柯石英

以柯石英榴辉岩为代表的超高压变质岩可能是具有元古代基底苏鲁微大陆块前缘俯冲到70～100km或更深的地方，遭受超高压变质作用形成的。

The ultrahigh-pressure metamorphic rocks , represented by coesite-bearing eclogite , may have been formed as the former edge of the Su-Lu micro-continent with Proterozoic basement had subducted to 70 ~ 100km or more deep and suffered ultrahigh-pressure metamorphism .

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 .
