赣南高山角斑岩型钨钼矿化新发现与找矿潜力分析
New discovery and prospecting potentiality of Gaoshanjiao porphyry type W-Mo mineralization in southern Jiangxi Province
摘要
Abstract
The southern Jiangxi region,renowned as the"Tungsten Capital of the World",is characterized by concen-trated occurrences of quartz vein-type tungsten polymetallic deposits.Recently,the first porphyry-type tungsten-molybdenum ore body was discovered in the Gaoshanjiao mining area of the Yinkeng ore field,southern Jiangxi.This thick ore body exhibits veinlet-disseminated texture and occurs in both exo-and endo-contact zones of the Gaoshanjiao granodiorite porphyry.It demonstrates characteristic porphyry-type alteration zoning including silici-fication,K-feldspar alteration,chloritization,sericitization,and carbonatization.The discovery of the Gaoshanjiao tungsten-molybdenum deposit provides new prospecting insights for the eastern segment of the Nanling metallo-genic belt and holds significant implications for regional metallogenic studies.Based on detailed geological inves-tigations,this study systematically documents the alteration zoning characteristics and geophysical-geochemical anomalies.LA-ICP-MS zircon U-Pb dating yields a weighted mean age of(157.01±0.87)Ma for the ore-hosting granodiorite porphyry,consistent with the metallogenic epoch of widespread tungsten-tin deposits in southern Ji-angxi.Geochemical analysis reveals that except for slightly lower SiO2 content(66.21％～69.55％),other charac-teristics of the ore-bearing porphyry align well with those of typical global porphyry tungsten-molybdenum de-posits.Integrated regional metallogenic analysis and drilling data suggest that the Gaoshanjiao deposit has poten-tial to develop into a large-scale tungsten-molybdenum resource.关键词
