宁安盆地构造演化与找铀矿远景预测

The structural evolution and prognosis of uranium exploration in Ning'an basin

笔者在前人工作的基础上,通过对宁安盆地区域地质背景分析,划分了宁安盆地构造演化阶段,并探讨其形成机制,进而分析了宁安盆地砂岩型铀矿的成矿条件,结合已有的铀矿化信息,预测盆地的产铀远景,指出了盆地内进一步找铀矿的方向。

Based on the researches of Ning＇an basin, the tectonic evolution stages have been divided and its formation mechanism has been discussed through analyzing the regional geological setting of Ning＇an basin. Furthermore, metallogenic conditions for sandstone-type uranium deposits have been studied. Combined with the uranium mineralization information available, uranium-producing prospect areas have been predicted, direction for further uranium prospecting has also been pointed out.
