兴义某铀矿土壤氡气特征及其找矿应用
Characteristics and prospecting application of soil radon in a uranium mining area,Xingyi City,China
摘要
Abstract
This study aims to further clarify the characteristics of uranium deposits and faults in a uranium mining area in Xingyi City,thereby laying a solid foundation for subsequent drilling operations.Soil radon measurements were conducted using the FD216 environ-mental radon meter.The data obtained were analyzed comprehensively to determine the content and distribution of radon in the soil,delineate the anomaly halos of soil radon,and refine the properties of concealed faults.Furthermore,the metallogenic characteristics of uranium deposits were examined,combined with geological and geochemical exploration data.This study revealed a strong correlation between soil radon content and fault strike.The most significant radon anomaly zones are located in the southwest and central-northeast sides.Uranium deposits in the study area occur in fault fracture zones and are associated with strata.The uranium exploration target might be located within the fault zone in the first member of the Middle-Lower Triassic Jialingjiang Formation.关键词
