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.

A uniform isotopic and chemical signature of dust exported from Patagonia: Rock sources and occurrence in southern environments [PDF]

open access: yes, 2007
Patagonia is considered to be the most important source of dust from South America that is deposited in surrounding areas, and we present here a systematic Sr and Nd isotopic study of sediment currently being exported.

Late Ordovician mass extinction caused by volcanism, warming, and anoxia, not cooling and glaciation: REPLY

open access: yesGeology, 2020
The Ordovician saw major diversification in marine life abruptly terminated by the Late Ordovician mass extinction (LOME). Around 85% of species were eliminated in two pulses 1 m.y. apart.

Traces of explosive volcanic eruptions in the Upper Ordovician of the Siberian Platform [PDF]

open access: yesEstonian Journal of Earth Sciences, 2014
Ordovician K-bentonite beds have a long history of investigation all around the world. They have been reported from Gondwana, the Argentine Precordillera, the Yangtze Platform, Laurentia, Baltica, and numerous terrains between Gondwana and Baltica, which

Deep Learning Investigation of Mercury’s Explosive Volcanism

open access: yesRemote Sensing, 2023
The remnants of explosive volcanism on Mercury have been observed in the form of vents and pyroclastic deposits, termed faculae, using data from the Mercury Atmospheric and Surface Composition Spectrometer (MASCS) onboard the Mercury surface, space ...

Observing eruptions of gas-rich compressible magmas from space

open access: yesNature Communications, 2016
Satellite observations are an important tool in volcano monitoring, but observations such as ground deformation and gas emissions are treated independently. Here, the authors present a model coupling them through their link to magma volatile contents and

The eruptive tempo of Deccan volcanism in relation to the Cretaceous-Paleogene boundary

open access: yesScience, 2019
Two timelines for extinction The Cretaceous-Paleogene extinction that wiped out the nonavian dinosaurs 66 million years ago was correlated with two extreme events: The Chicxulub impact occurred at roughly the same time that massive amounts of lava were ...
