摘要
东沟金多金属矿床位于西秦岭凤太矿集区东部,矿体赋存于泥盆系地层中,金矿(化)体的产出严格受星红铺组千枚岩地层的控制,NW向构造发育程度控制着金矿化的强度。矿区已发现多条矿带,容矿岩石主要为铁白云质粉砂质千枚岩,矿石类型主要为石英脉型,属构造蚀变岩型金矿床。综合矿区地层、构造、蚀变特征、控矿因素等认识,认为东沟金矿成矿地质条件有利,有形成中型金矿床的可能。
Donggou gold and polymetallic deposit is located in the east of Feng-Tai ore-concentrated areas of west qinling. The orebodies occur in devonian system formation.The Gold deposit （mineralization） body is strictly controlled by phyllite stratum in Xinghongpu Group. The degree of gold mineralization is controlled by NW-trending tectonic development. Many ore belt have been found in this ore district.The hosth rocks are mainly iron dolomitic silty phyllite, and the ores are mainly of quartz vein type, belongs to tectonic altered rock type gold deposit. Comprehensive mining strata, tectonic, alteration characteristics, ore-controlling factors, we think donggou gold metallogenic geological conditions are favorable, and has the potential to form a medium sized gold deposits.
