摘要
福吉山铜矿成矿地质特点不同于山东已有的铜矿类型,属于构造热液成因类型。近SN向的平移断裂同时具有张扭性和压扭性双重力学性质,其中张扭性破碎带造就成矿空间,造成了矿体近等间距雁列式排列。受断裂构造的影响,矿区内节理、裂隙发育,为成矿热液的运移和积聚提供了良好的空间。区内沿裂隙充填形成的石英脉、褐铁矿脉、铜矿脉发育。
Geological characteristics of Fujishan copper mineralization is different from other existing copper deposits in Shandong province. It belongs to hydrothermal structure type deposit. The strike-slip fault with the trend of SN has the characteristics of both shear and pressure mechanical properties. Tensile shear fracture zones will creat mineralization space,and ore bodies will arrange in a nearly equidistant type. Affected by fault structures,joints and fissures developed well. It will provide good space for migration and accumulation of ore-forming hydrothermal fluid. Quartz veins,limonite veins and copper veins formed and filled along the fissures developed well.
