我国东南部中生代产铀花岗岩体铀成矿时代规律

URANIUM METALLOGENETIC EPOCH OFMESOZOIC URANIUM-BEARING GRANITICINTRUSIONS IN SOUTHEASTERN CHINA

作者对诸广山、桃山、贵东、佛岗等花岗岩体在野外，室内进行了研究，提出产铀花岗岩体铀成矿时代的认识。铀成矿主要在燕山早期，少量产于印支晚期。

Besed on the field reconnaissance and office analysis of Guanshan, Taoshan,Guidong, Fogang and other granitic intrusions,the author proposes the testinony on uranium metallogenetic epoch uranium -bearing granitic intrusions. Uranium mineralizationoccured mialy during the early Yanshan epoch,and occasionaly during the late Indochineseepoch.
