| 摘 要： | 探讨西藏蒙亚啊铅锌矿床成矿流体来源及其特征,结合区域典型矿床研究厘定矿床成因类型。通过矿床近矿体蚀变灰岩和热液成因方解石碳-氧同位素及成矿不同期次石英氢-氧同位素分析手段,结合流体包裹体岩相学、温度和盐度测试研究,分析了矿床成矿流体的特征及成矿流体来源。结果表明,成矿早期流体以岩浆水为主,成矿晚期有大量天水混入;主成矿期成矿流体总体具有中高温和中低盐度特征,成矿从早期到晚期流体降温趋势明显。矿床形成与岩浆作用关系密切,矿床类型属于远接触端夕卡岩型铅锌矿床。

| Abstract: | The paper studies the source and characteristics of the ore-forming fluids in the Mengya'a Pb-Zn deposit of Tibet and identifies the genetic type of deposit by studying the typical deposit of this area.It analyzes the altered limestone in the surrounding area,the carbon and oxygen isotopes of hydrothermal calcite and the hydrogen and oxygen isotopes of quartz formed in different mineralization periods,studies the fluid inclusions petrographically,and measures their temperatures and salinity.The resuct shows... |
