      GEOCHEMISTRY AND SIGNIFICANCE OF BASALT FLOWS. Samples taken from the three main basaltic intervals were chemically analyzed. The samples were taken from Cores A-1W, 3R, 4R, and 5R at the positions listed in Tables T1 and T2. The sample from Core A-1W is from an isolated piece of basalt (Flow 4).

Pjetursson () described two lithified "moraine" horizons separated by marine beds. Abstract. A detailed study of paleoclimatic proxy data (stable isotopes, planktonic foraminiferal census data, carbonate content, and Ice Rafted Detritus (IRD)) in the surface sediments of the Greenland, Iceland and Norwegian Seas (GIN-seas) shows that different proxies are closely related to the surface water masses, to the position of oceanic fronts and to the sea ice by: ation of the sediments at this distinctive new type of vent field and focus mainly on the hydrothermal phyllosilicates.

This long and extensive history of thin-section analysis of glacigenic sediments has given rise to a set of well-defined criteria, summarised in Table 1.

A combination of processes Recently, several researchers have argued that processes at the ice-bed interface are a result of a continuum of processes, including melt-out, lodgement.

base of the group there is an unconformity towards underlying Cretaceous units (Harland ). The unconformity is the result of a regional uplift and peripheral-bulge uplift.

In total the Van Mijenfjorden Group consists of about m of sediments which were deposited in a transgressive regressive trend (Bruhn and Steel ). The altered sediments are depleted in Mn, Rb and Sr, and enriched in U, Mo, Pb, Ba, As, Bi, Sb, Ag, Tl and Ga, as a result of leaching and precipitation, respectively.

Conservative elements (Ti, Zr, Hf, Sc, Cr, Nb and Sn) are depleted or enriched in the altered sediments because of passive (precipitation or leaching of other phases) rather than Cited by: ELSEVIER Marine Micropaleontology 35 () – Radiolarian faunal provinces in surface sediments of the Greenland, Iceland and Norwegian (GIN) Seas K.R.

Four previously known ash layers (Ash Zones I and II, Saksunarvatn and the Settlement layer) all originating in Iceland, have been identified in the Central Greenland ice core GRIP.

This correlation of the ash between the different environments is achieved by comparison of the chemical composition of glass shards from the ash. Relative sea-level (RSL) data can provide valuable constraints on land uplift associated with former ice loading and can therefore be used to differentiate between contrasting ice unloading scenarios.

The geological deformation of Iceland is the way that the rocks of the island of Iceland are changing due to tectonic forces. The geological deformation explains the location of earthquakes, volcanoes, fissures, and the shape of the island.

Iceland is the largest landmass (, km²) situated on an oceanic ridge. It is an elevated plateau of the sea floor, situated at the crossing Age: 25 million years. factors, such as bioturbation, have also influenced the BSB sediments.

(Winterhalter ) The strong variability in bedrock lithology and the distribution of deformable Quaternary sediments made the Baltic region favourable for the development of a thin and mobile ice sheet (Lambeck et.

There are indications that Tertiary and post-Tertiary volcanism in Iceland has been confined to the present main belt of active volcanism.

The geological structure of the Tertiary lava piles in the east and west of Iceland, and results of geophysical studies, may be explained by invoking an appreciable amount of crustal drift since the Cited by: where metamafic gneisses and eclogites are widespread.

Upper-amphibolite-facies metapelitic rocks, probably the Nathorst Land Group of East Greenland, were largely responsible for MN2a rutile assemblages. MN4 rutiles were mainly derived from granulite-facies metapelitic rocks, probably the Krummedal sequence of East Greenland.
