Thick crust, hydrous magmas, and the paradox of voluminous cold magmatism
Volcanica, 2021 Andesites are refined and “cold” magmas compared to their basaltic parents, yet large volumes of andesites are generated at continental arcs. We show that large andesitic plutons are favored when arc crust attains a thickness of ~60 km while mafic ...

Energy Science &Engineering, EarlyView.The novelty of the current study is that the unsteady MHD Cross nanofluid model is, for the first time, coupled with the melting heat transfer at the stagnation point over a horizontally extended cylinder in a Darcy–Forchheimer porous medium. This work connects complex rheological behaviors and phase‐change phenomena in a unique way, with the only ...

NATO i Zapadni Balkan u uvjetima novih sigurnosnih izazova
Međunarodne Studije, 2014 U skladu sa zaključcima donesenim na NATO-ovom samitu u Walesu, posebno s onim kako će NATO ostati „temeljem naše kolektivne obrane“, zemlje Zapadnog Balkana svjesne su važnosti pripadanja transatlantskom sigurnosnom okruženju, vođenom od strane NATO-a ...

On the mechanism of interaction between strong earthquakes and volcanism in subduction zones
Вестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2022 The relationship between strong earthquakes and powerful volcanism in subduction zones are discussed. It is shown that abnormally strong earthquakes or a group of strong earthquakes and powerful volcanic events or volcanic activation of large areas can ...

Geological Journal, EarlyView.Coupled dissolution‐reprecipitation of early formed Cd‐, Fe‐, Ag‐ and Sb‐poor sphalerite through interaction with high‐temperature and high‐sulphur fugacity Cu‐rich fluids, responsible for the formation of the yellow ores, resulted in the formation of Cd‐, Fe‐, Ag‐ and Sb‐rich, heavily chalcopyrite‐diseased sphalerite and enrichment of critical metals ...

Understanding silicic volcanism: Constraints from elasticity and failure of vesicular magma [PDF]
, 2005 Volcanic eruptions are one of the most spectacular and dangerous natural phenomena. Volcanic activity can either be effusive, dominated by quiescent emission of lava or explosive, dominated by the eruption of pyroclastic material.

Magma mobilization by downward-propagating decompression of the Eyjafjallajökull volcanic plumbing system [PDF]
Detailed observations of the 2010 Eyjafjallajökull eruptions in Iceland show seismic activity propagating vertically through the entire crust during a ten-week period of volcanic unrest comprising multiple eruption episodes.

Geological Journal, EarlyView.The composition of intrusive rocks suggests that the magma was likely generated in a subduction‐related setting. The arc crustal thickness in the Phnom Sro Ngam and Halo Prospects was probably < 40 km during emplacement. Zircon U–Pb age range indicates a correlation with Loei Fold Belt magmatic activity.
