DOI: 10.1016/j.epsl.2017.05.036
Abstract: Abstract The timescales over which magmas in large silicic systems are reactivated, assembled and stored remains a fundamental question in volcanology. To address this question, we study timescales from Fe–Mg interdiffusion in orthopyroxenes and Ti… read more here.

DOI: 10.1016/j.oregeorev.2020.103885
Abstract: Abstract Apatite is a ubiquitous mineral in granites and crystallizes from the beginning of magma evolution to the latest magma-fluids transitional stage, and thus, is able to record petrogenetic-metallogenic information. In order to figure out… read more here.

DOI: 10.1093/petrology/egaa049
Abstract: Silicic calderas can evacuate 100 to >1000 km3 of rhyolitic products in a matter of days to months, leading to questions on pre-eruptive melt generation and accumulation. Whereas silicic plutonic units may provide information on the… read more here.

DOI: 10.1126/sciadv.abj1571
Abstract: The occurrence and the style of volcanic eruptions are largely controlled by the ways in which magma is stored and transported from the mantle to the surface through the crust. Nevertheless, our understanding of the… read more here.

DOI: 10.1126/science.ade0347
Abstract: Seismic tomography has provided key insight into Yellowstone’s crustal magmatic system that includes attempts to understand the melt distribution in the subsurface and the current stage of the volcano’s life cycle. We present new tomographic… read more here.

DOI: 10.2113/rgg20194098
Abstract: —The Udina volcanic complex located in the southeastern part of the Klyuchevskoy group of volcanoes in Kamchatka remained dormant for several thousand years, but the magmatic system beneath the area may be awakening judging by… read more here.
