摘要
皖南东至—陉县一带分布的若干微细浸染型金矿,其含矿层位为震旦系与下古生界。矿体受层间破碎带和挤压性构造断裂控制。通过本区地层含金性研究和控制因素分析,探讨了本区内可能存在的矿源层及分布状况,并提出了江南古断裂对金矿的控制作用和不同类型构选的控金作用。
The impregnated gold ore deposits in the area of Dongzhi to Jingxian,southern Anhui Province occur in the Sinian System and Lower Palaeozoic Erathem.The ore bodies are controlled by interformational fracture zone and compressive structure.By means of study on Au-containing features of the sequence and ore-forming factors,the potential source beds of gold ore and their distribution have been studied in the paper.In addition,the dominating effect of ancient Jiangnan Fault Zone and structures of different kinds on the gold ore deposits have been also mentioned in the paper.
