Laser-ablation ICP-MS analysis of silicate and sulfide melt inclusions in an andesitic complex II: evidence for magma mixing and magma chamber evolution [PDF]
, 2018 Laser-ablation microanalysis of a large suite of silicate and sulfide melt inclusions from the deeply eroded, Cu-Au-mineralizing Farallón Negro Volcanic Complex (NW Argentina) shows that most phenocrysts in a given rock sample were not formed in ...

Volcanic Ash Affected by Lightning During the Hunga 2022 Eruption
Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.Abstract The 15 January 2022 eruption of Hunga volcano (Kingdom of Tonga) produced the most lightning ever documented during an explosive eruption to date. This study estimates the mass of erupted tephra that may be structurally or electromagnetically affected by the lightning, based upon lightning peak current, channel length, and ash plume particle ...

Timescales of magma mixing and magma recharge
, 2011 Die Vorgänge in komplexen magmatsichen \(\it plumbing\) Systemen zu verstehen, ist eine der wesentlichen Aufgaben der modernen Vulkanologie. In dieser Arbeit wurde ein Methode entwickelt und getestet, die es ermöglicht chemische Zonierungen in magmatischen Mineralen (Olivin) zu benutzen, um die Aufstiegspfade und die Interaktionen chemisch ...

Arc Magmas from Slab to Eruption: The Case of Kliuchevskoy Volcano [PDF]
, 2011 Arc magmas are generated by a number of mantle and crustal processes. Our multidisciplinary, long-term research is aimed at deciphering these processes for a single arc volcano, Kliuchevskoy volcano in Kamchatka. Some key results of the study follow:

Workshop on Moon in Transition: Apollo 14, KREEP, and Evolved Lunar Rocks [PDF]
Lunar rocks provide material for analyzing lunar history and now new evaluation procedures are available for discovering new information from the Fra Mauro highlands rocks, which are different from any other lunar samples.

Magma mixing in Vulcanello (Vulcano Island, Italy)
, 2008 La actividad volcánica de Isla Vulcano comienzó aproximadamente hace 350.000 años y continúa hasta la actualidad con el desarrollo de tres grandes episodios correspondientes a las caldera de Piano, caldera de Fossa y a Vulcanello, que han emitido piroclastos y coladas de composiciones muy variadas, desde riolitas a traquibasaltos.

Connecting with tephras: principles, functioning, and applications of tephrochronology in Quaternary science [PDF]
, 2013 Tephrochronology is a unique method for linking and dating geological, palaeoecological, palaeoclimatic, or archaeological sequences or events. The method relies firstly on stratigraphy and the law of superposition, which apply in any study that connects
