Regional Metallogenic Characteristics and Regularities of the Anhui-Zhejiang-Jiangxi Border Igneous Belt
摘要
Abstract
The Anhui-Zhejiang-Jiangxi border igneous belt is situated at the junction of the Yangtze and Cathaysia Plates,where tectonic and Yanshanian magmatic activities are well developed,and gold,lead-zinc,tungsten,molybdenum and other polymetallic deposits(occurrences)are widely distributed.Based on a systematic review of regional deposit types and their distribution patterns,this paper analyzes the control of strata,structures and magmatic rocks on mineralization,and explores the sources of ore-forming materials and fluids using fluid inclusion and isotopic geochemical methods.A"shear zone-magmatic hydrothermal"mineralization model is then constructed.The study suggests that mineralization is controlled by NE-trending ductile-brittle shear zones and Early Yanshanian(~141 Ma)high-K calc-alkaline granites.The main ore-forming materials are derived from deep magmatic hydrothermal fluids,with partial contributions from the assimilation of shallowly metamorphosed basement rock series.Regional mineralization exhibits a distinct zonation characterized by"structure-controlled belts,intrusion-controlled rocks,and alteration-controlled ores".This research provides a theoretical basis for the new round of mineral exploration.关键词
