摘要
This paper reported the recent discovery of Hercynian granite at Nali of Qinzhou in Guangxi. The Nali granitic body has crystallization ages of 262 Ma obtained by LA-ICP-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 Ioft-com:office:smarttags" />ndochiese block. The Nali granites were generated at the late stage of this subduction, probably in a back-arc extension setting.
