    Deformation time limit of ore-controlling structures in Lianhuashan fault zone along the South China coast:Constraints from zircon U-Pb age and stratigraphic age

      摘要
    • 摘要: 莲花山断裂带是中国东南沿海广东省境内一条重要的NE向断裂构造带，同时也是一条重要的锡、钨、铜、铅锌多金属成矿带。本文通过莲花山断裂带和典型矿区野外地质观测及断裂带内发生剪切变形作用的花岗岩体锆石U-Pb年龄测定，初步探讨了莲花山断裂带内韧性变形时限、脆性边界断裂发育时限，以及韧性剪切变形与成矿的关系。研究表明莲花山断裂带内韧性变形时限在129~127 Ma，脆性的边界断裂发育于官草湖组和合水组地层沉积时限之间，莲花山断裂带中韧性剪切变形早于成矿发生时间，韧性剪切变形为成矿提供了容矿空间。

       

      Abstract: The Lianhuashan fault zone is not only an important NE-striking fault zone in Guangdong Province but also a significant tin, tungsten, copper, lead-zinc polymetallic metallogenic belt. Based on geological field observation of the Lianhuashan fault zone and the typical mining area as well as the measurement of the zircon U-Pb age of the granite intrusive with ductile deformation, the authors preliminarily investigated the time of ductile deformation and boundary fault and the relationship between deformation and mineralization in this paper. The result indicates that the ductile deformation time in the Lianhuashan fault zone is around 129-127 Ma, and the brittle boundary fault was developed between the sedimentary time of Guancaohu Formation and the Heshui Formation. The age of ductile shear deformation in the Lianhuashan fault zone was earlier than the mineralization time, and the ductile shear deformation provided the ore-bearing space for mineralization.
