新疆伊犁盆地铀成矿特征及其形成地质条件

Discussion on Uranium Metallogenic Feature and its Forming Geological Conditionsin Yili,Xinjiang

本文通过对伊犁盆地区域地质、地貌景观、地层、构造特征的描述，和对铀成矿地质特征的概括归纳，分析总结出了盆地内铀矿床形成的基本地质条件：它们是丰富的铀源、良好的地层结构和砂体、规模较大的斜坡带等基础条件；造山运动是成矿作用的驱动力；

This paper describes regional geology,geomorphologic landscape, strata and structural feature,and summarizes and concludes uranium metallogenic geology feature in Yili basin.Based on above, the basic geological condition of uranium deposit forming is analysised within Yili basin.These condition such as plentiful uramum resouree,good strata texture and sandstone body lange-scale clinoslope zone ete.uranium metallogenic basic condition;mountain-building move-ment is mineralization dy nimic;but Cretaceous and Tertiary system sandy xonglomerate layer xovering uranium depost is the most importance condition of uranium deposit location
