| 1 | This paper studies the characteristics and geological significance of mineralizing microcline in Wulashan gold ore field. | |
| 2 | This next sample that I will pass around is a microline mineral, also called amazonite. | |
| 3 | Cumulate plagioclase appears abruptly at the base of the F unit , which rests on an erosional disconformity. | |
| 4 | A hard, dense, dark volcanic rock composed chiefly of plagioclase, pyroxene, and olivine, and often having a glassy appearance. | |
| 5 | This kind of plagioclase is unique for the gabbroic rocks, not phenocrysts for any kind of granitic rock. |
