| 中文摘要: |
| 文章在对沽源盆地内的地质、物化探等信息与铀成矿的关系进行深入分析的基础上，借助MORPAS平台，对区内各控矿要素定量化，利用GIS的空间分析功能提取了断裂Buffer、潜火山岩Buffer、航磁异常等在内的16个证据图层，并将研究区划分为1 km×1 km大小的9 562个单元，利用证据权重法对研究区铀矿进行预测，圈定了3级成矿远景，为该区进一步找矿指出了方向。 |
| 英文摘要: |
| Based on probing the relationship of geological, geophysical and geochemical information of Guyuan basin to uranium mineralization in Guyuan basin, quantification of each ore-control factors in the basin is carried out by means of MORPAS platform. And 16 evidence layers such as fracture buffer, subvolcanic rock buffer and magnetic anomaly are extracted and constructed through spatial analysis of the MORPAS system. The research area has been divided into 9562 units with 1 km×1 km for each unit. Uranium potential is calculated by evidence weight model and 3 class targets are located thus put forward the prospecting direction for further exploration of uranium ore in the basin. |
