摘要
Abstract
The Pb-Zn polymetallic metallogenic belt in eastern Yunnan,located in the fold-thrust zone along the passive margin of the southern Yangtze continental block,is one of the significant Pb-Zn metallogenic belts in China.In this belt,the country rocks hosting deposits are Sinian-Permian carbonate and mineralization is controlled by structures.The ore forming processes underwent a long period.Ore forming elements originated from upper or lower strata surrounding ore deposits.Ore forming fluids are multi-sources.The Pb-Zn polymetallic metallogenic process is complex.Based on previous Pb-Zn polymetallic exploration and researches and the data accumulated during our long-term field work,we attempt to discover the ore-forming rules in this belt.It is proposed that Pb-Zn polymetallic mineralization of this belt can be divided into five stages,i.e.the embryonic stage,early ore-forming stage,development stage,late ore-forming stage and dead stage.关键词
