| 内容記述 | A petrologic study of crystalline lithic clasts from feldspathic breccia 67975, collected on the rim of North Ray crater at the Apollo 16 site, is presented. A light gray group has been identified as granulitic breccias, and a dark gray group has been identified as feldspathic microporphyritic melt breccias. It is suggested that complete homogenization of the minerology of the granulitic breccias may have been prevented by their incorporation into the 67975 fragmental breccia, and that metamorphism of the clasts may have been interrupted by this breccia forming event. |
