摘　　要：通过对铲子坪矿区地面伽马能谱测量和数据统计,确定了主要地层岩性放射性元素参数,对矿区主要地层的铀、钍、钾元素分布特征和岩性参数进行了深入研究,发现元素与岩石的种类、沉积环境、搬迁过程、变质情况、风化程度等等因素有关。结合地质条件综合分析异常控制因素,对矿床外围成矿潜力进行了评价,确定了成矿有利的岩体和地段,为铀矿资源调查研究工作提供了依据。Based on the ground gamma spectrum measurement and data statistics,the main formation lithology radioactive element parameters are determined.The distribution characteristics of uranium,thorium and potassium elements in the main strata of the mining area and the lithology parameters are studied in depth.It is found that the elements are related to the types of rocks,sedimentary environment,relocation process,metamorphism,weathering degree and other factors.Based on the comprehensive analysis of the geological conditions,the ore-forming potential of the periphery of the deposit is evaluated,and the favorable ore-forming rock masses and sections are determined,which provides a basis for the investigation and research of uranium resources.
