Shergottites-Nakhlites-Chassigny

Twenty-six meteorites are believed to be martian rocks. This group was formerly referred to by the acronym SNC (for Shergottites, Nakhlites, and Chassigny). However, this designation is no longer comprehensive, and the simple... 

Source Lodders (1998) Shergotty and QUE94201 are basaltic shergottites, ALH 77005 is a lherzolitic shergottite, ALH 84001 is an orthopyroxenite, Nakhla is a nakhlite, and Chassigny is a chassignite. Analytical uncertainties are Is deviations for multiple analyses. 

Sheroottites. The shergottite meteorites are a rare class of meteorites which consist essentially of pyroxene and maskelynite. Their composition, petrography, age and gases trapped within the fabric of the meteorite have led to a widespread idea that these meteorites, and the related nakhlites and Chassigny meteorites, were ejected from Mars,...

The nakhlites and Chassigny could still come from a single event, given their similar crystallization ages and indistinguishable cosmic-ray exposure ages. However, they are unlikely to come from the same event that ejected the shergottites (Treiman 1995).
