中文摘要：

本文综述了中国东南部晚中生代A型花岗岩类的分布和成因的研究进展。按其形成时代和空间分布,将该区的A型花岗岩类分为4个带,即赣南-闽西南带、湘桂粤带、赣杭带和沿海带,并进行了年代学、地球化学和岩石组合的对比分析。在此基础上,讨论了4个分带的形成与古太平洋板块向中国东南大陆俯冲和后撤的过程。

英文摘要：

This study has reviewed the distribution and petrogenesis of late Mesozoic A-type granitoids in SE China.These A-type granitoids belong to four belts（S Jiangxi-SW Fujian belt,Xiang-Gui-Yue belt,Gan-Hang belt and coastal belt）due to their temporal-spatial distribution.Based on the comparative analysis of chronology,geochemistry and magmatic associa-tion,this study has discussed the formation of A-type granitoids and the subduction and slab rollback process of paleo-Pa-cific plate beneath SE China.
