Publikováno v: Minerals, Vol 14, Iss 3, p 259 (2024)
The experimental study of water–rock reactions under high-temperature and -pressure conditions is a useful approach to constrain controlling factors of the fluid composition in a natural hydrothermal system. Previous studies have focused mainly on

Abstract Submarine hydrothermal deposits are one of the promising seafloor mineral resources, because they can store a large amount of metallic minerals as sulfides. The present study focuses on the electrical properties of active modern submarine hy

Since the initial discovery of hydrothermal vents in 1977, these ‘extreme’ chemosynthetic systems have been a focus of interdisciplinary research. The Okinawa Trough (OT), located in the semi-enclosed East China Sea between the Eurasian continent

Origin of orthopyroxene-bearing felsic gneiss from the perspective of ultrahigh-temperature metamorphism: an example from the Chilka Lake migmatite complex, Eastern Ghats Belt, India
Autor: Kaushik Das, Junji Torimoto, Daniel J. Dunkley, Sankar Bose
Publikováno v: Mineralogical Magazine. 84:712-737
Orthopyroxene-bearing felsic gneiss occurs as foliation-parallel layers and bands together with aluminous granulite, mafic granulite, and quartzofeldspathic granulite in the Chilka Lake migmatite complex of the Proterozoic Eastern Ghats Belt, India.

Publikováno v: Mineralium Deposita.
Artificial hydrothermal vents, created by boreholes that discharge hydrothermal fluids and useful for observing secular changes in mineral precipitates and the chemical compositions of hydrothermal fluids, are periodically cleaned of scale deposits.

Thermal expansion of natural mantle spinel using in situ synchrotron X-ray powder diffraction
Autor: Yoshinori Tange, Junji Torimoto, Yuji Higo, Junji Yamamoto, Daisuke Yamazaki, Takashi Yoshino
Publikováno v: Journal of Materials Science. 54:139-148
We used in situ measurements of X-ray diffraction patterns in a cubic multi-anvil press at pressures up to 3 GPa and at 500–1300 K to examine thermal expansion and its pressure dependence in (Mg0.73Fe0.27)(Cr0.56Al1.44)O4 spinel separated from a ma
