主 题：meteorite chondrite inclusion solar nebula condensation crystallization alteration.
摘 要：In three polished thin sections of Yamato 791717 (CO3), fifty\|five Ca, Al\|rich inclusions were found, which include two hibonite\|bearing, eight melilite\|rich and forty\|five spinel\|pyroxene inclusions. Based on the petrography and mineral chemistry of the inclusions, it is proposed that the melilite\|rich inclusions and spinel\|pyroxene inclusions condensed in the solar nebula, and the hibonite\|bearing inclusions crystallized from melts. The heavy alteration of the inclusions in Yamato 791717, which probably took place under a very oxidizing condition in the solar nebular, is also confirmed.
