大宝山大型多金属矿区,曾进行大量的地质、物化探工作,积累了不少资料.该矿床地球化学异常的分布有明显规律.地质概述矿区位于北江新华夏断裂带东侧,大东山-贵东东西构造带与北江断裂带的交合处.区内广泛出露古生代地层,尤以泥盆系、石炭系分布最广;主要为一套陆源碎屑及浅海碳酸盐建造.区内火成活动广泛发育,形成贵东花岗岩体,出露于区域之北,呈东西方向分布.次英安斑岩体分布于区域东部,呈断结弧形分布.此外尚有次英安斑
Dabaoshan large polymetallic mining area, has conducted a large number of geology, geophysical and geochemical exploration work, accumulated a lot of information.The distribution of geochemical anomalies have obvious rules.Geological overviewThe mining area is located in theBeijiang RiverNew Huaxia fault east, Dadongshan - expensive East-West structural belt and the Beijiang fault zone intersection.The Paleozoic strata are widely exposed in the area, especially the Devonian, Carboniferous is the most widely distributed; mainly composed of a set of terrestrial debris and shallow marine carbonate. Extensive development of activities, the formation of Guidong granite body, exposed in the north of the region, showing the east-west direction distribution.The sub-Yingan porphyry body distributed in the eastern part of the region, showing a broken arc distribution in addition there are times the British spot
