Angrites are a rare group of achondrites notable for their critical silica undersaturation, lack of shock metamorphic features and ancient crystallisation ages. They are sub-divided into plutonic or basaltic angrites on the basis of their inferred petrogenesis. Similar studies to those already carried out on HEDs and shergottites could be used to shed light on magmatic processes on the angrite parent body (APB). Here we present results from carbon and nitrogen stepped combustion experiments on the plutonic angrites Angra dos Reis (AdoR) and NWA 2999, and the basaltic angrite D’Orbigny.
