Mineral constituents consist mainly of jadeite, aegirine-augite, magnesio-riebeckite, winchite, magnesio-hornblende, actinolite, quartz, albite, rutile and sphene.

主要组成矿物为硬玉、霓辉、、蓝透、角、阳起、英、钠长、金红和榍。

In the ocean basin spreading stage of Middle Silurian, it formed a increase metamorphic charateristics with lotrite facies→low green schist facies→hornblende facies.

中志留世末洋盆扩张阶段，形成葡萄、绿纤相→低绿片岩相→角岩相递增变质特征；

中志留世末洋盆扩张阶段 ,形成葡萄、绿纤相→低绿片岩相→角岩相递增变质特征 ;

, On the Mohs hardness scale, zoisite and hornblende (or tschermakite) have hardnesses about about 6½, whereas corundum has a hardness of 9.

比如，黝帘和角（或者钙）摩氏硬度为6.5，而刚玉则达到9。
