| 摘 要： | 河南桐柏龟山组由一套绿片岩相至角闪岩相的变质岩系组成,主要岩性为二云石英片岩、斜长角闪片岩、白云质大理岩及硅质岩。根据龟山组稀土元素和微量元素的研究,认为其原岩为基性火山岩、火山碎屑岩及砂泥质沉积岩;该组岩石形成于过渡壳性质的弧后盆地环境,为一套有利于成矿的火山沉积建造。

| Abstract: | The Guishan Group of Tongbai developed in Henan Province was composed of a set of regional metamorphic rocks from greenschist facies to hornblende facies. Its lithological characters was mainly muscovite biotite quartz schist, anorthosite hornblende schist,dolomite marble and silicolites. After the working on REE and trace elements, the author found that the primary rocks of them mainly belong to basic volcanic rock and volcano clastic sedimentary formation, and a few of them are part of tophaceous sediment. The Guishan Group was a suit of volcano sedimentary formation to the advantage of ore forming which developed in arc back basin in the transition type crust. |
