| 中文摘要: |
| 楚鲁达坂地区位于大兴安岭火山岩中东段，处于扎兰屯铀成矿远景带中段，区内火山热液活动强烈，铀成矿地质条件优越。本文通过对区内典型铀矿点（82756）矿化特征分析，铀矿化受中酸性火山岩、构造复合控制，与热液蚀变关系密切。结合地质、航放、遥感、化探等资料，对区域成矿条件进行了分析，基于GIS层次分析法，构建了研究区火山岩型铀矿预测评价层次分析模型，预测出火山岩型铀成矿远景区3处，为区域铀矿找矿工作提供了参考。 |
| 英文摘要: |
| The Chuludaban area is located in the middle section of volcanic rocks of Daxinganling and in the middle section of Zalantun uranium metallogenic prospective belt， with strong volcanic hydrothermal activity and superior geological conditions for uranium mineralization. Based on the analysis of mineralization characteristics of typical uranium deposit （82756） in this area， it is found that uranium mineralization is controlled by intermediate-acid volcanic rock and structure complex， which is closely related to hydrothermal alteration. Combined with geological data， aerial data， remote sensing data and geochemical data， the regional metallogenic conditions are analyzed and the metallogenic prediction of volcanic type uranium deposit in the area is completed. The AHP model for volcanic-type uranium deposits was constructed based on GIS， and three uranium prospective sectors were predicted， which provides reference for regional uranium ore prospecting. |
