新疆黑石山地区铜金多金属矿床成矿地质特征及找矿前景分析

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。

Geological Characteristics and Prospecting Potential of the Polymetallic Copper-Gold Deposits in Heishishan region ,XinJiang

The Heishishan Copper ore is located in the east edge of Karlik Mountains and east section of Dananhu palaeozoic island arc in Hami Prefecture of Xinjiang,The quartz veins and granite porphyryvein are developed well. Firstly, Some methods, such as large scale geological sketch survey,geophysicalandSgeochemical data, High-precisionSmagneticSmeasurement and drilling engineering have been applied to investigate and evaluate the Polymetallic Copper-Gold Deposits in Heishishan. Secondly, the spatial distribution and main ore-controlling factors of the copper mineralization in this region have been summarized, and the stratigraphic distribution, the geological structural feature, the amount, type and distribution of magmatic rocks have been grasped too. At the same time, the distribution range and quantity of copper alteration belt and mineralization body have been determined preliminarily. 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 in Heishishan, investigation of known mineral deposit. The relative results can be regarded as a basis for deep ore prospecting and exploitation.
