| 摘 要： | 内蒙古扎兰屯地区位于大兴安岭成矿带中段,受植被覆盖厚、自然地理条件复杂、工作程度低等因素影响,铀矿找矿进展较为缓慢。在对扎兰屯地区典型铀矿点控矿因素剖析的基础上,对航放、化探异常、遥感多源铀成矿信息进行了分析,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,预测铀成矿远景区7处,其中2处尚未发现铀矿床(点),其成矿地质条件优越,成矿信息丰富,具有较好的找矿前景。

| Abstract: | Zhalantun area in Inner Mongolia is located in the middle part of Daxing’an Mountains metallogenic belt.Restricted by the thick cover and complex natural geographical conditions,uranium prospecting degree is relatively slow.Multi-source information of ore-controlling factors for typical uranium deposits was analyzed in aerial gamma-ray spectroscopy,geochemistry and remote sensing,the AHP model for volcanic-type uranium deposits was constructed based on GIS,and seven uranium prospective sectors were predicted,and two of them are brand new target which have excellent geological conditions,rich prospecting clues of metallization. |
