广西钦州地区那丽花岗岩LA-ICP-MS锆石U-Pb定年及其地质意义
LA-ICP-MS zircon U-Pb age of the Nali granite in Qinzhou area of southern Guangxi and its geological significance.
摘要
Abstract
This paper reported the recent discovery of Hercynian granite at Nali of Qinzhou in Guangxi. The Nali granitic body has crystallization ages of 262Ma obtained by LA-1CP-MS zircon U-Pb method. In Permian period, the collision between Qiangtang-Sibumasu block and Indochina block resulted in the thrusting of South China block beneath Indochina block. The Nali granites were generated at the late stage of this subduction, probably in a back-arc extension setting.关键词
