Middle Jurassic Folds in Northern Lianhuashan Fault Zone in Guangdong Province and Its Tectonic Significance

摘要: 为限定华南东部沿海中生代褶皱的形成时代,研究其形成机制,以广东莲花山断裂带北段晚三叠世至中侏罗世地层褶皱为研究对象,进行了构造解析和相关地质体的年代学分析.地层产出的蕨类、篦羽叶和双壳类等化石,证实其晚三叠世至中侏罗世的沉积时代.NE向褶皱被晚侏罗世火山岩(锆石U-Pb年龄163~148 Ma)不整合覆盖,NW向褶皱被晚侏罗世花岗岩(锆石U-Pb年龄157~154 Ma)侵入,综合前人在地层中获取的碎屑锆石最新U-Pb年龄(171~173 Ma),分析显示褶皱于中侏罗世中晚期近同期形成.NE向褶皱为纵弯褶皱,形成于NW-SE向区域性挤压作用;NW向褶皱为剪切褶皱,受控于褶皱逆冲带中NW向横断层作用.广东莲花山断裂北段中侏罗世不同走向褶皱均是华南板块对古太平洋板块俯冲的响应.Abstract: In order to limit the timing of Mesozoic folds in the eastern coast of South China and study the formation mechanism, in this paper it studies the folds of the Late Triassic to Middle Jurassic strata in the northern section and analyzes the geochronology of related geological bodies. Fossils of ferns, pinnules, bivalves found in the strata confirm the sedimentary age from the Late Triassic to the Middle Jurassic. The NE fold is invaded by the Late Jurassic volcanic rock (zircon U-Pb age at 163-148 Ma). The NW fold is invaded by the Late Jurassic granite (zircon U-Pb age at 157-154 Ma). Combined with the previous debris zircon U-Pb age obtained in the formation (171-173 Ma), comprehensive analysis indicates that the fold was formed in the middle and late Middle Jurassic. NE fold is longitudinal bending fold, which is the product of regional NW-SE extrusion; NW fold is formed by shear fold, which is the product of NW transverse fault in the fold reverse zone. The different trending Jurassic folds in the northern section of Lianhuashan fault, Guangdong, are the tectonic response of South China block to the subduction of the Paleo-Pacific plate.
