augite 英/ ???ɡa?t / 美/ ????d?a?t / - 1
地球科学 辉石 Olivine and chromite crystallized initially, low-Ca pigeonite formed and poikilitically enclosed cumulus phases, followed by continuous crystallization of augite and then plagioclase, finally more evolved phases such as whitlockite, ulv? spinel, and ilmenite crystallized. L-S型陨石相同的岩相学、矿物化学及REE地球化学特征符合单一岩浆储库的渐进分离结晶模式:即橄榄石和铬铁矿发生初始结晶后,低钙辉石形成并嵌晶包裹堆积相,持续的结晶包括普通辉石的形成和随后斜长石的结晶,最后是演化晚期的矿物如白磷钙石、钛铁晶石和钛铁矿的晶出。 普通辉石

The results show that garnets in the ore deposit are mainly andradite-grossularite and augites are mainly diopside. The skarns in the Jiama ore deposit belong to typical calcic skarns. 测试结果表明,矽卡岩中石榴子石以钙铁榴石-钙铝榴石为主,辉石以透辉石为主,甲玛矿床矽卡岩属于交代矽卡岩中典型的钙矽卡岩。
