江西相山铀矿田成矿有利因素分析

Analysis of the Metallogenetic Favorable Factors of Xiangshan Uranium Orefield in Jiangxi

文章在阐述相山铀矿田区域地质背景的基础上,通过分析矿源层、蚀变特征、热液、构造与成矿作用之间的关系,认为相山矿田铀成矿是在多种成矿有利条件下共同作用的结果。区域富铀地层为铀成矿准备了物质基础;区域蚀变提高围岩渗透性,并促使了铀的迁移、富集;热液是铀迁移的载体;构造对铀矿床的定位与分布起决定性作用。

Based on the elaboration of the Xiangshan uranium orefield regional geological background, through the analysis of the relationship between the ore source bed, alteration characteristics, hydrothermal, tectonics and mineralization, the mineralization of Xiangshan uranium orefield are resulted from the interaction of the various favorable metallogenetic conditions, such as, the regional uraniurn rich strata to be the material basis for the uranium mineralization, the regional alteration to improve the rock permeability, and promote the migration and enrichment of uranium; the hot fluid to be the ean＇ier of uranium migration, the structure playing a decisive role in the location and distribution of uranium deposits.
