江西省铀成矿地质环境及新一轮找矿方向

Uranium Metallogenic Geological Environment and Prospecting Prospects in Jiangxi Province

江西省铀成矿地质环境的研究习惯于按不同铀矿类型而相互割裂。文章在阐述江西省铀矿床时空分布特征的基础上,对铀成矿基本物质来源从大时空尺度和历史演化角度进行了研究,并进而分析了铀成矿地质环境。笔者认为,江西省铀矿床具特定时空分布,铀成矿与岩浆作用具成因联系,岩浆作用实现了区域成矿物质从"源"到"汇"物质转移的动力学过程,在中生代构造—岩浆—地球动力学背景之下发育的岩浆热液系统的演化促使了铀在汇区内的再迁移,并发生铀成矿作用。文章最后对江西省新一轮铀矿找矿方向提出了建议。

The traditional research on uranium metallogenic geological environment in Jiangxi province was separated reciprocally according to different kinds.This paper study on basic material source of uranium metallogenic based on its temporal and spatial distribution characteristics,then analyzing uranium metallogenic geological environment. It presents the reason of uranium mineralization that magmatism causes such a dynamic process as material moving on the basis of mesozoic structure- magma-？ geodynamies background. At last, the paper provided the suggestion on prospecting prospects in Jiangxi Province.
