Volcanism and Deep Structures of the Moon

open access: yesSpace: Science & Technology, 2023
Volcanism is the most important endogenic geological process of the Moon, which is closely related to its internal structure and thermal history. Lunar volcanism is one of the most important topics for lunar science and explorations. Recent lunar orbital

Age of Initial Submarine Volcanism in the Paleo-Tsushima Basin and Implications for Submarine Volcanism in the Opening Stage of the Japan Sea in Northern Kyushu

open access: yesGeosciences, 2021
The Tsushima Lapilli Tuff, the thickest tuff in the Taishu Group on Tsushima Island, underwent a thermal event after deposition, and has not previously yielded a reliable age because various ages have been reported.

Constraints on the Production of Phosphine by Venusian Volcanoes

open access: yesUniverse, 2022
The initial reports of the presence of phosphine in the cloud decks of Venus have led to the suggestion that volcanism is the source of phosphine, through volcanic phosphides ejected into the clouds. Here, we examine the idea that mantle plume volcanism,

Distribution and morphology of present-day glaciers on Kamchatka

open access: yesЛëд и снег, 2020
The current glacierization of the Kamchatka Peninsula includes 643 glaciers with a total area 769.48±48.34 km2. A variety of combinations of macro-relief factors, climate and volcanism caused irregular distribution of glaciers on the Peninsula, as well ...

Synthesis of global satellite observations of magmatic and volcanic deformation: implications for volcano monitoring & the lateral extent of magmatic domains

open access: yesJournal of Applied Volcanology, 2018
Global Synthetic Aperture Radar (SAR) measurements made over the past decades provide insights into the lateral extent of magmatic domains, and capture volcanic process on scales useful for volcano monitoring.

U-Th-Pb zircon geochronology on igneous rocks in the Toija and Salittu Formations, Orijärvi area, southwestern Finland: Constraints on the age of volcanism and metamorphism [PDF]

open access: yesBulletin of the Geological Society of Finland, 2008
Zircons from a felsic volcanic rock in the Toija Formation and a synvolcanic gabbro intrusion in the Salittu Formation within the Orijärvi area were dated by U-Th-Pb SIMS in order to provide depositional constraints on these formations.
