湖南省大官冲矿区付家冲矿段金矿地质特征与矿床成因研究

Study on the geological characteristics and genesis of the gold deposit in Shanxi Province

大官冲矿区地处扬子地台之江南台背斜东南缘,位于湘东北金矿成矿区、平江—浏阳深大断裂旁、板杉铺岩体北侧。矿区岩浆岩活动频繁,主要有浅成侵入的细粒花岗岩脉和花岗闪长岩脉等,在构造破碎带及其两侧,岩石受热液作用蚀变普遍加强。矿区地层、构造、岩浆岩及围岩蚀变对矿床形成具有很重要的控制作用,本文对矿区地质特征与矿床成因进行深入研究,研究成果对以后的地质勘查具有很重要的指导意义。

Big officer rushed mining area is located in jiangnan anteclise southeast margin of Yangtze platform,located in the northeast of hunan gold metallogenic deep fault that,at pingkiang and liuyang shop,Chinese fir,rock mass near the north side.There are a lot of rock slurry activities in the mining area,which mainly include fine grained granule and granite vein,which are shallow and intrusive.In the structural fracture zone and on both sides of the rock,there is a general strengthening of the effect of the thermal fluid on the rocks.Mining area formation,structure,magmatic rock and wall rock alterations of ore deposit formation have very important control action,this paper conduct the thorough research to the mine geological characteristics and genesis,research on the later geological exploration has important guiding significance.
