“…Incipient rifting, most likely by oblique sinistral shear, caused the development of narrow N-S and NE-SW oriented half grabens on Spitsbergen and in the Barents Sea, respectively, during the middle Carboniferous (Harland et al, 1974(Harland et al, , 1984Gjelberg and Steel, 1981;Gjelberg, 1984Gjelberg, , 1987Stemmerik and Worsley, 1989). A thick, syn-tectonic sediment package, seismic unit K2 (Bashkirian), is observed from seismic data in the Barents Sea, especially in the Nordkapp Basin (Fig.…”

“…Note that the displaced section occurs after deposition of fluvial channels and floodplain deposits and that the delta sedimentation postdates the collapse event and fills in the space created by collapse. these units were deposited along a gently sloping shelf at the edge of the Boreal Basin, an epicontinental sea that existed in northern Pangea during the Cretaceous (e.g., Harland et al, 1984;Steel and Worsley, 1984;Torsvik et al, 2001).…”

“…The Rurikfjellet, Helvetiafjellet and Carolinefjellet formations (Fig. 2) were deposited in a large epicontinental basin that dominated the NW European margin during the Early Cretaceous, as part of the Boreal basin (Harland et al , 1984; Torsvik et al , 2001; Eide, 2002). The Boreal basin covered large areas of the present day Arctic, including portions of the Sverdrup Basin, Arctic Canada, the Alaska Basin, parts of North Greenland and the Barents Sea area (Embry, 1989; Kelly et al , 1998; Mørk & Smelror, 2001).…”

Depositional architecture of a low‐gradient ramp shelf in an epicontinental sea: the lower Cretaceous of Svalbard

Facies belts have been recorded using conventional field methods in the Lower Cretaceous Helvetiafjellet Formation in Spitsbergen, Svalbard. The formation was deposited upon a regional subaerial unconformity (SU) that developed downdip from an incised valley complex to the W, NW and possibly north of Spitsbergen during fall in relative sea level and incision into the marine Rurikfjellet Formation. The unconformity likely resulted from crustal tectonics related to the formation of the proto‐Amerasian basin. The unconformity was initially covered by braided stream facies sand and locally by small bay head delta deposits. Further rise in relative sea level resulted in transgression, and the initial braidplain turned into a low‐sloping shelf ramp of coastal plain and paralic to marine environments. Balance between increase in accommodation space and rate of sediment supply gave rise to aggradational stacking architecture of the middle and upper part of the Helvetiafjellet Formation, until further rise in sea level turned the shelf again into an open marine setting with deposition of the overlying Carolinefjellet Formation. Architectural pattern of fluvial distributary channel sandstone bodies in the aggradational succession is explained within the framework of the Boreal basin, not only the Spitsbergen outcrop domain as in previous models. The revised depositional model for the Helvetiafjellet Formation implies that fluvial systems in similar emerged epicontinental basins may have large potential to carry sand several hundreds of kilometres out into the basin with formation of fluvial sandstone intervals of large regional extent, bounded by semi‐parallel stratigraphic surfaces transecting time‐lines at very low angles. Sandstone bodies with clinoform geometry are in this setting restricted to local small‐scale paralic deltas and shoreface deposits.
