新疆伊犁盆地南缘侏罗系层间氧化带发育条件及铀矿远景评价

本文通过对中国新疆伊和犁盆地南缘侏罗系层间氧化带发育条件的分析研究，提出了双重铀源，岩相古地理相变带，水动力机制及地球化学分带控制了层间氧化带及铀化形成的观点，对盆地南缘层间氧化带形成机制进行推论，并据此作了远景评价。

DEVELOPMENTAL CONDITION AND PROSPECTIVE ASSESSMENT FOR THE INTERLAYER OXIDATION ZONE IN JURASSIC AT THE SOUTHERN MARGIN OF YILI BASIN; XINJIANG

Based on the analysis and study on the developmental condition for the interlayer oxidation zone in Jurassic at the southern margin of Yili Basin, Xinjiang,China,this paper presentsthe following controlling factors for the formation of interlayer oxidation and uranium mineralizations,such as double uranium sources,paleogeographic zone of lithofacies changing,hydrodynamic mechanism and geochemical zonation. The formational mechanism of the interlayer oxidation zone at the southern margin of the Basin is deduced and the prospective assessment is made thereafter.
