Pauzhetka Caldera (South Kamchatka): Еxploring Temporal Evolution and Origin of Voluminous Silicic Magmatism
The Pauzhetka Caldera (27 × 18 km) was formed in the South Kamchatka during the Golygin Ignimbrite eruption (420–440 ka), the largest known eruption...

Multi-method constraints on the age and timescale of silicic small-volume eruptions of Puketerata Volcanic Complex, Taupō Volcanic Zone, New Zealand
Accurate dating of young eruptions from explosive volcanoes is essential for forecasting future eruptions and for defining the hazardscape of...

Dynamics and timescales of mafic–silicic magma interactions at Soufrière Hills Volcano, Montserrat
Mafic magma intrusions into silica-rich magmatic reservoirs are commonly proposed to drive the eruptions of andesitic hybrid magmas that characterise...

Do arc silicic magmas form by fluid-fluxed melting of older arc crust or fractionation of basaltic magmas?
Under the right circumstances, fluid-fluxed crustal melting occurs, as demonstrated by some amphibolite-facies migmatites, but the relatively low...

Temporal variations in the diversity of primitive melts supplied to the Santorini silicic magmatic system and links to lithospheric stresses
The South Aegean Volcanic Arc overlies a slowly subducting, cool slab of oceanic-to-transitional crust, and hosts the hazardous...

Residual Melt after the Crystallization of Oxide Gabbro: An Example of a Silicic Product of MORB Differentiation in the Modern Oceanic Crust, Ashadze Complex, Central Atlantic
AbstractThe plutonic rocks studied in the Ashadze Complex contain four groups of mineral assemblages: (I) coarse-grained gabbronorite, which is...

Melt inclusions in zircon: a window to understanding the structure and evolution of the magmatic system beneath the Laguna del Maule volcanic field
Explosive silicic eruptions pose a significant threat to society, yet the development and destabilization of the underlying silicic magmatic systems...

The evolution of diamond-forming fluids indicating a pre-kimberlitic metasomatic event in the mantle beneath the Mirny field (Siberian craton)
A suite of coated diamonds from the International’naya ( n = 63) and Mir ( n = 5) kimberlite pipes (Mirny field, Siberian craton) was studied to track...

Timescales and thermal evolution of large silicic magma reservoirs during an ignimbrite flare-up: perspectives from zircon
Four voluminous ignimbrites (150–500 km 3 ) erupted in rapid succession at 27 Ma in the central San Juan caldera cluster, Colorado. To reconstruct the...

Formation of ferroan dacite by lunar silicic volcanism recorded in a meteorite from the Moon
An igneous clast from the Northwest Africa 773 (NWA 773) clan of lunar meteorites formed by silicic volcanism on the Moon. The clast was identified...
