太平洋三海区热液烟囱物的地球化学和氧同位素标型特征研究

The Geochemical and Oxygen Isotope 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 ,运用电子探针、中子活化、常规化学分析和稳定同位素分析等多种地球化学实验测试技术 ,比较系统地研究了太平洋三区四地热液烟囱物的地球化学组成和其变化 ,揭示了研究区不同热液喷发类型中的地球化学标型特征。

Different geochemical testing technique, such as electron probe, neutron activation, conventional chemical and stable isotope analysis,are applied to determine the geochemical components and changes of hydrothermal chimney samples obtained from four areas of the Pacific Ocean. According to the theory and methods of genetic-mineralogy, The geochemical standard type characteristics of these samples formed in different hydrothermal eruptions can be discovered. Therefore, it can come to the conclusion that hydrothermal minerals with different standard type characteristcis have close relationship with the condition of hydrothermal eruptions.
