摘要/Abstract

摘要： 　以巴仁扎拉格铀铌矿床为例，分析了Ｔｈ放射性干扰测井解译结果的原因，探讨了Ｔｈ干扰修正系数的计算方法，并依据赋矿岩体的蚀变特征及矿体埋深讨论了Ｔｈ干扰修正系数的分布特征。该系数的取得可为内蒙古巴仁扎拉格铀铌矿床放射性测井数据修正、矿体边界划分、铀矿资源量计算提供科学依据。

Abstract: Taking Barenzhalage UNb deposit in Inner Mongolia as the study example,the reason the the the logging interpretation results is interfered by Th radioactive,the computation method of Th interference modification coefficient of gamma ray logging is discussed,besides that,the distribution characteristics of Th interference modification coefficient of gamma ray logging is studied based on the analysis of the alteration characteristics of orebodies or rock mass bodies and orebody depth.The calculation method of thorium interference modification coefficient of gamma ray logging proposed in this paper can provide some reliable reference for the radioactive logging data modification,division of orebody boundary and calculation of uranium resources reserves of Barenzhalage UNb deposit in Inner Mongolia.

Key words: Nb deposit, Th interference modification coefficient, Gamma ray logging interpretation
