山东福吉山铜矿构造控矿因素分析

摘要

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 min-eralization 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 flu-id.Quartz veins,limonite veins and copper veins formed and filled along the fissures developed well.%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。
