| 摘 要： | 广东西淋岗岩体出露的地质剖面为研究花岗岩成因提供了大量信息.对该岩体的野外地质调查发现:下白垩统白鹤洞组红层(K1bh)与下伏花岗岩体呈突变接触关系,接触界面之下的花岗岩中含大量红岩碎屑,且红岩碎屑往下逐渐减少.岩石地球化学及矿物学测试结果表明:西淋岗花岗岩的成岩物质,应来自盖层之下包括下白垩统白鹤洞组下部红层在内的岩...

| Abstract: | Lots of information concerning granite genesis can be obtained from the geological sections of Xilingang granite body in Guangdong Province.The sections indicate that the Baihedong Formation(K1bh) formed in the Early Cretaceous acted as a residual cap over the Xilingang granite body with abrupt contact in between.The granite underlying the contact contains numerous red bed clastics that reduce gradually with increasing depth in the rock body.The results of geochemical and mineralogical analysis suggested th... |
