西准噶尔地区位于中亚成矿域核心区,发育众多斑岩型矿床,具有较大的找矿潜力。以斑岩型铜钼矿床为代表,矿床的形成和岩浆-热液流体的活动密切相关。流体的氧化还原性质对成矿物质的迁移、富集具有重要影响,一定程度上控制着矿床的品位和规模。西准噶尔地区斑岩型铜钼矿的成矿流体较多的呈现出还原性,可能是限制了矿床规模的原因之一。
The West Junggar region is located in the core area of Central Asia metallogenic area and has a large number of porphyry deposits, which has great prospecting potential. Taking the porphyry copper-molybdenum deposit as the representative, the formation of the deposit is closely related to the activity of the magma-hydrothermal fluid. The redox properties of fluids have an important influence on the migration and enrichment of ore-forming materials and to a certain extent control the grade and scale of the deposits. The ore-forming fluid of the porphyry copper-molybdenum ore in the West Junggar region shows more reducibility, which may be one of the reasons that limit the ore deposit size.
