太平洋三海区热液硫化物中黄铁矿的形态标型和矿物标型特征研究

Morphological and Mineral Standard Type Characteristics of Hydrothermal Sulfide in Three Areas of the Pacific Ocean

以成因矿物学的理论和方法,围绕太平洋三区四地海底热液硫化物和烟囱物中黄铁矿为主线的形态标型(扫描电镜)、矿物标型(粉晶X射线衍射法)及矿物组合,揭示了黄铁矿及伴生矿物在不同热液喷发类型中的标型特征,并由此反证了不同标型特征的热液矿物与热液喷发环境相互依存的紧密关系。

In this paper, the theory and method of genetic mineralogy are used to reveal the standard type characteristics of pyrite and its associated minerals of different hydrothermal eruption types, and the hydrothermal and chimney sulfide samples were collected from three areas of the Pacific Ocean. The morphological standard types(scanning electron microscope), mineral standard types(powdered crystal X-ray diffraction method) and mineral assemblage of pyrite and associated minerals in these samples are discussed to confirm that the hydrothermal minerals with different standard type characteristics have close relations to the hydrothermal eruption environments of these minerals.
