The Geochemical and Oxygen Isotope Standard Type Characteristics of Hydrothermal Sulfide in Three Areas of the Pacific Ocean

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.
