  author={John M. Sinton and Karl Gr{\"o}nvold and Kristján S{\ae}mundsson},
New field observations, age constraints, and extensive chemical analyses define the complete postglacial eruptive history of the 170‐km‐long Western Volcanic Zone (WVZ) of Iceland, the ultraslow‐spreading western boundary of the south Iceland microplate. We have identified 44 separate eruptive units, 10 of which are small‐volume eruptions associated with the flanking Grímsnes system. Overall chemical variations are consistent with very simplified models of melting of a source approximating… 

Effects of deglaciation on the petrology and eruptive history of the Western Volcanic Zone, Iceland

New observations and geochemical analyses of volcanic features in the 170-km-long Western Volcanic Zone (WVZ) of Iceland constrain spatial and temporal variations in volcanic production and

Postglacial volcanism in Iceland

Iceland is one of the most active and productive terrestrialvolcanic regions, with eruption frequency of �20 events per century and magma output rates of�5 km 3 per century. Although Iceland is

Rate of Melt Ascent Beneath Iceland From the Magmatic Response to Deglaciation

Observations of the time lag between the last deglaciation and a surge in volcanic activity in Iceland constrain the average melt ascent velocity to be ≥50 m/year. Although existing theoretical work

Feedback between deglaciation and volcanic emissions of CO 2

The concentration of atmospheric CO2 has varied in near lock-step with glaciation over the course of at least the late Pleistocene. These glacial/interglacial variations in CO2 are generally

Pressures of Crystallization of Icelandic Magmas

Iceland lies astride the Mid-Atlantic Ridge and was created by seafloor spreading that began about 55 Ma. The crust is anomalously thick (� 20^40 km), indicating higher melt productivity in the

Intraglacial volcanism in the Western Volcanic Zone, Iceland

The Western Volcanic Zone in Iceland (64.19° to 65.22° N) has the morphological characteristics of a distinct Mid-Atlantic ridge segment. This volcanic zone was mapped at a scale of 1:36.000, and 258

Postglacial eruptive history of the Askja region, North Iceland

Temporal variations in magma discharge rates on Iceland’s neovolcanic rift zones have been associated with deglaciation. We have used tephrochronological and stratigraphic dating of 175 separate

Geochemical evolution of basaltic tuyas in Iceland during the last deglaciation

Tuyas are subglacial volcanoes that preserve a unique history of the interplay between glaciation and hot spot volcanism in Iceland during the last deglaciation. Geochemical signatures in eruptive



The link between volcanism and deglaciation in Iceland

Temporal variation in the eruption rate and lava composition in the rift zones of Iceland is associated with deglaciation. Average eruption rates after the end of the last glacial period, ∼12 kyr BP,

Petrological and geochemical variations along Iceland's Neovolcanic Zones

Petrological, geochemical, and geophysical gradients along the SE volcanic zone in Iceland imply systematic variations in melting and crystallization conditions and in magma supply and eruption

Iceland geochemical anomaly: Origin, volcanotectonics, chemical fractionation and isotope evolution of the crust

Iceland is an oceanic plateau produced by channeled flow from the Iceland hotspot. The Icelandic rift system moves WNW relative to the hotspot. About magnetic anomaly 7 time the rift system overrode

Volcanic History and Tectonics of the North Langjökull Region, Central Iceland

The geology of the area around the northern part of the Langjokull ice sheet in central Iceland is outlined. This area includes the termination of the western neovolcanic zone, two silicic centers,

Effect of glacier loading/deloading on volcanism: postglacial volcanic production rate of the Dyngjufjöll area, central Iceland

Tephrochronological dating of postglacial volcanism in the Dyngjufjöll volcanic complex, a major spreading center in the Icelandic Rift Zone, indicates a high production rate in the millennia

The effect of deglaciation on mantle melting beneath Iceland

The spreading ridge on Iceland shows large variations in eruption rate over the last 10,000 years. An increase of about 30 times the steady state value, between 10,000 and 8000 years ago, coincides
