Pyroclastic density currents: state of the art and perspectives

R Sulpizio, P Dellino, DM Doronzo… - Journal of Volcanology and …, 2014‏ - Elsevier
Pyroclastic density currents (PDCs) are mixtures of two components, namely solid particles
and fluid (gas) phase. They macroscopically behave as dense, multiphase gravity currents …

Quantum magmatism: Magmatic compositional gaps generated by melt-crystal dynamics

J Dufek, O Bachmann - Geology, 2010‏ - pubs.geoscienceworld.org
Compositional gaps are common in volcanic series worldwide. The pervasive generation of
compositional gaps influences the mechanical and thermal properties of the crust, and holds …

Trace element indicators of crystal accumulation in silicic igneous rocks

CD Deering, O Bachmann - Earth and Planetary Science Letters, 2010‏ - Elsevier
If fractional crystallization coupled with some crustal assimilation (AFC) is the dominant
process for generating evolved magmas in the Earth's crust, large quantities of igneous …

The fluid mechanics of pyroclastic density currents

J Dufek - Annual Review of Fluid Mechanics, 2016‏ - annualreviews.org
Pyroclastic density currents are generated in explosive volcanic eruptions when gas and
particle mixtures remain denser than the surrounding atmosphere. These mobile currents …

Homogenization processes in silicic magma chambers by stirring and mushification (latent heat buffering)

C Huber, O Bachmann, M Manga - Earth and Planetary Science Letters, 2009‏ - Elsevier
Heterogeneities in crustal magma chambers are generated by incomplete mixing of different
batches of magmas, precipitation or remelting of solids~ 10–20% denser than surrounding …

On the kinematics and dynamics of crystal‐rich systems

GW Bergantz, JM Schleicher… - Journal of Geophysical …, 2017‏ - Wiley Online Library
Partially molten rocks, often called a mush, are examples of a hydrogranular mixture where
the dynamics are controlled by both fluid and crystal‐crystal interactions. An obstacle to …

Rift-related transition from andesite to rhyolite volcanism in the Taupo Volcanic Zone (New Zealand) controlled by crystal–melt dynamics in mush zones with variable …
