Chromitite layers indicate the existence of large, long-lived, and entirely molten magma chambers
Scientific Reports, 2022 The classical paradigm of the ‘big magma tank’ chambers in which the melt differentiates, is replenished, and occasionally feeds the overlying volcanos has recently been challenged on various grounds.

Magma evolution inside the 1631 Vesuvius magma chamber and eruption triggering
Open Geosciences, 2017 Vesuvius is a high-risk volcano and the 1631 Plinian eruption is a reference event for the next episode of explosive unrest. A complete stratigraphic and petrographic description of 1631 pyroclastics is given in this study.

Evolution of Summit Magma Pressure During the 2018 Caldera Collapse at Kīlauea Volcano
Geophysical Research Letters, Volume 53, Issue 21, 16 November 2026.Abstract We utilized geodetic data from the 16 May to 4 August 2018 caldera collapse sequence to refine the geometries and pressure evolution of two summit reservoirs at Kīlauea volcano: the shallower Halema‘uma‘u (HMM) and deeper South Caldera (SC) reservoirs.

, 2009 When people think of molten rock, they automatically think of volcanic eruption and lava flow, but that is only the tail end of magmatic systems. Molten rock begins underground as magma, and its properties determine whether or not the system will end in ...

Peskine Sixfolds and Debarre–Voisin Fourfolds With Associated Cubic Fourfolds
Mathematische Nachrichten, Volume 299, Issue 11, Page 3367-3391, November 2026.ABSTRACT We develop the notion of Peskine sixfolds with associated K3 surfaces and cubic fourfolds and work out numerical conditions for when these associations occur. In discriminant 24, the first family for which there is an associated cubic fourfold, we identify the cubic explicitly.

Preferential Orientations of Subjovian Patera and Northern Hemisphere Mountain Populations on Io
Journal of Geophysical Research: Planets, Volume 131, Issue 11, November 2026.Abstract Io's surface hosts numerous mountains and volcanic paterae generated by processes that occur at depth, including tidal heating and the resultant crustal recycling and subsidence stresses. Global trends in the shape and orientation of surface features could provide insight into these subsurface processes.

Deep magmatic processes of mafic layered intrusions in the Lala mining area, western Sichuan
Dizhi lixue xuebaoObjective Previous studies have shown that many layered intrusions are formed by multiple pulsations of magma. However, little research has been done on whether the magma involved in the pulsation process comes from a single magma chamber or multiple ...
