【摘要】 根据遂川—热水走滑断裂及其拉分叠接带的鹿井铀矿田的地质构造、矿化特征和产铀花岗岩中生热元素的平均含量 ,对矿田内花岗岩的放射性衰变热进行了初步的计算。结果表明 ,放射性衰变热可能是鹿井矿田主要的成矿热源之一。据此可对矿田的矿床地质和矿化特征作出合理的解释。更多还原

【Abstract】 Based on the geology and tectonics of the Suichuan Reshui strike slip fault zone(SRF),and the Lujing uranium ore field located in the pull apart stepover of SRF,and abundances of heat producing elements(U,Th,K) of the Yanshanian granite hosting the uranium deposits,the radiogenic heat of the granite is calculated.This calculation suggests that radiogenic heat is possibly the main heat source necessary for the hydrothermal uranium mineralization in the ore field.The basic geological and mineralization features of the uranium deposits can be well understood,with the radiogenic heat considered to be a main and favorable agent of mineralization.更多还原
