| 摘 要： | 河南省嵩箕地区登封群变质杂岩，原岩为一套造山带和岛弧的中基性、少部分为酸性的火山岩组合。其中郭家窑组为基性，常窑组、石牌河组逐渐向酸性火山岩过渡，石梯沟组属正常沉积岩系列。该群微量元素丰度值与地壳克拉克值相比，普遍偏低，其中Ｒｂ、Ｓｒ、Ｂａ、Ｆ、Ｌｉ等元素明显偏低。

| Abstract: | The metamorphic complex of the Dengfeng Group in the Songji area,Henan. Whose protolith was a suit of the intermediate-basic(a little acid)volcanic rock assemblages of the orogenic belt and island are. The Guojiayao Formation in them is the basic volcanic rock,and theChangyao and Shipaihe Formations transit gradually to the acid volcanic rock. The abundancevalue of the microelements in the Dengfeng Group is universally lower than the clarkes of theearth crust,in which the elements Rb,Sr,Ba,F and Li are lower obviously. |
