Keyword:  遥感航测岛弧构造系构造阶地层间氧化带找矿模式;
Abstract: 本文以遥感图像和实践资料为依据,以区域地质构造研究为中心,主攻大型可地浸砂岩型铀矿.运用板块构造理论,对伊犁盆地铀矿成矿地质背景、区域地质构造特征、控矿机理、控制因素和成矿规律等方面进行综合分析研究.提出了在天山古岛弧系中,伊犁多相地块之上中新生代压扭性断拗盆地内稳定地块与特定的古地理环境及其"构造阶地①",共同控制层间氧化带大型砂岩型铀矿的新观点,并将"水液型"砂岩型铀矿的成因归结为"双合"式铀成矿模式及其"八位一体"的找矿模式,为近期开发大西北,持续寻找和预测大型砂岩型铀矿提供了新的线索,明确了方向.
