    摘要:

    根据松辽盆地1:100万重、磁数据的处理结果及相关资料的分析,本文对松辽盆地的基底结构进行了划分,对盆地的断裂构造也进行了大胆推断。同时,在总结前人成果的基础上,根据可地浸砂岩型铀矿床的成矿条件,初步预测出盆地的有利成矿远景区。另外,本文提出了在松辽盆地寻找层间氧化带砂岩型铀矿床的同时,还应重视古河道砂岩型铀矿床的勘探工作。

    Abstract:

    According to the processing results of gravity and magnetic data~at a scale of 1:1000,000) and analysis on relative data in Songliao basin,this paper compa rtmentalizes basement structures, and speculates fault structures of the basin. Meanwhile, on the basis of summing up the achievements of predecessors and in th e light of metallogenic conditions of in-situ leachable sandstone-type uranium d eposits, some favourable uranium metallogenic prospects are predicted. In additi on, this paper also puts forward that attention should be paid to the prospectin g of paleochannel sandstone-type uranium deposits, while we prospect sandstone-t ype uranium deposits in interlayer oxidation zone in Songliao basin.
