摘要
松树沟铜矿大地构造主要处于伊犁-伊赛克湖微板块的分布范围内的东缘位置,该区同时对阿吾拉勒晚古生代裂谷系,以及博罗科努古生代复合岛弧带进行横跨。前者东部方向尖灭区域即研究区,褶皱与断裂是该区内的主要构造特征,并且区内具有非常强烈的岩浆活动,广泛分布侵入岩与火山岩。由于上述构造特征的存在为该区成矿提供了非常有利的条件。随着区域性地球物理、地球化学等基础调查工作和成矿规律的不断深入研究,在西天山地区找矿工作有了重大突破,本文以西天山松树沟铜矿为例:该矿床属富铜、富铁多金属成矿带,喀什河断裂以南的巩乃斯裂谷区内,经调查研究认为该铜矿属斑岩型铜矿床,矿床的形成处于研究区内火山的强烈活动、岩浆侵位活动最活跃时期,属西天山地区的高背景区或异常区,成矿地质条件相当优越。
Pine ditch copper tectonic mainly in ili - isay lake of microplate east edge location, within the scope of the distribution of the area at the same time, we pull le late Paleozoic rift system, as well as bo rocco＇s Paleozoic across the island arc belt. Pinchout area in the study area, namely the former east direction to fold and fracture is the main tectonic characteristics in the district, and has the very strong magmatic activity in this area, wide distribution of intrusive rocks and volcanic rocks. As a result of the existence of the tectonic characteristics of the ore-forming provides a very favorable conditions. As the basis of regional geophysical and geochemical survey work and metallogenic regularities, the deepening of the research in the prospecting work had a major breakthrough in the west tianshan region, west tianshan pine gap copper mine as an example in this paper, the ore deposit belongs to the rich copper, iron rich polymetaUic metallogenic belt, south of kashi river fault rift zone, the research that the mine belongs to the porphyry copper deposit, the formation of ore deposits in the research area of the volcano strong activity, magmatic emplacement, the most active period belongs to the high background area or abnormal area of the west tianshan region, a superior metallogenic geological conditions.
