摘    要:本文从钾质花岗岩的产出侵位特征、组构及矿物岩石化学特征等方面阐述了夹皮沟钾质花岗岩带的地质特征;通过对钾质花岗岩的成因、夹皮沟花岗岩-绿岩带地质简史、钾质花岗岩与花岗岩-绿岩带的关系、钾质花岗岩与金矿化的关系4方面的阐述,得出结论:钾质花岗岩与金矿为"伴生"关系,金矿的形成在时间上、空间上均与钾质花岗岩相伴。在此基础上,指出了金的找矿方向:夹皮沟区金矿的寻找不应远离钾质花岗岩,应加强在钾质花岗岩的内接触带或岩体内的找矿。

关 键 词:夹皮沟  钾质花岗岩  地质特征  金矿  找矿方向

Abstract:In this paper, from occur emplacement features, fabric and mineral rock chemical characteristics of potassic granite, the authors expound the geological features of potassium granitic belt in Jiapigou. By the statement in four aspects, such as the causes of potassic granite, geologic brief history of granite-greenstone belt in Jiapigou, the relation of potassic granite and granite-greenstone belt, and the relation of potassic granite and gold mineralization, we draw the conclusion:potassic granite and gold ore are“associated”relationship, in the time and space, gold deposit forming are associated with potassic granite. On this basis, the authors points out the gold prospecting direction:in Jiapigou area, seeking gold ore should not far from potassic granite, should strengthened in the endocontact or rock mass of potassic granite.
Keywords:Jiapigou  potassic granite  geological features  gold ore  prospecting direction
