摘　　要：华南前寒武纪花岗岩分布相对较少,主要以新元古代为主,通过总结前人研究结果发现,华南不同地区新元古代花岗岩具有一定共性：过铝质-强过铝质特征,成岩年龄集中在800~830 Ma。大部分属于S型花岗岩,少部分属于I型花岗岩和I-S过渡型花岗岩;大部分为古老地壳的衍生产物,华南新元古代花岗岩有可能是碰撞、俯冲和地幔柱活动共同作用的结果。The Precambrian period granites are relatively few in South China, and they mainly belong to Neoproterozoic.From the previous studies, we can get the result that there are some commons in Neoproterozoic granite in south of China：they belong to eraluminous-strong peraluminous granites, and the age is about 800-830 Ma.Most of them are S-type granite,and few are I or I-S-type. They formed from the material of the old crust, and they may result from the collision, subduction and mantle plume activity.
