摘要:
江家冲金矿处于衡东—浏阳新华夏系隆起带中段的湘东金铅锌多金属成矿带内，成矿条件较好。该矿区内金矿化主要产于中元古界冷家溪群小木坪组中，受区域北东向断裂及次级北西向断裂控制。1∶1万土壤地球化学测量结果表明：Au元素离散程度与叠加系数均较高，表明其具有一定的成矿潜力；划分出Au异常带3处，圈出综合异常带4处。初步总结了控矿因素，并进行了找矿方向分析，认为矿区已发现矿（化）脉中深部及综合异常浓集中心具有较好的找矿潜力，为进一步找矿指明了方向。

Abstract:
Jiangjiachong Gold District is located in the eastern Hunan gold-lead-zinc polymetallic metallogenic zone,which sits in the middle part of the Hengdong-Liuyang new Cathaysian uplift belt.The gold metallogenic conditions are good here.In the district,the gold mineralization mainly occurs in the Xiaomuping Formation,LengJiaxi Group of the Middle Proterozoic,controlled by northeast regional faults and northwest secondary faults.According to 1:10 000 soil geochemistry survey,the elemental dispersion degree and superposition coefficient of Au are both relatively high,indicating certain prospecting potentials;3 A-controlling factors and analysis of prospecting direction,it takes that there are great prospecting potentials in the district at the middle-deep part of known ore(mineralized) veins and the concentration center of comprehensive anomaly,pointing the direction of further prospecting.
