摘要
塔拉乌苏地区是巴音塔拉凹陷中北部重要的铀成矿远景区。为评价研究区砂岩型铀矿找矿前景,本次采用RaA法、活性炭法等综合放射性测量技术在该地区进行土壤氡浓度测量,以此划分出土壤氡浓度异常分布范围。结果显示,区内存在DQ-1、DQ-2和DQ-3等3片异常区,经后期钻探查证,已发现铀矿化特征,反映该地区铀成矿潜力较大,认为在DQ-1与DQ-2异常区的夹持部位,为有利成矿预测区,具有良好的找矿前景。
Talawusu area is the most significant uranium mineralization vision zone of the Bayintala Depression.In order to evaluate the prospecting potential for sandstone-type uranium deposits,RaA method and activated carbon method were used for the soil radon concentration detection in this research area.Distribution range of soil radon concentration anomaly could be divided by above methods.The result indicated that three abnormal areas are existed in the study area which are DQ-1,DQ-2 and DQ-3.Characteristics of uranium mineralization was verified by drilling,reflecting that the potential of uranium deposits is great.The low-value zone of radon concentration is the favorable metallogenic prediction area which are clamped by DQ-1 and DQ-2 abnormal areas.
