摘要
Abstract
The Qinglongtan pyrite deposit is situated within a significant metallogenic belt along the northern margin of the Qaidam Basin,characterized by superior metallogenic geological conditions.Although extensive exploration and research have been conducted previously,studies on the evolutionary model of the metallogenic system and integrated prospecting prediction models remain insufficient.This study systematically analyzes the geological characteristics of the deposit,constraints on metallogenic epochs,and multi-stage mineralization processes,combined with structural-lithofacies mapping and geophysical anomaly features.A composite metallogenic model of"volcanic exhalative sedimentation-tectonic modification-skarn superposition"is proposed.Through comprehensive analysis of geological,geophysical,and alteration indicators,a multi-factor prospecting model is established,focusing on key elements including"NW-trending fault-controlled mineralization,ore-hosting volcanic sequences,coupled magnetic-induced polarization anomalies,and greenschist-skarn alteration assemblages."The research outcomes not only deepen the understanding of regional pyrite mineralization mechanisms but also provide novel methodological guidance for the exploration of analogous deposits.关键词
