Abstract: The little explored Cambodian and Vietnamese Phuquoc–Kampot Som Basin is a Late Jurassic to Early Cretaceous foreland basin developed in response the build-up of palaeo-Pacific magmatic arc. A combination seismic data, well data outcrop geology complemented by fission track U/Pb analysis used unravel history. This reveals hitherto unknown earliest Palaeogene inversion associated with Luconian suturing SE Asia shutdown subduction underneath Asia. Khorat Thailand constitute erosional...
Glaciotectonic studies are an integrated part of the Quaternary geological research carried out by Danish survey. Almost all hilly areas in Denmark were created or affected glaciotectonic deformations, and features included mapping surface near deposits. For support constructing 3D models a classification architecture complexes is suggested. The important elements for surfaces. Four orders surfaces defined complexes: first-order décollement unconformities; second-order ramps flats—the thrust...
Pedersen, S.A.S. 2005: Structural analysis of the Rubjerg Knude Glaciotectonic Complex, Vendsyssel, northern Denmark. Geological Survey Denmark and Greenland Bulletin 8, 192 pp.
 The Complex is a thin-skinned thrust-fault complex that was formed during advance Scandinavian Ice Sheet (30 000 – 26 B.P.); it well exposed in 6 km long coastal profile bordering North Sea glaciotectonic deformation revealed by this cliff section has been subjected to detailed structural based on...
The Early Eocene Fur Formation is a clayey diatomite interbedded with layers of volcanic ash. non-calcareous, laminated or structureless, and thin sections show that the proportion clay-sized particles to diatom frustules varies between laminae. clay mineral phase has been isolated its chemical composition determined by X-ray fluorescence (XRF). Clay mineralogical analyses based on diffraction (XRD) dominant smectite. A general formula for is:...
Summary Two different modes of gravity tectonics have been active as deformation mechanisms in the Quaternary Denmark, namely ‘gravity gliding’ and spreading’. Examples gliding can be found fairly slowly moving coherent landslides which characterize many coastal cliffs with lithologies intercalated Tertiary marine clay or interglacial clay. The spreading mechanism generated folds dislocation structures characteristic glacial tectonics, mainly during Weichselian glacier advances Pleistocene...
Compared to many areas of the world, human losses caused by natural hazards are smaller in Nordic countries.This is mainly due low population density exposed areas.However, economic significant and geohazards picture varies among countries.The predominant countries floods, landslides, and, with exception Denmark, snow avalanche.Volcanoes earthquakes major Iceland, parts Norway susceptible seismic activity.
Abstract The glaciofluvial deposits are by volume and permeability the most important unit in terrestrial glacial successions, they obvious target for groundwater as well hydrocarbon reservoir exploration. dominant units related to proglacial setting foreland of an advancing ice margin, which results a coarsening-upwards sequence with fine-grained beds at base gravel top. In complete till caps unit, its glacitectonite is formed shearing development deformational layer below ice. laid down...
Abstract Latest Mesozoic to earliest Cenozoic deformation affected SE Asia's Sundaland core. The event bridges the Asian fusion with era of rifting, translation, basin formation, and creation modern oceans. Southern Cambodia Vietnam are central this shift, but geological investigations region in their infancy. Based on apatite zircon fission track analyses (AFTA ZFTA), stratigraphic structural observations, seismic data, thermal maturity, igneous rock dating, evolution southern is...
The identification of glaciotectonic structures is an exclusive field for the structural geologist. comprise a series different types and regimes. sequential development reflects superimposed subglacial proglacial deformation processes. may involve earlier formed thus by glaciotectonics, or eventually be overprinted neotectonic deformations. Four settings distinguished: 1) on pre-Quaternary tectonics, 2) (superimposed involving two more glaciodynamic events), 3) deformations sequentially in...
The preliminary results of a reconnaissance survey the coast between Kangerdlugssuaq and Angmagssalik are summarized. Archaean gneiss complex Kap Japetus Steenstrup is fairly uniform comprises granitoid gneisses with inclusions supracrustal rocks, layered basic igneous complexes older gneisses. Inland areas generally show low deformation states, large scale recumbent folds, rocks in granulite facies, whereas belt stronger deformation, steep foliation amphibolite facies matamorphism extends...
The historical ‘de Geer Line’ between Svalbard and Greenland is shown to have had a Mesozoic precursor now residing well within the continental plate, where it coincides with Wandel Hav Strike-Slip Mobile Belt. Well-constrained phases in relative plate motion reflected mobile belt are discernible back mid Jurassic, more obscure dating even further back. There evidence that Belt may been formed already Late Palaeozoic time during onset of Pangean break-up; for strike-slip movements this age...
During the afternoon of 21 November 2000 village Saqqaq in central West Greenland was hit by a series giant waves. Ten small boats were destroyed, but luckily neither humans nor dogs killed. The following day police inspection helicopter revealed that waves caused major landslide at Paatuut, c. 40 km north-west on south coast Nuussuaq (Figs 1, 2). deposits dark grey-brown colour, marked contrast to snow-covered slopes, and protruded as lobe into Vaigat strait. Along adjacent coastlines snow...
Granitoid rocks from different settings within the northern part of East Greenland Caledonian fold belt have yielded U–Pb zircon dates between 2000 and 1730 Ma, confirming Palaeoproterozoic origin crystalline basement. Widespread sandstone sequences occur both in foreland to west; all these been assigned Independence Fjord Group, attributed a Mesoproterozoic age on geological maps. However, metarhyolitic associated with sandstones an 1740 ± 6 significantly older than anticipated. Zircon ages...
Abstract In the North Atlantic, Laurentia–Eurasia break-up commenced in Late Carboniferous, largely following structural grain of Caledonian Fold Belt. However, Arctic region, a 45° offset plate boundary between Greenland and Svalbard was determined by number pre-Caledonian fundamental faults Greenland. As result, this segment experienced significant episodes combined transtension transpression, part controlled movement temporarily independent Plate. Permian–Mesozoic deposits Wandel Sea...
Sedimentological analysis of the Weichselian deposits exposed in coastal cliff section at Lønstrup Klint, northern Jutland, Denmark, demonstrates presence four sedimentary units comprising fine‐grained lacustrine and fluvial latest Middle Wcichselian. The Klint also shows an interplay between glaciotectonics sedimentation. two lower are separated by erosional unconformity pretectonic origin, whereas upper syntectonic. glaciotectonic processes reflect Late expansion Scandinavian ice cap into...

The Møns Klint Glaciotectonic Complex (Fig. 1) exposed in the N–S-trending chalk cliff on east coast of island Møn south-east Denmark is one most famous glaciotectonic geosites world. People all nationalities are attracted to site, which has more than 300 000 visitors per year. Many them may not realise uniqueness framework, and probably fascinated by spectacular view white peaks separated deep green gorges. However, without deformation cliffs would never have formed. Instead Cretaceous...
