【摘要】 限子矿床矿脉石英中分布有密集呈云雾状,灰黑色,负晶形为主的包裹体群。CO₂包裹体丰富,含CaCl₂等钙盐类的子矿物包裹体及有机包裹体发育。特别是还发现有大量流体熔融包裹体,成矿以300～380℃为主,流体呈中性,弱还原环境。寇半沟矿床成因与之类似,本文根据其包裹体特征,初步讨论了该类型矿床成因,并根据包裹体特点对外围矿点石英脉进行了深部成矿预测。更多还原

【Abstract】 Close-spaced foggy inclusion groups, greyish-black in color and microcrystalline in shape, are often recognized in quartz from the Weizi gold deposit. The inclusions are rich in CO₂, and often contain CaCl₂ daughter mineral or organic matter. A number of fluid-melt inclusions are discovered. Ore-formlng temperatures range from 300 to 380℃. Ore fluid is neutral, indicating a slightly reducing environment. The Koubangou gold deposit is similar to the Weizi deposit with respect to the mechanism of formation.In this paper we have established a preliminary metallization model, and predicted the mineralization potential of deep-seated quartz veins in the surroundings.更多还原
