| Abstract: | Studies of submarine hydrothermal deposits indicate that the deposits not only form intermittently along the world's Mid-Ocean Ridge system, but also occur in association with submarine volcanism in some island arcs. These deposits have received a great deal of attention. Therefore, hydrothermal mineralization at sea floor spreading centers is one of the most active subjects in the international geoscience.
From July to August of 1990, the author had the opportunity of attending the hydrothermal mineral occurrence investigation in the Mariana back-arc basin organized by German-Amercian cooperation ("Sonne"69 cruise). This paper has described; (1) historical development of hydrothermal polymetallic ore deposit investigations; (2) sea floor exploration methods in the 90's; (3) the occurrence of these deposits; (4) sea floor hydrothermal mineralizat-ion; (5) high-intensity hydrothermal activity and geologic events and (6) shape of deposits and fluid dynamics.
The author suggests that great attention should be paid to hydrothermal deposits in carrying out a survey for polymetallic nodule resources in the Pacific. |
