摘　　要：矿体受地层和构造双重控制,褐铁矿化、硅化构造角砾岩型金矿石,微细浸染状结构。低温汽水热液与浊积岩层中的钙质交代,运移至北西西向断层次级破碎带中富集成矿。The ore body is controlled dually by strata and structure.The Au ore of brown-yellow ferritized silicified structural breccia type is with micro-dissemination texture.The low T gas-aqueous thermal fluid and the Ca metasomatism in turbidite migrate into the secondary fracture zone of NWW fault,concentrate and form the ore deposit.
