摘　　要：杨树沟地区金矿床处于东昆仑成矿省伯喀里克—香日德印支期金、铅、锌、铁、石墨(铜、稀有、稀土)成矿带的东段,属典型的断裂构造控制的热液蚀变岩型金矿床。近些年来杨树沟矿区投入的勘查手段有限,工作程度较低,对该矿床的综合研究工作相对较少,为了加强矿区金矿成矿规律的研究,更进一步寻找新的金矿体,本文从地质背景、化探特征、矿床特征及矿石特征等方面进行了较深入分析,初步总结了断裂构造与成矿的关系、矿床特征及成矿规律等,浅析了杨树沟地区金矿床找矿前景,研究成果可为后期寻找新的金矿体提供参考。The Yangshugou gold deposit is located in the eastern part of the Bokalik-Xiangride Indochinese gold metallogenic belt of the East Kunlun metallogenic Province.It is a typical hydrothermal altered rock type gold deposit controlled by fault structure.In recent years,the exploration means of Yangshugou mining area are limited,the work degree is low,and the comprehensive research work of this deposit is relatively few.In order to strengthen the research of gold mineralization law in the mining area and further search for new gold ore bodies,this paper has carried out in-depth analysis from the geological background,geochemical exploration characteristics,deposit characteristics and ore characteristics,etc.This paper summarizes the relationship between fault structure and mineralization,deposit characteristics and metallogenic law,and analyzes the prospect-ing prospect of gold deposit in Yangshugou area.The research results can provide reference for the later search for new gold ore bodies.
