摘要
在皖南地区东至到泾县一带,已发现若干微细浸染型金矿,其含矿层位为震旦系至下古生界,矿体受高角度断裂带和层间破碎带控制。本文通过矿床地质特征和成矿条件分析,探讨了可能存在的矿源层及分布状况,提出江南古断裂对金矿的控制作用,并认为本类型金矿成因类型属于地下热卤水浸滤为主的浅成低温热液矿床。
The gold deposits of impregnated type have been found from Dengzhi to Jin county.Their ore-bearing strata is from Sinian System to lower palaeozoic erathem.The ore bodies are centrelled by interfermational and compression faults.Based on analysis of Geological features of orebedies and met- allegenetic conditions,this paper has discussed possible ore-source beds in the belt and their distribu- tion,and presents controls of Jiangnan pales-fault for gold deposits,it is considered that this type of gold genesis belongs to epitheymal deposit type which is dominantly hydrothermal brine.
