| 摘 要： | 本文研究了金厂峪金矿太古代斜长角闪岩中构造岩的特征和分布特点;根据片岩带内存在纯片岩地段、片岩带内有岩墙和两种含金脉体地段所呈现的无对称分带性、岩墙和脉体的接触关系,论述了断裂构造性质、控矿作用、热液充填期次、成矿时代;指出产于斜长角闪岩中的金矿床,并非都形成于太古代,在冀东燕山准地槽内应注意燕山期成矿作用。

| Abstract: | The characteristics and distributing features of the amphibolites from Archaean era are discussed in this paper. On the basis of that pure schists occurred in the schists belt,the no- symmetric distributation of dyke and two kinds of bearing-gold vein and the contact relationship between dyke and vein, the following problems are discussed-properties of the fracture structure, ore-controling function, the times of hydrothermal filling and ore-forming time, It is also pointed out that all gold deposits occurred in the amphibolites were not formed during the arcbaean era and that the ore-formingfunction during yanshan period should be noticed in the Yanshan meta-geosyncline in easten Hebei province. |
