Quench fragmentation is a non-explosive process that occurs when molten magma is super-
cooled to glass upon contact with ambient water. This occurs when coherent lavas are …

The large-scale volcanic lineaments in Iceland are an axial zone, which is delineated by the
Reykjanes, West and North Volcanic Zones (RVZ, WVZ, NVZ) and the East Volcanic Zone …

Kimberlite volcanism involves the ascent of low viscosity (0.1 to 1 Pa s) and volatile-rich
(CO2 and H2O) ultrabasic magmas from depths of 150 km or greater. Theoretical models …

The degassing of magmatic volatiles during eruptions beneath ice sheets and glaciers, as
recorded by the dissolved volatile content quenched in volcanic rocks, could provide …

The study of volcano-ice interactions, or'glaciovolcanism', is a field experiencing exponential
growth. This comprehensive volume presents a discussion of the distinctive processes and …

Landforms created in eruptions within glaciers are conspicuous features of the volcanic
zones in Iceland and eruptions occur frequently under present-day glaciers. The …

Silicic volcanic rocks within the active volcanic zones of Iceland are mainly confined to
central volcanoes. The volcanic zones of Iceland can be divided into rift zones and flank …

Helgafell, a little-eroded basaltic hyaloclastite ridge in southwest Iceland, formed in a single
eruption under a Pleistocene ice sheet. The ice thickness at the eruption site was at least …

Magma is a viscoelastic fluid that can support fracture propagation when local shear
stresses are high, or relax and flow when shear stresses are low. Here we present …

An eruption along a 2.5 km-long rhyolitic dyke at Krafla volcano, northern Iceland during the
last glacial period formed a ridge of obsidian (Hrafntinnuhryggur). The ridge rises up to 80 m …
