| 文章简述了喀拉扎地区地质概况、成矿岩性特征及成矿岩层物性参数特征。根据喀拉扎地区地质特点、成矿类型、含矿岩体地层与背景地层物性参数上存在较大差异性,及钙质砾岩与铀矿化正相关性,选取可控源音频大地电磁测量、地面伽玛能谱测量、伽玛总量路线调查及综合测井的勘探方法,并分别说明单一方法在喀拉扎地区的找矿应用及效果,最后综合分析了方法组合在该地区找矿中的应用效果,认为白垩系下统清水河组(K1q)为该区的铀成矿有利地层,钙质砾岩为主要含矿岩体。 |
| 英文摘要: |
| The geological,lithological characteristics of host rock and physical parameters in the Kalazha uranium area were briefly described. Based on geological setting, metallogenic types, and apparent physical parameter differences between ore-bearing rock and background rock, and the positive correlation between calcareous conglomerate and uranium mineralization in the Kalazha area,the controllable source audio frequency magnetotelluric survey, ground gamma spectrum measurement, gamma total route survey, and comprehensive logging exploration methods were selected. The paper firstly introduced the application of each geophysical method and the prospecting effect in Kalazha area, then combined geophysical methods and application effect were comprehensively discussed. The application results suggested that the lower Cretaceous Qingshuihe formation (K1q) was the favorable formation for uranium mineralization, and the calcareous conglomerate was main ore-bearing host rock. |
