Abstract

Angrites are a relatively small group of ancient basaltic achondrites (21 currently recognized stones, including pairings). They have a remarkable volatile poor, silica undersaturated composition and a characteristic mineralogy of Ca-rich olivine, Al-Ti bearing pyroxene and anorthite. We are interested in using the light element chemistry of this group to study their magmatic history. Here we report on updated carbon and nitrogen abundance and stable isotope data from a suite of 8 angrites analyzed by stepped oxidation.
