摘要: THIS unique olivine-clinopyroxenite meteorite (angrite) has been intensively studied first because it contains evidence of the existence extinct radionuclides1,2 and second is richest in Ti Ca therefore most similar to lunar rocks3. In addition, suggested that mantle may be composed clinopyroxenite4. Surprisingly, spite this interest, no analyses Angra dos Reis (stone) minerals have yet published, data presented here remedy deficiency.
