柯石英榴辉岩

本文报道了一项中美合作研究的新进展：笔者于1992年在河南省新县发现了柯石英榴辉岩。

Coesite eclogite was discovered by the authors in Xinxian County , Henan Province , central China in1992 .

N2包裹体仅见于含柯石英榴辉岩，而高盐度流体包裹体则几乎存在于所有的榴辉岩和硬玉石英岩中。

Pure N 2 inclusions have been observed only in fresh coesite bearing eclogites , whereas highly brine inclusions exist almost throughout the ultrahigh pressure ( UHP ) metamorphic rocks .

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 .

本文报道了大别山东南部安徽石马地区柯石英榴辉岩组合和黄镇地区石英榴辉岩组合的全岩及单矿物的氢氧同位素特征。

The hydrogen and oxygen isotope compositions of single minerals and whole-rock were measured for coesite-bearing eclogite at Shima and quartz-bearing eclogite at Huangzhen in southeastern Dabie .

大别山太湖县石马超高压榴辉岩相岩石可分为两类：（1）以柯石英榴辉岩（已退变质）为代表的硅饱和岩石；

Ultrahigh-pressure eclogite-facies rocks in the proximity of Shima , Taihu County in the Dabie mountain are divided into two different types : ( 1 ) silica-saturated rocks , represented by coesite-bearing eclogite ( retrograded );

利用拉曼光谱学和费氏台方法对若干地区超高压榴辉岩中柯石英和榴辉岩中石英出溶体的超显微构造特征进行了研究。

The studies on ultra-microstructure characteristic of quartz exsolution in eclogite and coesite in UHP eclogite of several localities are done with the appliance of laser Raman spectroscopy and U-stage .
