相山矿田铀矿地质研究进展与趋势

相山铀矿是华南最大的产于火山-侵入杂岩体中的热液脉型铀矿田。文章对相山铀矿地质研究的历史进行了简略回顾,重点阐述了铀矿地质研究的新进展,主要有:火山杂岩时代为早白垩世、火山岩浆具有反方向演化特点,成矿作用是一个相对连续的演化过程,铀矿类型归属斑岩型,属于与燕山晚期火山-斑岩作用有关的铀或铀-多金属矿床成矿系列。最后,文章展望了未来的研究方向。

Progress and trend in the research on uranium geology in Xiangshan ore field

Xiangshan ore field occurred in volcanic-intrusive complex body is the largest hydrothermal vein type uranium deposit in south China.This paper briefly reviews the history of geological research on Xiangshan uranium ore field’ and mainly focuses on the new progress in the research on the uranium geology as follows: the age of volcanic complex is confirmed as early Cretaceous,the magma of volcanic rocks is characterized by a reversal evolution,the mineralization shows a relatively continuous evolution process,the uranium deposit belongs to a porphyry type that can be classified into the uranium or uranium-polymetallogenic series related with the late Yanshanian volcano-porphyry.Finally,the future research trend is predicted.
