基　　金：中国大陆周边地区主要成矿带成矿规律对比及潜力评价计划项目--中哈合作巴尔喀什-准噶尔斑岩铜矿成矿条件对比研究(1212010661315);中亚五国矿产资源勘查开发指南(1212010811066);国家科技部"十一五"科技支撑项目--兴都库什-西昆仑成矿带岩浆成矿作用对比研究(2006BAB01A03-2-2)共同资助

摘　　要：研究区共划分出4个斑岩-矽卡岩成矿省(区),21个成矿带,49个矿带.对各成矿带、矿带中的代表性矿床作了描述.从成矿时代看,多数矿床形成于石炭—二叠纪,少数形成于早古生代,成矿构造环境多数位于有隐伏刚性基底之上,形成于造山旋回构造岩浆活化带.从成矿类型看,斑岩体多形成斑岩铜(钼)矿,但由于围岩的性质差异,有时可形成矽卡岩型(卡拉塔斯Ⅰ,Ⅱ)或块状硫化物型.此外,由于斑岩体酸性程度不同和区域地球化学性质的差异,除铜矿外,少数矿床以钼为主(阿克库都克矿床),个别的以金为主(吉尔吉斯斯坦塔尔迪布拉克).In the study area,divided porpyry and skarn deposit to 4 minerogenetic province,21 minerogenetic zone,49 ore belt,Also described typical ore deposit of every ore belt, From on minerogenetic epoch,major take formed perrnocarboniferous period,very few has early palaeozoic;On the minerogenetic tectonic enviroment ,maj or located on the rigidity basement of lie concealed, formed Igneous Instrusion and Volcanism of orogenic cycle, On the minerogenetic category because of nature diffirence of country rock,though major ore deposit is porpyry ,but some formed skarns （Qaratas Ⅰ,Ⅱ）,some formed massive sulfide type ;in addition ,Because of acidic degree and difference of regional geochemistry, except for copper ore deposit ,some give priority to gold （ kyrgyzstan Taldybulak）,Small number ore deposit give priority to molybdenum （Aqkuduk ore deposit）.
