| [摘要]位于扬子陆块南部被动边缘褶-冲带的滇东铅锌多金属成矿区是我国重要的铅锌多金属
矿产地之一。区内矿床赋矿围岩为震旦系-二叠系碳酸盐岩,以构造控矿为主;成矿过程漫长,成矿元素
来自上下不同层位的地层中,成矿流体具多源特征。本次研究收集了前人关于滇东地区铅锌多金属矿
勘查和研究成果,并利用作者在滇东地区长期从事矿产勘查所获得的资料,探讨了其成矿过程的规律。
该区成矿过程可以分五个阶段:矿床胚胎阶段、早期成矿阶段、矿床发育阶段、晚期成矿阶段和矿床死亡
阶段。 |

| 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. |
