Gypsum and anhydrite of the Middle Carboniferous Ebbadalen and Minkinfjellet Formations were deposited in an asymmetric rift basin, the Billefjorden Trough, in Spitsbergen, Norway. The Billefjorden Fault Zone (BFZ), the western boundary of the basin, had a long polyphase history including disputed Tertiary components. It is a basement seated structure attributed to Caledonian . over the major Billefjorden lineament of central Spitsbergen (see Fig. 1 and HARLAND et al. ), extending both on to the eastern margins of the Nordfjorden block to the west, and into the Billefjorden trough to the east of this fault zone.

Billefjorden fault (Dallmann et al. ), its loca-tion close to geological units with rocks of varying degrees of resistance to erosion and weathering and the climate have led to the creation of a variety of forms in the eastern surroundings of Petunia Bukta, which according to Kostrzewski et al. () are polycyclical and polygenetic in nature. The type area is in the environs of Billefjorden in central Spitsbergen. The Billefjorden Group is a well-established lithostratigraphic unit and its overall facies development and depositional evolution is well known (e.g. Gjelberg ; Steel & Worsley ). The Ebbadalen Formation (Carboniferous) of Spitsbergen lies in an elongated basin on the downthrown side of the Billefjorden Fault Zone. Apart from the lower part of the formation, where all the beds are clastic, evaporites dominate in the basin and separate red beds, adjacent to the fault-belt, from marine carbonates. Several unconformities are recorded within the formation towards the.

The bedrock geology isdominated by dislocations along the Billefjorden Fault Zone. The longitudinally−oriented faulting has brought a wide variety of rock. In the Devonian-Carboniferous, a rapid succession of clustered extensional and contractional tectonic events is thought to have affected sedimentary rocks in central Spitsbergen, Svalbard. These events include Caledonian post-orogenic extensional collapse associated with the formation of thick Early-Middle Devonian basins, Late Devonian-Mississippian Ellesmerian contraction, and Early-Middle.

The western one is the Billefjorden Fault Zone in central-eastern Spitsbergen (e.g., 45 Harland et al., ; Manby, ; Manby et al., ; McCann and Dallmann, ; Harland. Geologically, the area is also very interesting: the Billefjorden Fault Zone, an important set of now inactive geological „cracks“, is well visible Spitsbergen book.

In the winter season, Hørbyebreen is part of the Spitsbergen book route to Dicksonfjord and Ny-Ålesund or Woodfjord, in summer it is a possible trekking route to Ålandsvatnet and Austfjord. The axial trends in the West Spitsbergen and the North Greenland Eurekan fold belts parallel the principal fault zones which accommodated the separation of Greenland and Svalbard after Chron 25/ In northern Greenland, north directed Eurekan thrusts associated with mylonites and cleavage formation represent at least 10 km of shortening.

In light of the transpres­ sional plate boundary that existed between Greenland and Spitsbergen, and the recently described Tertiary deformation along the Billefjorden Fault Zone (Haremo et al.

) it is important to learn more about the Lomfjorden Fault Complex, particularly whether it is a strike-slip, contractional or extensional fault complex.

Northwestern Spitsbergen is bounded Spitsbergen book Billefjorden and Wijde-fjorden in the east and by the coastline in the north and west round to the southwest by Kongsfjorden (Fig.

The southern boundary overlaps with Billefjorden fault zone Central Basin (Chapter 4) and central western sector of Spitsbergen (Chapter 9) along Kongsfjorden and Sveabreen. At this boundary Devonian and older rocks are uncon-formably. Actually, the Billefjorden fault zone is not only one straight fault, but rather a complex zone of a number of faults.

This is nicely visible for example north of Hørbyebreen. Spitsbergen and later united by sinistral faulting. On the other hand, and in sharp contrast to the model of Harland and co-workers, recent struct- ural mapping of rock formations adjacent to the Billefjorden Fault Zone does not tend to support large-scale lateral movements (D.

The Billefjorden Fault Zone is interpreted to extend from the shelf north of Spitsbergen to south of Isfjorden and may extend southwards into the Barents Sea. A new aeromagnetic map covering Spitsbergen and the adjacent northern Barents Sea has been compiled which shows that structures on Spitsbergen continue far into the Barents Sea.

The shear zones indicate a minimum displacement of between and km to the ENE of Zechstein and later strata over the Nordfjorden Block. Resultant folding and faulting over the Billefjorden Fault Zone represent an eastward manifestation of the Eocene West Spitsbergen Orogeny.

Billefjorden Fault Zone. Billefjorden Fault Zone (BFZ) is a long lived lineament that underwent multi-phase deformation in different tectonic regimes. BFZ is the boundary between two provinces/terrains with different thermal history and development.

Those provinces were juxtapose during Caledonian Orogeny. Seismic data in Reindalspasset also indicate that Devonian sedimentary rocks might have deposited east of the Billefjorden Fault Zone, thus ruling out Late Devonian reverse movement along the.

The consequent oblique convergence or transpression led to the development of the West Spitsbergen fold-and-thrust NW 7 km SE m Billefjorden Fault Zone. Consequently, a series of revised Late Carboniferous palaeogeographical reconstructions are presented for central Spitsbergen.
