摘　　要：黑石山铜矿位于新疆哈密地区哈尔里克山东缘、大南湖古生代岛弧带东段,矿区内石英脉和花岗斑岩脉较为发育。基于大比例尺地质草测、物化探、高精度磁测及钻探工程等工作方法,对黑石山一带铜金多金属矿开展地质调查评价;总结了区内铜矿化的空间分布规律和主要控矿因素,掌握了矿区范围内的地层分布、地质构造特征、岩浆岩的数量和种类及分布情况,并初步圈定了铜矿蚀变带及矿化体的分布范围和数量;此外,结合黑石山一带区域地质背景,通过对已知矿床的调查,对比相邻成矿带铜矿的地质特征,对调查区铜矿找矿潜力进行了评价,为深部找矿及开发利用提供了依据。The Heishishan Copper mine is located in the east edge of Karlik Mountains and east section ofDananhu palaeozoic island arc in Hami Prefecture of Xinjiang. The quartz veins and granite porphyry vein are devel-oped well. Firstly, Some methods, such as large scale geological sketch survey, geophysical and geochemical data,high-precision magnetic measurement and drilling engineering have been applied to investigate and evaluate the Poly-metallic Cu-Au Deposits in Heishishan region. Secondly, the spatial distribution and main ore-controlling factors ofthe copper mineralization in this region have been summarized, and the stratigraphic distribution, the geologicalstructural feature, the amount, type and distribution of magmatie rocks have been grasped too. At the same time,the distribution range and quantity of copper alteration belt and mineralization body have been determined prelimina-rily. Additionally, we compare the geological characteristics of copper deposits with the adjacent metallogenic belt,then evaluate the prospecting potential in investigating copper deposit according to the geological background inHeishishan, investigation of known mineral deposit. The relative results can be regarded as a basis for deep oreprospecting and exploitation.
