| 摘 要： | 阜平地区灰色片麻岩约占太古宙片麻杂岩分布范围的二分之一,主要岩石类型为云英闪长质—奥长花岗质—花岗闪长质片麻岩。本文对其岩石化学、地球化学特征进行了总结,并与冀东灰色片麻岩和西格陵兰努克片麻岩进行了对比。根据痕量元素特征对成岩构造环境、成岩物质来源和成岩方式进行了探讨。

| Abstract: | Gray gneisses accout for about one half distribution area of Archaean gneisses rocks in Fuping area. They mainly consist of tonalite-trondhjemite-granodiorite (TTG) gneisses. This paper summarized the petrochemistry geochemistry of the gneisses and compared them with the gray gneisses in E.Hebei, and the Nuk gneisses in W. Greenland. Based on the trace element concerntrition, authors also discussed the tectonic environment source materials and processes of the petrogeney. |
