| 摘 要： | 本文从研究国外超大型铀矿床特征和分类入手，总结其铀成矿地质条件，结合我国北西部地质特征、矿化分布特点，认为我国北西部今后寻找超大型铀矿床主要是中新生代可地浸的层间氧化带砂岩型铀矿，其次是伟晶花岗岩型、火山岩型及奥林匹克坝型（即隐爆角砾岩型）的铀矿床。

| Abstract: | Starting with. the study on the characteristics and classification of foreign superlarge uranium deposits, summarizing their metallogenetic gological conditions and on the basis of geological characteristics and features of mineralization distribution in the northwestern part ofChina, it is considered in this paper that prospecting for superlarge uranium deposits therefrom now on should be aimed at Mesozoic and Cenozoic sandstone type uranium deposits ininterlayer oxidation zone(in-situ leachable) and pegmatitic granite type, volcanic type andOlympic Dam type (i. e. cryptoexplosive breccia type)uranium deposits. |

| Keywords: | Superlarge uranium deposit In-situ leach mining Pegmatitic granite type |
