Petrology and crystal chemistry of poikilitic anorthositic gabbro 77017Aspects of mineralogy are considered, taking into account the occurrence and the characteristics of plagioclase, pyroxene, and olivine. Attention is also given to oxides, opaque minerals, and glass components. Questions regarding the temperature of formation and the origin of the considered lunar poikilitic rocks are discussed. It is pointed out that the presented hypothesis may not be applicable to other poikilitic lunar rocks.
