文章阐述了鄂尔多斯盆地东北部砂岩型铀矿成矿地质背景和矿床的基本特征;从铀的来源、迁移和沉淀富集等方面论述了鄂尔多斯盆地东北部砂岩型铀矿成矿机理,认为该矿床形成的铀源、成矿流体和成矿作用具有多元性和复杂叠置性,提出了该铀矿床形成的“叠合铀成矿模式”。
This paper describes the mineralization geological background and basic characteristics of sandstone-type uranium deposits in the northeastern Ordos Basin. The metallogenic mechanism of sandstone-type uranium deposits in the northeastern Ordos Basin is discussed from the aspects of uranium source, migration and sedimentation enrichment. The formation of uranium source, ore-forming fluid and metallogenesis have the characteristics of multiple and complex superimposition, and proposed the “superimposed uranium metallogenic model ” of this uranium deposit.
