【摘要】 在五台山金岗库新太古代块状硫化物矿床发现了一些多孔状黄铁矿石标本,经过详细的显微构造鉴别和相关的电子探针分析,发现其中保留的一些特征性显微结构(胶状结构、通道构造、分带构造及淬火构造等)与现代海底硫化物黑烟囱结构构造非常类似,初步得出这些标本为新太古代海底黑烟囱的残片,显示了该矿床黑烟囱模式的海底喷流成因机制。更多还原

【Abstract】 Some specimens of porous sulphide ore are found in the Neoarchean massive sulphide deposits in Jingangku,Wutaishan Mt.Based on the results of the detailed microscopic observation and the analysis of electron probe to the samples,the similar textures and structures,as colloform texture,channel structure,filling structure,zonal structure and so on,with the modern seafloor sulphide chimney are identified.These samples are thought as the relics of the Neoarchean seafloor sulphide black chimneys owing to the above reasons,which indicate the origin of the Jingangku sulphide ore may be contributed to the submarine exhalative model.更多还原
