and melt inclusions appear to be derived from (at least one) impact events. Curiously enough, however, while the chassignites appear to have been derived from deep beneath the Martian crust, they are generally not as shocked as some of the Martian shergottites produced nearer to the Martian surface.
