Replacement of Ores Recorded by Textures and Chemical Compositions of Sphalerite: An Example From the Furutobe Kuroko Deposit, Akita, Japan

open access: yesGeological Journal, EarlyView.
Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Thick crust, hydrous magmas, and the paradox of voluminous cold magmatism

open access: yesVolcanica, 2021
Andesites are refined and “cold” magmas compared to their basaltic parents, yet large volumes of andesites are generated at continental arcs. We show that large andesitic plutons are favored when arc crust attains a thickness of ~60 km while mafic ...

Monocytes with trained immunity–like signatures are associated with acute anterior uveitis in ankylosing spondylitis

open access: yesInterdisciplinary Medicine, EarlyView.
In ankylosing spondylitis‐acute anterior uveitis (AS‐AAU), trained immunity monocytes (Mono‐TI) differentiate into macrophages in the eye, retaining trained immunity features. Mono‐TI cells secrete pro‐inflammatory cytokines and chemokines, including IL‐1β, TNF‐α, and CCL3.

Time Variation in the Chemical and Isotopic Composition of Fumarolic Gasses at Kusatsu-Shirane Volcano, Japan

open access: yesFrontiers in Earth Science, 2019
Minor seismicity may occur at volcanoes with hydrothermal system before a steam eruption. To forecast any steam eruption, it is indispensable to detect and understand the nature of this shallow seismicity. As the fumarolic gas resides in the hydrothermal

On the mechanism of interaction between strong earthquakes and volcanism in subduction zones

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2022
The relationship between strong earthquakes and powerful volcanism in subduction zones are discussed. It is shown that abnormally strong earthquakes or a group of strong earthquakes and powerful volcanic events or volcanic activation of large areas can ...

Petrology of some oceanic island basalts: PRIMELT2.XLS software for primary magma calculation [PDF]

open access: yes, 2008
PRIMELT2.XLS software is introduced for calculating primary magma composition and mantle potential temperature (TP) from an observed lava composition. It is an upgrade over a previous version in that it includes garnet peridotite melting and it detects ...

Compositional Evolution of Polygenetic Fissure Volcanic Systems: Insights From the Latest Eruptions at Craters of the Moon Volcanic Field

open access: yesGeochemistry, Geophysics, Geosystems, 2023
The Craters of the Moon (COM) Volcanic Field in Idaho is the largest mostly Holocene lava field in the conterminous U.S. and the site of the most recent volcanism in the Yellowstone‐Snake River Plain province.
