相山盆地基底形态及其与铀矿化的关系探讨

Discussion on the Basement Topoqraphy and It's Relation with the Uranium Mineralization in Xiangshan Basin

通过对相山盆地大比例尺重力资料的正反演计算 ,对相山盆地基底埋深进行了定量分析 ,探讨了相山盆地基底的起伏形态与铀矿化关系 ,认为相山盆地基底形态间的差异 ,是造成区内铀矿化分布不均匀的主要原因 ,基底隆起区边缘附近或基底形态变异部位是铀矿化的有利部位 ,这对指导相山的攻深找盲工作有重要意义。

The depth of the basement and the relation between the basement relief shape and uranium mineralization are discussed by forward and inverse computation for large-scale gravity data in XiangShan basin. The difference of basement topography result in the inhomogeneous distribution of uranium mineralization. The margin of the basement upheaval section and the variation place of basement topography are the favorable place for uranium mineralization. It's helpful to prospect deep and blind uranium deposit in Xiangshan basin.
