摘　　要：塔吉克斯坦位于中亚腹地,大地构造位置上处于古亚洲与特提斯两大构造域的结合部位,特殊的大地构造位置使其具有丰富的矿产资源。笔者以地球化学块体理论为指导,借助低密度地球化学数据与区域地球化学信息分析系统,从地球化学块体角度对塔吉克斯坦金矿资源潜力进行预测。塔吉克斯坦全境共圈定金地球化学块体8处,结合已知金矿床及成矿地质背景对各金地球化学块体特征进行总结,在综合研究的基础上,认为塔吉克斯坦金资源潜力巨大,按照金资源量由大到小的顺序依次为泽拉夫尚东金地球化学块体、卡拉马扎尔西金地球化学块体、泽拉夫尚西金地球化学块体、中帕米尔金地球化学块体、卡拉库里北金地球化学块体、东南帕米尔金地球化学块体、卡拉马扎尔东金地球化学块体和穆克苏金地球化学块体,塔吉克斯坦南天山地区有发现超大型金矿的潜力。Tajikistan is located in the hinterland of Central Asia,the combination of Paleo-Asian tectonic and Tethys domains.Its special tectonic location makes it rich in mineral resources.Using low-density geochemical data and regional geochemical information system,this paper predicts the potential of gold resources in Tajikistan based on the theory of geochemical blocks.The characteristics of 8 gold geochemical blocks in Tajikistan were marked out based on the known gold deposits and metallogenic geological background.Through comprehensive study,it is concluded that Tajikistan has great potential of gold resources.The quantity of gold resource from large to small is as follows:Zerafshan,west Qatkal,Pejikent,central Pamir,north Karkul,south-east Pamir,east Qatkal and Mukcu.The southern Tianshan in Tajikistan has a potential to find a super-large deposit of gold.
