| 摘 要： | 对中条山以及狼山北坡层状铜矿的研究以及国内外其它类似层状铜矿的对比，认为幔源基性岩浆活动与层状铜矿存在密切的时空联系，可作为成矿所必需的热源、热液源和矿源岩．其控矿成矿方式可能有展状矽卡岩化、驱动海底与沉积岩系内部热卤水对流循环，在有利界面处成矿以及韧性剪切活化成矿等．

| Abstract: | The mantle-derived, strata-parallel mafic sheets developed in typical Zhongtiao and Lansha stratiform copper and multi-metal deposits, are found to have a very close relationship to metallogenesis temporally and spatially.With the comparison and reference of some other well-known stratiform copper deposits such as Dongchun, White Pine and Mt.Isa, it is suggested that the mantle-derived mafic sheets are of important source rock for heat, hydrothermal fluid, metals and sulfurs needed for stratiform mineralization. And the possible processes of mineralizations are advanced and discussed, such as stratiform skarnization, interfacial metallogenesis by driving mechanism of seafloor and Particularly subseafloor hydrothermal brine convective circulation and the ductile shearing and mobilization. |
