摘要
Abstract
Based on previous geological exploration data from a certain lead-zinc mining area in Yunnan,this study investigated the structural types,alteration mineral assemblages,and characteristics of ore-forming fluids within a specific ore belt.The results indicate that two sets of fault structures,oriented NE-SW and NW-SE,in the mining area provided conduits for the migration of ore-forming fluids.The alteration mineral assemblages primarily consist of dolomite-ankerite,calcite-ferrocalcite,and pyrite,among others.The ore-forming fluids belong to a mesothermal to epithermal hydrothermal system with moderate temperatures(100～250 ℃)and low salinity(0.5％～10％).Structural-alteration processes represent the key mechanism for the enrichment of the ore belt.This study provides a basis for further revealing the metallogenic mechanism of the ore belt and delineating deep prospecting targets.关键词
