Modulation of magmatic processes by CO2 flushing
TL;DR: In this paper, the authors investigated the effect of gas injection on the stability and chemical evolution of subvolcanic systems and found that CO2 flushing is a widespread process in both felsic and mafic systems.

TL;DR: In this article, a suite of single-phase amphibole and clinopyroxene thermobarometers and chemometers, calibrated using machine learning, were used to track the range of pre-eruptive conditions over the course of a millennial eruptive cycle on an island arc volcano (Saint Kitts, Eastern Caribbean).

TL;DR: The Mediterranean magmatic record provides an independent validation of the controversial kilometre-scale evaporative drawdown and sheds new light on the sensitivity of magmatic systems to the surface forcing.

Similarities and differences in the historical records of lava dome-building volcanoes: Implications for understanding magmatic processes and eruption forecasting
TL;DR: In this paper, the authors identify two eruptive regimes: (i) an episodic regime where eruptions are much shorter than intervening periods of repose, and degassing is temporally correlated with lava effusion; and (ii) a persistent regime where the duration of degassing and gas emissions do not correlate with eruption rates.
A Data Driven Approach to Investigate the Chemical Variability of Clinopyroxenes From the 2014–2015 Holuhraun–Bárdarbunga Eruption (Iceland)

TL;DR: In this paper, the authors investigated the chemical zoning of clinopyroxene using a data driven approach, on major and trace elements analyses from lava flow lobes emplaced during the Holuhraun-Bardarbunga eruption.
