冀西北水晶屯金矿地质特征及成矿作用研究

Study on Geological Characteristics and Mineralization of Shuijingtun Gold Deposit in Northwestern Hebei Province

摘要:

水晶屯金矿位于我国重要的金矿集中区——河北省张宣(张家口—宣化)幔枝构造区南部，是张宣地区比较有代表性的中型金矿,张宣幔枝构造演化过程中形成的一系列多期次、多阶段的褶皱和断裂构造体系对该矿的形成和演化起着重要的控制作用。该文以幔枝构造理论为指导，在总结前人资料基础上,通过野外调查，室内综合分析，认为其外围及深部仍具有较大找矿潜力。

Abstract:

Shuijingtun gold mine locates in south of Zhangxuan (Zhangjiakou-Xuanhua) mantle branch areas which is the important gold concentration area in Hebei province. It is a representative medium-sized gold mine. A series of multi-period and multi-stage fold and fault tectonic systems formed in the evolution period of Zhangjiakou-Xuanhua mantle branch. It plays an important controlling role in the formation and evolution of the mine. By using mantle branch theory as a guide, through field survey and indoor comprehensive analysis on the basis of previous datas, it is regarded that there still have a great prospecting potentiality in its peripheral and deep part of Shuijingtun gold mine.
