绿帘石

绿帘石有时相当显著。

当俯冲深度接近50km，俯冲陆壳岩石中大量低级变质含水矿物（如绿泥石、绿帘石、阳起石）会脱水并从俯冲陆壳逸出形成流体流。

When the subduction depth is near 50km , the voluminous lower grade metamorphic hydrous minerals ( e.g. chlorite , epidote , actinolite ) undergo dehydration forming an aqueous fluid flux .

当实验温度为680C时，黑云母与斜长石发生脱水熔融和部分熔融，转换成白云母、绿帘石、铁尖晶石、石英等物质成分；

At the temperature of 680 ℃, biotite and plagioclase became dehydrated-melted and partially melted , transformed into muscovite , epidote , hercynite , quartz , etc. ;

风化绿帘石和绿泥石很难区分。

It becomes difficult to discriminate between weathered epidote and chlorite .
