Intensified continental chemical weathering and carbon-cycle perturbations linked to volcanism during the Triassic–Jurassic transition

Nature Communications, 2022
Direct evidence of intense chemical weathering induced by volcanism is rare in sedimentary successions. Here, we undertake a multiproxy analysis (including organic carbon isotopes, mercury (Hg) concentrations and isotopes, chemical index of alteration ...

Fusible mantle cumulates trigger young mare volcanism on the cooling Moon

Science Advances, 2022
The Chang’E-5 (CE5) mission has demonstrated that lunar volcanism was still active until two billion years ago, much younger than the previous isotopically dated lunar basalts.

Felsic volcanism as a factor driving the end-Permian mass extinction

Science Advances, 2021
Felsic volcanism in South China with Cu, Hg, and S released exacerbated environmental changes that drove the end-Permian extinction.

Global influence of mantle temperature and plate thickness on intraplate volcanism

Nature Communications, 2021
The thermochemical structure of lithospheric and asthenospheric mantle exert primary controls on surface topography and volcanic activity. Volcanic rock compositions and mantle seismic velocities provide indirect observations of this structure.

On impact and volcanism across the Cretaceous-Paleogene boundary

Science, 2020
An impact with a dash of volcanism Around the time of the end-Cretaceous mass extinction that wiped out dinosaurs, there was both a bolide impact and a large amount of volcanism. Hull et al. ran several temperature simulations based on different volcanic

Distribution and morphology of present-day glaciers on Kamchatka

Лëд 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 ...

Upper cretaceous magmatic suites of the Timok magmatic complex [PDF]

Geološki Anali Balkanskoga Poluostrva, 2010
The Upper Cretaceous Timok Magmatic Complex (TMC) developed on a continental crust composed of different types of Proterozoic to Lower Cretaceous rocks. The TMC consists of the magmatic suites: Timok andesite (AT) - Turonian-Santonian, Metovnica

Density structure beneath the Rungwe volcanic province and surroundings, East Africa from shear-wave velocity perturbations constrained inversion of gravity data

Frontiers in Earth Science, 2023
Density perturbations in the subsurface are the main driver of mantle convection and can contribute to lithospheric deformation. However, in many places the density structure in the subsurface is poorly constrained.

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

Journal 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.
