Magma mixing induced by particle settling. [PDF]
Contrib Mineral Petrol, 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

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.

Analogue experiments to investigate magma mixing within dykes. [PDF]
Bull VolcanolAbstract 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.

Experiments on magma mixing [PDF]
Geophysical Research Letters, 2004 The arrival of a new hot batch of magma changes the thermal and the chemical state of a volcanic plumbing system. Formation of hybrid magma by chemical dilution (liquid miscibility model) of different magma batches is generally accepted. Observations of drop‐like domains of less evolved (newer) magma in more evolved (host) magma point to the ...

Concentration variance decay during magma mixing: a volcanic chronometer. [PDF]
Sci Rep, 2015 AbstractThe mixing of magmas is a common phenomenon in explosive eruptions. Concentration variance is a useful metric of this process and its decay (CVD) with time is an inevitable consequence during the progress of magma mixing. In order to calibrate this petrological/volcanological clock we have performed a time-series of high temperature experiments

Dynamics of Magma Mixing in Partially Crystallized Magma Chambers: Textural and Petrological Constraints from the Basal Complex of the Austurhorn Intrusion (SE Iceland) [PDF]
, 2017 The Tertiary Austurhorn intrusive complex in SE Iceland represents an exhumed magma chamber that has recorded an extensive history of magma mixing and mingling.

Onset of solid-state mantle convection and mixing during magma ocean solidification [PDF]
, 2016 ©2017. American Geophysical UnionThe energy sources involved in the early stages of the formation of terrestrial bodies can induce partial or even complete melting of the mantle, leading to the emergence of magma oceans. The fractional crystallization of
