Abstract Lithofacies characteristics and depositional geometry of a sandy, prograding delta deposited as part the Holocene valley‐fill stratigraphy in Målselv valley, northern Norway, were examined using morpho‐sedimentary mapping, facies analysis sediments exposed sections, auger drilling ground penetrating radar survey. Various lithofacies types record broad range processes within an overall coarsening‐upward succession comprising lowermost prodelta/bottomset unit, intermediate...

The basal erosion rate and sediment yield of the Vestfjorden paleo–ice stream, a marine-based part northwestern Fennoscandian Ice Sheet, were elucidated during complete advance-retreat cycle using high-resolution seismic data multi-beam bathymetry. In most area, there is semitransparent, continuous upper unit showing southwestward (down-fjord) progradational pattern with megascale glacial lineations on top, interpreted to represent subglacial deformable till. till formed bed beneath except...

Abstract The sediment fill of a silled bedrock valley in Western Norway has been investigated with respect to stratigraphy and infill history using combination mapping, georadar, seismic profiling drilling. A small outlet glacier occupies the head that displays stepwise down‐valley profile terminates lake at 29 m above sea‐level. is surrounded by high, steep slopes characterized series filled basins each limited sills or moraine accumulations. Till, glacial outwash and/or rockslide deposits...

Abstract The glacial history in the topographically confined paleo-ice stream drainage route of Vestfjorden, North Norway, was analysed based on bathymetric data, high-resolution seismology and 14 C AMS-dated gravity cores. inner part fjord is characterised by axial-parallel mega-scale lineations whereas outer dominated two marginal morainal bank systems. Værøy (inner) Røst (outer) moraine systems comprise several transverse, zigzag-shaped ridges. Seismic records show thrusted folded...

The deglaciation history of the Malangen‐Målselv fjord and valley area proximally to Tromsø‐Lyngen (Younger Dryas) moraine at Bakkejord, Malangen, northern Norway, is reconstructed based on morphostratigraphic, lithostratigraphic geophysical evidence, 25 radiocarbon dates from marine shells foraminifera. results show that following Skarpnes event c . 12 200 14 Cyr BP, prior Younger Dryas readvance, was deglaciated least as far Sandmo situated 22 km moraine. Two ridges crossing buried beneath...

Few well‐dated records of the deglacial dynamics large palaeo‐ice streams major Northern Hemisphere ice sheets are presently available, a prerequisite for an improved understanding ice‐sheet response to climate warming this period. Here we present transect gravity‐core samples through Trænadjupet and Vestfjorden, northern Norway, location – Vestfjorden stream NW sector Fennoscandian Ice Sheet. Initial recession from shelf break coastal area (~400 km) occurred at average rate about 195 m −1 ,...

High-resolution bathymetrical data from the Lovatnet lake, western Norway, reveal a diverse morphology including traces historic and prehistoric landslides. Onshore LiDAR selected seismic profiles support interpretation. Our lake show significant debris lobes below Ramnefjellet that was source of well-known rock avalanche tsunami disasters in 1905 1936 which caused total 134 casualties. The is divided into three main reaching length 1.8 km along bottom impact site, diffuse lobe features...

Depositional terraces of diverse origin are common in Norwegian fjord valleys. They differ subtly morphologically and may be difficult to distinguish from one another without detailed field stratigraphic investigation. We used LiDAR elevational data describe previously identified glaciofluvial, glaciodeltaic, fluvial, fluviodeltaic the Målselv valley, northern Norway, show how they morphologically. Fluvial divided into two subtypes based on their difference morphology. One type shows an...

Overdeepened valleys and troughs on the northern southern margins of central European Alps have been shaped during Quaternary glaciations (Preusser et al. 2010).These host a number fjord-type lakes, remnants formerly larger water bodies, which show various morphological features that reflect their glacial origin, similar to marine fjords.Among most prominent these are large-scale transverse moraine ridges in Lake Lucerne, perialpine lake situated branched valley system margin (Fig. 1b,c).

Hummocky terrain in deglaciated areas is often attributed to ‘dead-ice’ activity, that is, a depositional environment produced by the presence and melt-out of large blocks stagnant ice (Gravenor & Kupsch 1959; Eyles et al. 1999). Morphologically similar dead-ice found on floor Lake Bandak southern Norway, former fjord now isolated from sea, where glacier terminated during Late Weichselian deglaciation. Lake an east–west-orientated lake with length c. 26 km, average width 1 area 26.4 km2...

The eastern slope of Garmaksla, a flat-topped mountain at the western margin Billefjorden, Svalbard, is affected by mass movements different types. Rotational rock slides, fall and avalanche affecting coastal cliff are shallow surface expressions covering larger instability that bordered to west Balliolbreen Fault. This structural feature part Billefjorden Fault Zone accommodated multi-phase deformation since Devonian time. Based on comprehensive morpho-structural analysis, mapped features...

The fjords and valleys of Norway have been shaped during several glacial cycles the Quaternary period. Subaquatic ridges that formed at or close to grounding lines glacier termini stillstands readvances within last deglaciation are commonly found fjords. An example is a prominent moraine ridge representing readvance Fennoscandian Ice Sheet Younger Dryas ( c. 12.9–11.5 ka BP) in Norddalsfjorden, More og Romsdal, Norway. Fjord deltas may form same setting mouths tributary fjord heads following...

Abstract We here describe the results of stratigraphic and sedimentological examinations debris flow deposits at Breidokk, Gol, southern Norway. The are situated valley floor, below a steep slope with three large several smaller channels incised into thick till cover. study area is populated abundant infrastructure such as roads, public private buildings other types infrastructure, including underground water pipes cables. Six, 10–15 m long 1–3 deep trenches were dug out an excavator...
