The zircon mineralogy and chronology of the eclogite show that a lot of primary inclusions of omphacite,phengite,garnet,bariosite etc.occur in the zircons,so the zircon should be formed during eclogite facies metamorphism.SHRIMP dating for zircons suggests the age of eclogite facies metamorphism range from 230 to 243Ma.

锆石矿物学和SHRIMP年代学研究表明，榴辉岩锆石中含有大量的绿辉石、多硅白云母、石榴子石、冻蓝闪石等矿物原生包裹体，锆石为榴辉岩相变质作用过程中从形成的变质锆石，锆石SHRIMP U—Pb年龄在230～243Ma之间，代表榴辉岩相变质作用的时代。

The author analyses and studies in detail through X-diffraction test of up to date special reserver samples and find that 1:1 regulation mix layers of corrensite and allevardite exists in some piecis of the eroded volcano tuff 's sandstone at the same time, and can appear continuously in a large amount In a certain limit, authors point out characteristic of corrensite and allevardite in this district and it's mining to genesis mineralogy that related to stratum water and trace element geochemistry characteristics.

作者通过最近的海拉尔盆地特殊储层样品的X衍射试验分析和详细研究，发现1：1规则混合层矿物柯绿泥石和钠板石同时存在于海拉尔盆地含火山凝灰质蚀变储层或非储层的某些井段中，而且在一定范围内的岩石孔隙中可以大量持续出现，指出了本区柯绿泥石和钠板石的组合特征，结合该区地层水和微量元素地球化学特征以及重砂特征等研究了柯绿泥石和钠板石的成因矿物学意义和其它石油地质意义。
