| 摘 要： | 论述了马脑壳金矿区成矿地质构造背景和构造变形特征，探讨了构造演化及应力场特征。重点总结了构造控矿规律：即不同级序断裂对金矿的控制、NWW向韧脆性扭压性断裂及NIVE－NE向张扭性断裂对金矿的控制、断裂性质转化及复合叠加对金矿的控制、控制金矿化局部富集的构造因素、控矿断裂构造地球化学特征及与成矿的关系。指出本区金矿的形成经历了成矿物质多期活化—迁移—富集的复杂演化过程。

| Abstract: | The present paper deals with geological setting and tectonic deformation of Manaoke gold ore deposit and makes an approach to its tectonic cvolution and stress field features.Structural ore controls such as ore control of different ordered faults, ore control of NWW-trending ductile-brittle shearing compressive fracture and NNE-trending tenso-shear fracture and ore control of composite and superimposed rupture are summarized. Structural ore control of localization of gold mineralization and relation of tectonic geochemistry to gold mineralization are discussed. Gold mineralization underwent multiphase remobilization and enrichment. |
