摘    要:对金山韧性剪切带型金矿床石英及方解石中流体包裹体的研究表明:成矿流体具有中低温、低盐度和低密度的特征;富含Ca2 ,Mg2 ,SO42-,CO2等;主要来源有变质热流体、富含有机质的大气降水形成的热流体和深源流体;流体的性质在时间和空间上都有一定的变化,矿床的形成主要是两期流体成矿作用的结果,是热液与构造的耦合;不同种类流体的混合、单一流体不混溶分离作用和盐水体系中有机质的参与是矿床形成的关键因素.

关 键 词:流体包裹体  成矿流体  深源流体  有机质

Abstract:Fluid inclusion studies have been carried out in the Jinshan ductile shear zone type gold deposit. The ore fluid is medium or low in temperature and low in salinity and density. The chemical compositions of inclusions show that the ore fluid is the Ca~(2+)-Mg~(2+)-SO~(2-)_4-CO_(2 )type. The evidences obtained from fluid inclusions indicate that the ore fluids are mainly mixture fluids, which include metamorphic water and meteoric water enriched in organic matter and some anatectic magma water. Fluids characters in time and space are responded to the coupling of hydrothermal activity and structural development. It is considered that the key factors of gold mineralization are of two or more fluids, sole fluid immiscibility, incorporation of organic materials into sea water system.
Keywords:fluid inclusion  ore-forming  anatectic magma fluid  organic matter  Jiangxi province
