| 中文摘要:烂泥沟超大型卡林型金（汞、锑）矿床存在有机成矿流体的成矿作用，有机质的来源为含矿地层中的海相藻类等。通过有机包裹体的MPV-Ⅲ法、FTIR法及LRM法的研究，证明成矿流体中有机质主要为成熟度较高的芳香烃和杂原子化合物，以液相的、与水不混溶的形式迁移。成矿流体盐度很低，不是高盐度的油田卤水。矿床的形成与“低温迁移，高韫沉淀”的机制有关。 |

| Abstract:The metallogenic process of the Lannigou superlarge Carlin type gold (mercury, antimony) deposit was related to organic ore-forming fluids, whose organic matter was derived form marine algae in ore-bearing strata. The MPV- Ⅲ, FTIR and I,RM studies of organic inclusions show that the organic matter in the ore-forming fluids consisted mainly of fairly matured aromatic hydrocarbon and polyatomic compounds, which migrated in the form of liquid unmixed with water. The ore-forming fluids had very low salinity and could not form oilfield brine, the formation of the ore deposit was attributed to the mechanism of¨”migration at low temperature and precipitation at high temperature". |
