| 摘 要： | 安徽省东至地区位于扬子陆块北缘,跨下扬子前陆带和江南隆起带两个次级构造单元,独特的大地构造环境造就了本区有利的金矿成矿地质条件,形成多种类型的金矿床,其成因类型主要包括岩浆热液型和风化壳型,工业类型主要有破碎带蚀变岩型、含金石英脉型、微细粒浸染型及红土型。各类型金矿分类聚集,形成两个主要的金矿成矿带。沿赵家岭断层带以破碎带蚀变岩型为主,伴有含金石英脉型,中畈—戴家一带,赵家岭—杨家山一带均具较大找矿潜力,是本区金矿勘查重点地区,九华庄等地也具一定的找矿潜力;沿高坦断裂以微细粒浸染型为主,伴有破碎带蚀变岩型及红土型,查册桥地区是其重点勘查区,铜锣尖、小河等地找矿潜力也较大。

| Abstract: | The Dongzhi area, Anhui Province is situated on the northern fringe of the Yangtze landmass, overlying two secondary tectonic units of the Lower Yangtze Foreland Belt and the Jiangnan Uplift Belt. The unique tectonic＇setting creates favorable gold mineralization geological conditions and forms diversified gold deposits, mainly classified into magmatic hydrothermal type and weathering crust type by origin, and into fracture zone altered rock type, auriferous quartz vein type, micro- to fine-grained disseminated type and laterite type by industrial definition. Each type of gold has a separate cluster thus forming two major gold mineralization belts. The Zhaojialing Fault Zone is dominated by fracture zone altered rock type of gold, associated with auriferous quartz vein, with great potential along the Zhongfan- Daijia, and Zhaojialing-Yangjiashan as the major target, and some potential in Jiuhuazhuang,etc;the Gaodan Fault is mi- cro- to fine-grained disseminated gold-dominant, accompanied with fracture zone altered rock type and laterite type, with the Zhaceqiao area being the priority target, and also having some potential in Tongluojian,Xiaohe, etc. |
