硬柱石

黝帘石-蓝晶石-柯石英组合的出现指示大别山榴辉岩的压力上限未达到硬柱石的稳定区域，其形成压力不会超过4.0～4.5GPa。

The occurrence of zoisite + kyanite + coesite assemblage indicates that the upper pressure limit of eclogite in the Dabie Mountains does not reach the stability field of lawsonite , and therefore could not exceed 4 . 0-4 . 5 GPa .

绿帘石可以稳定到＞3.5GPa，在4GPa时转变成硬柱石；

Epidote is stable up to more than 3.5 GPa and transform into lawsonite at 4.0 GPa .

电子探针分析表明，蓝闪石主要为铁蓝闪石和青铝闪石，硬柱石为较典型的硬柱石。

Microprobe analysis suggests that glaucophane is mainly ferroglaucophane and crossite , while lawsonite is relatively typical one .
