中文摘要:
      保山地块位于三江特提斯构造域中南段,伴随多次构造转换,地块内发生了从早古生代到中—新生代的多次花岗岩体侵入活动,使得该区形成了复杂而独具特色的成矿系统,成为我国重要的铁—铜—铅—锌—银—汞—锡—稀有金属矿集区。杨梅田铜铅锌多金属矿床位于保山地块西南部,矿床赋矿地层为上奥陶统,矿体呈脉状、透镜状产出于层间断层破碎带中,矿体与围岩界面清楚,产状与地层基本一致。通过开展构造叠加晕测量工作,指示元素分带序列出现异常,加之同一个矿体矿石中金属矿物组合复杂,反映了矿床的形成为多期、多阶段叠加的结果。矿床为一受构造与岩性共同控制的沉积—改造型热液矿床。
英文摘要:
      Baoshan block is located in the middle and south section of Sanjiang Tethys tectonic domain. With many tectonic transformations, many intrusive activities of granite bodies occurred in the block from Early Paleozoic to Mesozoic - Cenozoic, resulting in the formation of a complex and unique metallogenic system and became an important Fe-Cu-Pb-Zn-Ag-Hg-Sn-Rare ore concentration area in China. Yangmeitian Cu-Pb-Zn polymetallic deposit is located in the southwest of Baoshan block. The ore-hosting stratum of the deposit is Upper Ordovician. The orebody occurs in the interlayer fault fracture zone in vein and lenticular shape. The interface between the orebody and the surrounding rock is clear and the occurrence is basically the same as the stratum. By conducting the measurement of tectonic superimposed halos, there was an anomaly in the zoning sequence of the indicator elements. In addition, the complex assemblage of metallic minerals in the same ore body reflected the formation of the deposit as a result of multi-stage and multi-stage superposition. The deposit is a sediment-?hydrothermal?alteration deposit controlled by structure and lithology.
