摘　　要：甘肃红柳河-方山口地区位于甘肃北山地区北部,铀矿资源丰富,分布有红柳河铀矿床、方山口铀-钒-磷矿床和众多放射性异常点带。在对前人资料收集及整理的基础上,梳理铀成矿条件,结合已知典型铀矿床特征研究,建立了碳硅泥岩型铀矿物理-数学预测模型,结合野外地质工作成果,对该区进行了成矿远景区预测,筛选了一级铀矿远景区两片,对研究区下一步开展铀矿资源勘查具有指导意义。The research area is located in the northern part of Beishan area,Gansu province and rich in uranium resources with Hongliuhe uranium deposit,fangshankou uranium-vanadium phosphate deposit and lot of radioactive abnormallies.By collecting and collating the data of predecessors,we studied the characteristics of typical uranium deposits and analyzed the uranium mineralization conditions,established a geophysical-mathematical prediction model for the carbonaceous-siliceous-argillaceous type uranium deposits.With the results of field work,two uranium prospects was predicted in Hongliuhe-Fangshankou area.
