Metallogenic Model and Prediction of Granite-type Uranium Deposits in Zhuguangshan Pluton
摘要
Abstract
Zhuguangshan pluton is the most significant granite-type uranium ore-concentrated area in China,hosting two major uranium orefields and numerous deposits.However,due to the pluton's vast scale,historical exploration and research efforts have been fragmented and compartmentalized across different administrative or geological units.This has significantly constrained the depth of systematic investigation into the granite-type uranium mineralization across the entire pluton.Focusing on the granite-type uranium deposits of Zhuguangshan pluton,this study investigates the H-O and C-O isotopic signatures of fluid inclusions from representative deposits.The results indicate that the ore-forming fluids originated from a mixture of mantle-derived fluids and meteoric water,implying a multi-source origin for the ore-forming components.The genetic type of these deposits is defined as polygenetic hydrothermal deposits involving deep mantle fluids and meteoric water.Uranium deposits are mainly controlled by faults,hydrothermal alteration,late-stage small intrusions and dikes,as well as various types of geological interfaces,with fault structures being the most critical ore-controlling factor.Based on a comprehensive analysis of the metallogenic setting,characteristics of mineralization,metallogenic mechanisms,and ore-controlling factors,this study establishes a four-stage regional uranium metallogenic model for Zhuguangshan pluton.Furthermore,39 prospective areas for uranium exploration have been delineated,and the prospecting types and favorable locations within six metallogenic belts are specified.These results provide a scientific basis for guiding future uranium exploration strategies in Zhuguangshan pluton.关键词
