在各种沉积环境标志综合分析的基础上,建立于伊犁盆地含矿主岩属冲积扇快速入湖的湿地扇沉积相模式;确立了铀成矿的有利相位;深入研究了层间氧化带特征、卷状矿体的分带特点及铀矿化空间展布规律;应用U-Pb同位素方法,获得了19Ma,12Ma,1.0Ma几个成矿年龄数据;详细地论述了砂岩型铀矿形成的诸多控制因素;总结了该盆地层间氧化带砂岩型铀矿成矿机制及成矿模式。最后,对盆地远景区划分和今后工作提出
Based on the comprehensive analysis of various sedimentary environment signs, the authors established the facies facies facies pattern of wetland fan facies that the alluvial fans of the Yili basin entered the lake quickly, established the favorable phase of uranium mineralization, and studied the characteristics of the interlayer oxidation zone , The zonal characteristics of the ore body and the spatial distribution of uranium mineralization. Several metallogenic age data of 19Ma, 12Ma and 1.0Ma were obtained by using the U-Pb isotope method. The formation of sandstone-type uranium deposits Many control factors are summarized. The metallogenic mechanism and metallogenic model of interlayer oxidation zone sandstone-type uranium deposit are summarized. Finally, the division of the prospective area of the basin and future work are proposed
