摘　　要：结合勘查实践,系统分析滇中地区已有的地质资料及近年来的成矿理论基础上,对滇中地区的铜矿成矿规律进行总结。本区铜矿类型主要为火山喷发—沉积变质型铜矿(大红山式铜矿)、层控型铜矿(东川式铜矿)、沉积型铜矿(砂岩型铜矿)、其次为中-低温热液型铜矿、玄武岩型铜矿。同时根据综合研究,分析已知矿床的成矿环境及控矿因素,概括出本区铜矿找矿标志,提出两个有利的找矿区域,为本区的铜矿床的勘探工作提供依据和方向。On the base of analyzing the geological data and metallogenic theory of copper deposit in central yunnan,the mineraliztion laws of copper deposit is analyzed.It is concluded that the main types of the copper deposits are volcaniceruption-sedimentary copper （DaHongshan type copper）,stratabound copper （Dongchuan type copper）, sedimentation copper （sandstone type copper）;the followed types are mid-low temperature hydrothermal type copper,basalt type copper.At the sametime, According to comprehensive research, prospecting signs for copper deposit are pointed out by analyzing and comparing metallogenic enironmentn and ore controlling factorsn of above lead copper deposits .Therefore,two prospective areas are divided ,which provide foundation and direction for further prospecting and exploration of copper deposit in the deposit accumulation region.
