Geochemical characteristics of hydrothermal fluids at Hatoma Knoll in the southern Okinawa Trough
hydrothermal fluid Hatoma Knoll Okinawa Trough phase separation sediment subducting material
2017/4/10
Chemical and isotopic compositions of hydrothermal fluids from Hatoma Knoll in the southern Okinawa Trough were
investigated. The hydrothermal fluids were derived from a single pure hydrothermal flui...

The aim of this study was to understand geochemistry of thermal fluids circulating in the basin at the southwest of
Tekman (Erzurum, Turkey) Geothermal Province in Eastern Anatolia as well as to esti...
Dissolution processes of elements from subducting sediments into fluids: Evidence from the chemical composition of the Sanbagawa pelitic schists
element mobility subduction zones pelitic schists
2017/4/12
In order to evaluate the dissolution processes of elements from subducting sediments into fluids during early stages of
metamorphism (up to oligoclase–biotite zone at about 30 km depth), the chemical...
Stable and noble gas isotopic study of thermal and groundwaters in northwestern Hokkaido, Japan and the occurrence of geopressured fluids
geopressured fluid hydrogen isotope oxygen isotope helium isotope Hokkaido
2017/8/9
Thermal and groundwaters are distributed along the west coast and in the inland region of Northwestern Hokkaido, Japan. The waters in the latter group have relatively high temperatures. Stable (D, O) ...
