Ore Mineral Characteristics of Huangtian Lead-Zinc Deposit in Jian shui of Yunnan
摘要
Abstract
Although China's lead-zinc deposits are distributed in various geological age with com-plete type and complex mineralization , the metallogenic epoch and mineralization period are rela-tively centralized .Thus the study on ore mineral characteristics is of assistance for analysis of de-posit genesis , mineralization and prospecting work .Through systematic study of ore mineral charac-teristics of Huangtian lead -zinc deposit , it is found that main metal minerals of sulfide ore are sphalerite and galena , and main gangue minerals are quartz , dolomite and calcite;main metal min-erals of oxidized ore are smithsonite , hemimorphite and cerussite , and main gangue mineral is quartz .According to geological features , mineral association and mineral metasomatic relations , the generation sequence of main minerals is determined and divided into volcanic sedimentary stage , hydrothermal sulfide stage and supergene stage .Hydrothermal sulfide stage is the main mineraliza-tion stage .In addition , mineralization temperature of sphalerite -galena stage is about 226~290℃, which belongs to mineralization of middle temperature hydrothermal fluid .Therefore, Huang-tian lead-zinc deposit is the result of volcanic sedimentation and postmagmatic hydrothermal trans-formation .关键词
