Mineralogical Study of Hydrothermal Sulfide in the Okinawa Through

The study of hydrothermal sulfide in the Okinawa Through can help to uncover the hydrothermal mineralization characteristics of back-arc basins that are in the early expansion. In this study, the mineralogical characteristics of the sulfide from the midland and south of the Okinawa Through are carried out. First of all, using optical microscope and electron microscope to confirm the mineral composition, characteristics of crystal shape, syntagmatic relation and crystallization order. Analyze the chemical composition in virtue of electron probe.

Near-seafloor Magnetics using AUV URASHIMA at the Tarama and Irabu Hydrothermal Fields, Okinawa Trough

Magnetic mapping is of increasing interest in studies of seafloor hydrothermal systems because such data can promote the understanding of the location and spatial extent of hydrothermal alteration zones. Previous studies reported both reduced and enhanced magnetization at hydrothermal fields of different tectonic settings, suggesting that the destruction and production of magnetic minerals are controlled by geological and tectonic background.
