| 摘 要： | 分析了松辽盆地在喜山旋回中所处的应力场、喜山期构造运动及所产生的地貌环境,认为喜山期构造运动为松辽盆地砂岩型铀矿形成创造了有利的构造地貌条件,主要成矿时间为始新世、上新世。松辽盆地南部盆缘剥蚀天窗区构造发育,成矿作用明显,是寻找地浸砂岩型铀矿的有利地段。

| Abstract: | Based on the analysis of stress field and geomorphic environment of Songliao Basin during Himalayan Movement,it is presented that Himalayan Movement supplied favorite structural and geomorphic conditions with Eocene and Pliocene being metallogenic epoch for sandstone-type uranium in Songliao Basin. Degradation inliers at the southern margin of Songliao Basin,where structure and mineralization developed well,are the target area for in-situ sandstone type uranium. |
