摘要
在综合(以往大量)研究工作成果的基础上,指出我国砂岩型铀矿有着多阶段成矿成因的特点,即沉积-成岩期铀矿化成矿阶段和后生富集期铀矿化成矿阶段,以若干典型矿床为例探讨其成因机制。最后对砂岩型铀矿热液成因说进行评述。
Based on the comprehensive study of the former research information, it is pointed out that sandstone-type uranium deposit is characterized by the multi-stage ore formation, i.e. sedimentary- diagenetic uranium mineralization stage and epigenetic enrichment uranium mineralization stage. The genetic mechanism is discussed by taking several typical deposits as examples. The theory of hydrothermal genesis of sandstone-type uranium deposit is reviewed at the end.
