江西相山铀矿田东西向隐伏构造的发现及其地质意义

本文提出基底EW向构造是相山火山盆地控岩控矿的关键因素，但由于以往缺乏深部研究手段，长期未被人们所认识，前人把贯穿盖层的NE向构造作为基底构造主构造线方向。近年，通过大比例重力测量、遥感TM数据增强处理及深部现代温热水等综合攻深方法的研究，认为相山火山盆地基底存在规模巨大的EW向隐伏构造，首次提出了相山铀矿田EW向构造带控制矿集带的新认识，指出了新的找矿方向，这对相山地区今后寻找富大铀矿具有重要意义。

Discovery of E-W-trending Buried Structure in the Xiangshan Uranium Orefield and Its Geological Significance

E-W-trending basement structure, which is the key rock- and ore-controlling factor in the Xiangshan volcanic basin, has long not been recognized because of lack of thedeep exploration means. Previously the N-E-trending structure going through thecover deep exploration means. Preciously the buried E-W-trending structure going through the coverwas presumed as the principal structural line. In recent years, huge buried E-W-trending structure has been discovered in the basement of the Xiangshan volcanic basin by integrating the large-scale gravity survey, enhancement process of remote sensing TM data and study of modern deep-seated hot water. The author first puts forward a new view that the E-W-trending structure belt controls the ore accumulating zones of the Xiangshan uranium orefieldand points to a new ore-finding direction, which has important significance for the futureexploration of large and high-grade uranium deposits in the Xiangshan area.
