    Ore-controlling and metallogenic role of interlayer-slide fault in the carbonate formation, southern China

    • 摘要: 碳酸盐岩系层滑断裂在中国南方古生代地层中广泛分布,是一种重要的控矿和成矿构造。厘定碳酸盐岩系层滑断裂的基本类型、形成机理和控矿作用对相关矿床的找矿具有重要意义。基于层滑断裂所属含矿岩系的岩性组合、构造样式及其与主干断裂的相互关系,初步将层滑断裂划分为4种基本类型,即碳酸盐岩与泥页岩界面+层滑断裂复合型,平行不整合面+层滑断裂复合型,逆冲推覆构造台阶式断层断坡+断坪复合型和陡倾斜主干断层+旁侧缓倾斜层滑断裂复合型,分别总结了不同类型层滑断裂的控矿特征,并列举其典型的矿床实例,讨论了层滑断裂的控矿作用和成矿作用,将层滑断裂的形成过程归纳为层间滑动、层滑断层、叠加断层3个阶段。

       

      Abstract: The interlayer-slide faults in the carbonate series are widely distributed in the Paleozoic strata in southern China. These faults constitute an important ore-controlling and forming structure. Determining the basic types, formation mechanism, and ore-controlling effects of the interlayer-slide faults is of great significance in the search for related deposits. Based on the lithological combination of the ore-bearing rock series, structural style and the relationship with the main fault, the authors divided the interlayer-slide faults into four basic types:the compound type of carbonate and shale boundary with interlayer-slide fault, the disconformities boundary with interlayer-slide fault, the thrusting nappe structure with stepped ramp and flat, and steeper slope master fault with gently inclined secondary interlayer-slide faults. The ore-controlling characteristics of different types of interlayer faults and typical examples were introduced and the roles of interlayer faults in ore-controlling and metallogenic process was discussed. Three stages of the formation of the interlayer-slide fault were summarized, which are slide fault in interlayer, interlayer-slide fault and superimposed fault.
