狼山地区广泛分布着花岗岩型铀矿化和砂岩型铀矿化。本文通过对该区的遥感地质综合解译,重点研究了几个含铀盆地的砂岩型铀矿化成矿特点及其通感图象的影象特征,发现广布于早白垩世断陷盆地的砂岩型铀矿化是一典型的层控型铀矿。并通过区域构造型式的研究,强调了弧形构造的断块活动特征及其对含铀盆地和含矿层分布的控制作用;揭示了弧形构造的后期活动和环形构造、北北东向线性构造与铀矿化的再造关系。从而得出砂岩铀矿化是受地层岩相和弧、环、线构造“四位一体”条件控制的新认识。该矿化在MSS图象上呈现一定的影象特征,据此,本文概括出本区层控铀矿的影象模式。
Langshan area is widely distributed granite-type uranium mineralization and sandstone-type uranium mineralization. Based on the comprehensive interpretation of the remote sensing geology in this area, the authors focus on the mineralization characteristics of several sandstone-type uranium mineralizations and the image features of the imagery of the sense of increscence in the uranium-bearing basins. It is found that the uranium mineralization is widespread in the Early Cretaceous rift basin Sandstone-type uranium mineralization is a typical stratiform uranium deposit. Through the study of regional tectonic types, the active fault features of arc-shaped faults and their control over the distribution of uranium-bearing basins and ore-bearing formations are emphasized. Late-stage activities and ring structures of arcuate structures are revealed. The north-north eastward linear structure Reconstruction with uranium mineralization. It is concluded that the uranium mineralization of sandstone is a new understanding under the control of “four in one” conditions of lithofacies and arcs, rings and lines in the strata. The mineralization shows certain image features on the MSS images. Therefore, the paper summarizes the image modes of uranium deposits in the area.
