Analogue experiments to investigate magma mixing within dykes [PDF]
Bulletin of VolcanologyAbstract Multiple magmas residing in plumbing systems that feed fissure eruptions can physically and chemically interact and mix during storage, transport, and eruption. The extent and success of such mixing ultimately control the physical properties (e.g.

Magma mixing induced by particle settling [PDF]
Contributions to Mineralogy and Petrology, 2016 A time series of experiments at high temperature have been performed to investigate the influence of particle settling on magma mixing. A natural rhyolite glass was held above a natural basalt glass in a platinum crucible. After melting of the glasses at superliquidus temperatures, a platinum sphere was placed on the upper surface of the rhyolitic melt

Magma Mixing: History and Dynamics of an Eruption Trigger [PDF]
, 2017 The most violent and catastrophic volcanic eruptions on Earth have been triggered by the refilling of a felsic volcanic magma chamber by a hotter more mafic magma. Examples include Vesuvius 79 AD, Krakatau 1883, Pinatubo 1991, and Eyjafjallajokull 2010.

Numerical simulation of convection and mixing in magma chambers replenished with CO2‐rich magma
Geophysical Research Letters, 2006 Magma convection and mixing, and periodic refilling, commonly occur in magma chambers. We show here that the presence of CO2 in the refilling magma is a very efficient mean of inducing buoyant‐driven plume rise and large scale convection. Numerical simulations performed with an appositely developed code for the transient 2D dynamics of multicomponent ...

The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Mafic-silicic magma interaction in the layered 1.87 Ga Soukkio Complex in Mäntsälä, southern Finland [PDF]
Bulletin of the Geological Society of Finland, 2002 The Svecofennian layered Soukkio Complex (1.87 Ga) in Mäntsälä, southern Finland, consists of layered tholeiitic gabbro and porphyritic calc-alkaline monzonite, quartz monzonite and granite, mingled together.
