AN EXPLORATORY METHOD TO DETECT TEPHRAS FROM QUANTITATIVE XRD SCANS: EXAMPLES FROM ICELAND AND EAST GREENLAND MARINE SEDIMENTS

Andrews J.T.; Eberl D.D.; Kristjansdottir G.B. (2006)

Tephras, mainly from Iceland, are becoming increasingly important in interpreting leads and lags in the Holocene climate system across NW Europe. Here we demonstrate that Quantitative Phase Analysis of x-ray diffractograms ...
APPLICATION OF 2D HYDRODYNAMIC MODELLING TO HIGH-MAGNITUDE OUTBURST FLOODS: AN EXAMPLE FROM KVERKFJöLL, ICELAND

Carrivick J.L. (2006)

High-magnitude outburst floods cause rapid landscape change and are a hazard to life, property and infrastructure. However, high-magnitude fluvial processes and mechanisms of erosion, transport and deposition are very ...
CONSTRAINTS ON THE DYNAMICS OF SUBGLACIAL BASALT ERUPTIONS FROM GEOLOGICAL AND GEOCHEMICAL OBSERVATIONS AT KVERKFJöLL, NE-ICELAND

Höskuldsson A.; Sparks R.S.J.; Carroll M.R. (2006)

The Kverkfjöll area, NE Iceland is characterised by subglacial basalt pillow lavas erupted under thick ice during the last major glaciation in Iceland. The water contents of slightly vesiculated glassy rims of pillows in ...
CRUST-PRIMITIVE MAGMA INTERACTION BENEATH NEOVOLCANIC RIFT ZONE OF ICELAND RECORDED IN GABBRO XENOLITHS FROM MIDFELL, SW ICELAND

Gurenko A.A.; Sobolev A.V. (2006)

We studied glass-bearing gabbro xenoliths from picritic pillow lavas erupted in the Midfell area, SW Iceland. The aim of this study is to investigate the processes affecting chemical composition of primitive Icelandic ...
EVIDENCE FROM P-TO-S MANTLE CONVERTED WAVES FOR A FLAT "660-KM" DISCONTINUITY BENEATH ICELAND

Du Z.; Vinnik L.P.; Foulger G.R. (2006)

Iceland is the type example of a ridge-centered hotspot. It is controversial whether the seismic anomaly beneath it originates in the lower mantle or the upper mantle. Some recent studies reported that the 660-km discontinuity ...
FIRST RESULTS FROM THE NORTH ICELAND EXPERIMENT

Riedel C.; Tryggvason A.; Brandsdottír B.; Dahm T.; Stéfansson R.; Hensch M.; Böðvarsson R.; Vogfjord K.S.; Jakobsdottír S.; Eken T.; Herber R.; Holmjarn J.; Schnese M.; Thölen M.; Hofmann B.; Sigurdsson B.; Winter S. (2006)

Between June 2004 and September 2004 a temporary seismic network was installed on the northern insular shelf of Iceland and onshore in north Iceland. The seismic setup aimed at resolving the subsurface structure and, thus, ...
ON THE USE OF TELESEISMIC RECEIVER FUNCTIONS FOR STUDYING THE CRUSTAL STRUCTURE OF ICELAND

Schlindwein V. (2006)

The character of the crust-mantle transition beneath Iceland, a ridge-centred hotspot, is not well known despite a wealth of geophysical data including recent seismic refraction profiles. scattered observations of a ...
RADIOCARBON DATING OF MID-HOLOCENE MEGAFLOOD DEPOSITS IN THE JOKULSA A FJOLLUM, NORTH ICELAND

Kirkbride M.P.; Dugmore A.J.; Brazier V. (2006)

Two megafloods in the canyon of the Jokulsi i FjOllum, the major northern routeway for glaciovolcanic floods from VatnajOkull, have been closely dated by 14C AMS dates from Betula macrofossils within peat immediately below ...
RAPID SEA-LEVEL RISE IN THE NORTH ATLANTIC OCEAN SINCE THE FIRST HALF OF THE NINETEENTH CENTURY

Gehrels W.R.; Marshall W.A.; Gehrels M.J.; Larsen G.; Eiríksson J.; Kirby J.R.; Heinemeier J.; Shimmield T. (2006)

A high-resolution late-Holocene sea-level record is produced from salt-marsh deposits at Vioarhólmi in Snæfellsnes, western Iceland. The stratigraphy of Vioarhólmi saltmarsh is documented using detailed descriptions of ten ...
TEMPORAL DEVELOPMENT OF THE 1999 INTRUSIVE EPISODE IN THE EYJAFJALLAJöKULL VOLCANO, ICELAND, DERIVED FROM INSAR IMAGES

Pedersen R.; Sigmundsson F. (2006)

Eyjafjallajökull volcano, located in southern Iceland, is characterized by its quiet nature. Only about a handful of earthquakes associated with the volcanic system had been detected prior to the 1990s. Earthquake swarms ...
