华南铀矿分布广泛，铀矿类型包括花岗岩型、斑岩型、火山岩型、碳硅泥岩型和砂岩型，铀矿化通常认为是分期分阶段形成的。本文通过华南130个矿床(点)共361个年龄数据的统计分析，发现铀成矿作用主要发生在145.5Ma以后的中新生代，特别是白亚纪和古近纪。成矿时代具有区域上的同时性，铀成矿作用是一个相对连续的过程。

Uranium deposits,which include granite-type,porphyry-type,volcanic rock-type,carbon silicon mudstone-type and sandstone-type,are widely distributed in South China.It is generally recognized that uranium mineralization is forms by stages and phases.The statistical analysis of total 361 age data from 130 U deposits (spots)in South China area shows that the uranium mineralization mainly occurs in the Meso-cenozoic Era after 145.5Ma,particularly in Cretaceous and Paleogene.The metallogenic epoch of the same region is of synchrony,and the uranium mineralization is a relatively continuous process.
