摘　　要：ORGANIC minerogenesis is one of the important studies in the field of low-temperature mineralization. Ithas been well documented that organic matter plays a very important role in the transport, precipitationand enrichment of gold in the process of mineralization of gold deposits. We have found that manyresearches mainly employed the organic geochemical and experimentally geochemical methods to explorethe role of organic matter in minerogenesis. As kerogen is dispersed in ores and possesses microscopic geological characteristics as observed in its inner parts, little information has been developed about the geological phenomena of minerogenesis developed in the inner part of kerogen. We have adopted a variety ofsophisticated microbeam analysis techniques in the study of microscopic metasomatism and characteristicsof gold occurrence developed in the inner parts of kerogen from the ores of the Yata microfine disseminat-
