大宝山是一个大型多金属矿区,位于粤北山字型前弧东翼内侧,北江新华夏断裂带的东侧,大东-贵东-九连山东西构造带与北江新华夏系构造带复合处.区内出露地层主要为泥盆纪及石炭纪的一套滨海—浅海相砂页岩-碳酸盐建造,次为寒武纪浅变质砂板岩建造.局部尚有早侏罗世陆盆成煤建造.区内断裂发育.火成活动主要有燕山Ⅳ期次英安斑岩和Ⅴ期花岗闪长(斑)岩.船肚-大宝山花岗闪长(斑)岩体,受东西构造控制,东西长3200米,南北宽300～600米,最宽处达800米,呈岩株状产出.岩体受几组断裂破坏错移600米,成为船肚岩体与大宝山岩体的分界线.船肚岩体被剥蚀,
Dabao Mountain is a large polymetallic mining area located inside the eastern wing of the Yuedi mountain type forearc arc. To the east of the North China Xinhuaxia fault zone, the complex of the Dadong-Guidong-Jiulianshan structural belt and the Beijiang-Xinhuaxia structural belt The exposed strata in the area are mainly composed of a set of coastal-shallow marine sand shale-carbonate of the Devonian and Carboniferous, followed by the Cambrian super-metamorphic sand slate, and there are also parts of early Jurassic continental basin Coal formation.The faults are developed in the area.The main volcanic activities include the Yanshan Ⅳ period Yingan porphyry and the Ⅴ period granite diorite (plagioclase) rock.The belly-Dabaoshan granodiorite (plaque) Structural control, east-west length of 3200 meters, north-south width of 300 to 600 meters, 800 meters wide at the widest point, was rock-like output of rock mass by several sets of fault dislocation of 600 meters, becoming the Chou Fu body and the Dabaoshan rock Body of the dividing line. Chuen body rock was eroded,
