A new clinopyroxene-liquid barometer, and implications for magma storage pressures under Icelandic rift zones
DA Neave, KD Putirka - American Mineralogist, 2017 - degruyter.com
Pressure is one of the key variables that controls magmatic phase equilibria. However,
estimating magma storage pressures from erupted products can be challenging. Various …

Sector-zoned clinopyroxene as a recorder of magma history, eruption triggers, and ascent rates
Sector-zoned clinopyroxene is common in igneous rocks, but has been overlooked in the
study of magmatic processes. Whilst concentric zoning is commonly used as a record of …

Volcanic crystals as time capsules of eruption history
Crystals formed prior to a volcanic event can provide evidence of processes leading to and
timing of eruptions. Clinopyroxene is common in basaltic to intermediate volcanoes …

Mush cannibalism and disruption recorded by clinopyroxene phenocrysts at Stromboli volcano: New insights from recent 2003–2017 activity
Abstract The Present-day (< 1.2 kyr) activity of Stromboli (Aeolian Islands, Southern Italy) is
fed by a vertically-extended mush column with an open-conduit configuration. The eruptive …
