In this paper, mineralogical characteristics and genetic mechanisms of silicatecarbonatesulfate spherulites in mafic veins in Guocheng gold deposit in Jiaodong Peninsula have been studied. Through integrated mineralogical, textural and geochemical analysis, many types of silicatecarbonatesulfate spherulites with complex compositions and textures have been identified. It will provide a new perspective for understanding the properties and sources of ore-forming fluids. It is shouwed that the origin of the chondrules in the two types of veins is different, and the cloud clinopyroxene may be derived from silicate magma in the mantle and formed through magma immiscibility. The clinopyroxene may be a product of multi-stage hydrothermal metasomatism.
