| 摘 要： | 通过研究努和廷铀矿床地质特征、成矿作用及地球化学特征,认为努和廷矿床为同生沉积后生改造型铀矿床。晚白垩世二连期湖泊发育区控制了矿床定位。矿床成矿作用经历了同生沉积成矿、后生改造和表生作用3个阶段,成矿年龄为85Ma、（41±5）Ma和6～13Ma。在总结矿床成矿地质特征、成矿作用及地球化学特征基础上,建立了努和廷铀矿床成矿模式。

| Abstract: | Based on the study on geological characteristics,metallogesis and geochemical features in Nuheting uranium deposit,it is considered that the deposit belongs to syn-sedimentary and epigenetic reworking type.The deposit position was controlled by the lake area developed during Erlian period in Late Cretaceous.The metallognesis has experienced three stages,they are syn-sedimentary metallogenesis,epigenetic reworking metallogenesis and exogenic metallogenesis.The ore-forming ages are respectively 85 Ma,（41±5）Ma and 6-13 Ma.Based on the summary of metallogenic geological features,metallogenesis and geochemical features,the metallogenic model of Nuheting uranium deposit has been established. |
