山东福吉山铜矿构造控矿因素分析

Analysis on Structural Ore-control Factors of Fujishan Copper Deposit in Shandong Province

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。

Abstract:

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.
