Uranium-Gold Coupling Mechanism in Wuyishan Metallogenic Belt:A Case Study of the Aozibei Deposit,Jiangxi Province
摘要
Abstract
The Wuyishan metallogenic belt is an important uranium and polymetallic metallogenic belt in China,and the Aozibei deposit in Jiangxi Province,located in the northwestern part of the Hecao-keng uranium ore field within this belt,is one of the key deposits in southern Jiangxi.To investigate the uranium-gold coupling mechanism of the Aozibei deposit,this study conducts a systematic analysis based on a comprehensive review of previous exploration achievements,integrated with mineralization relationships,distribution characteristics,and geophysical-geochemical exploration data including gamma-ray surveys,210Po sampling,and magnetic surveys.The results indicate that the uranium-gold coupling in this deposit is controlled by multiple factors such as mineralization stages and structure-li-thology.The uranium mineralization zone of phase Ⅳ is a composite high-field area for gold,with a positive correlation between uranium and gold grades,reflecting a strong"cogenetic and syn-process"coupling.In contrast,gold mineralization is not significant in the uranium mineralization zones of pha-ses Ⅰ,Ⅱ,and Ⅲ.Gamma-ray residual anomalies often overlap with gold anomalies,210Po anomalies,and magnetic anomalies,and the multi-parameter overlapping areas are identified as the optimal target zones for combined uranium and gold exploration.This study clarifies the metallogenic association be-tween uranium and gold in the Aozibei deposit,providing theoretical support and practical basis for the combined exploration of uranium and gold in similar deposits within the Wuyishan metallogenic belt.关键词
