| 摘 要： | 鱼卡金矿成矿流体的包裹体以富液相的气液两相（不同的CO2和H2O比）包裹体为主,属于中深层成矿环境的中低温造山型金矿。在综合分析鱼卡金矿的矿床地质特征基础上,从成矿流体包裹体的运移角度出发,通过成矿流体的物理化学参数变化以及流体包裹体面分析认为矿体的形成和空间分布受流体输导系统的控制;鱼卡金矿成矿流体总体从南东向北西运移,局部发生侧向运移,流体中心具有高温多期的特征;钻探施工证实矿体具有向南东侧伏的情况,成矿流体中心位于矿区南东部,即表明基于成矿流体包裹体研究指导金矿床的勘探工作有效。

| Abstract: | Yuka gold deposit is a medium-low temperature orogenic gold deposit formed in medium depth environment with fluid inclusion dominated by liquid and CO2-H2O phase and variable ratios of CO2/H2O. According to the geological characteristics, migration and variation of physical-chemical parameters and analysis of the integral distribution face of the fluid inclusions it is considered that formation of the ore body and the spatial distribution is controlled by conductive system of the ore fluid. Generally the ore fluid moved from SE to NW with local lateral flow and the center is characterized by multi-phase fluids. Drilling detected SE pitch of ore body. Center of the ore fluid is located at southeast part of deposit area coinciding with study of the fluid thus exploration of the deposit can be guided by results of the study. |
