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 ...

Methods for multiancestry genome‐wide association study meta‐analysis

open access: yesAnnals of Human Genetics, EarlyView.
Abstract Genome‐wide association studies (GWAS) have significantly enhanced our understanding of the genetic basis of complex diseases. Despite the technological advancements, gaps in our understanding remain, partly due to small effect sizes and inadequate coverage of genetic variation.

Thallium Isotope Fractionation During Magma Degassing: Evidence From Experiments and Kamchatka Arc Lavas

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Thallium (Tl) isotope ratios are an emerging tool that can be used to trace crustal recycling processes in arc lavas and ocean island basalts (OIBs). Thallium is a highly volatile metal that is enriched in volcanic fumaroles, but it is unknown whether ...

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 ...

Genome‐wide association study on chronic postsurgical pain after abdominal surgeries in the UK Biobank

open access: yesAnaesthesia, Volume 80, Issue 5, Page 499-510, May 2025.
Summary Introduction Chronic pain is one of the most common and severe complications after surgery, affecting quality of life and overall wellbeing of patients. Several risk factors have been identified but the mechanisms of chronic postsurgical pain development remain unclear.

Disequilibrium Rheology and Crystallization Kinetics of Basalts and Implications for the Phlegrean Volcanic District

open access: yesFrontiers in Earth Science, 2020
Large volcanic eruptions are frequently triggered by the intrusion of hot primitive magma into a more evolved magma-chamber or -mush zone. During intrusion into the cooler mush zone, the basaltic magma undergoes crystallization, which in turn can release

Mapping British Latinx Writing

open access: yesBulletin of Latin American Research, EarlyView.
There are an estimated quarter of a million Latin Americans living in the UK, yet they remain outside the British national imaginary. This invisibility has historically extended to the literary scene and publishing industry, with only very few British‐based Latin American and Latinx writers gaining any exposure.

Magma dynamics

open access: yesEos, Transactions American Geophysical Union, 1991
What are the processes that drive magmatic diversity? How is it that volcanic centers can exist for millions of years erupting a variety of chemical types? What are the means by which large batholithic complexes become assembled? Magmas (silicate melts)differ from other geophysical fluids, such as oceans and atmospheres, in that their physiochemical ...

A History of Andesite Production via Magma Mixing and Mingling Revealed Microscopically at Ngauruhoe Volcano

open access: yesGeochemistry, Geophysics, Geosystems, 2022
Many andesites erupted at arc volcanoes are the products of magma mixing, and this process could be important in triggering their eruption. Throughout the life of Ngauruhoe volcano (∼2.5 ka), erupted andesites lack macroscopic enclaves or lithological ...

Volcanically induced glacier collapses in southern Jan Mayen (Sør‐Jan), Norway

open access: yesBoreas, EarlyView.
A formerly unknown glacier totally covered with tephra was found in an area of Jan Mayen where no Holocene glaciation was known. This glacier and three others in the same area melted abruptly creating jökulhlaups due to volcanic activity impacting the glacier catchments at different times in the Holocene.
