| 摘 要： | 本文系统研究了哀牢山金矿带主要金矿床主成矿阶段石英流体包裹体的化学组成和物理化学性质。结果表明，金成矿流体中的阳离子主要为Ｎａ＾＋、Ｋ＾＋，阴离子主要为Ｃｌ＾－，ＳＯ４＾２－，Ｆ＾－，气相组分中ＣＯ２含量普遍偏高，成矿流体属于中低温，中性－弱碱性，具相对还原性，中等含盐度的Ｎａ质溶液，其中的金主要以硫氢配合物形式迁移。

| Abstract: | The study of composition and physico-chemical characteristics of fluid inclusions from three gold deposits hosted in the Ailaoshan gold mineralization belt indicated that the ore-forming fluid was characterized as being rich in Na+, K+, Cl-,SO2-4,F-and CO2, and belongs to the Na type solution, epi- to mesothermal in nature, moderately saline, intermediate to weak alkaline, and relatively reducing. Gold in the ore-forming fluid was dominantly transported in the form of bisulfide complexes. |
