云母石

黑云母、榍石、锆石、锡石、金红石、黑钨矿、白钨矿和钨铁铌矿等是讨论的重点矿物，它们可用于判别花岗岩的成矿能力。

Biotite , titanite , cassiterite , rutile , wolframite , scheelite and wolframoixiolite are essentially useful minerals in clarifying the ore-forming potential of granites .

其中麻粒岩主要出露于佛坪县城南约500m河东岸，呈条带状和透镜状产出，其矿物组成以透辉石、斜长石、角闪石、黑云母及石榴子石为主。
