“…They are characterised by crinoid, bryozoan and brachiopodrich limestones deposited in inner-shelf environments. However, in the Sverdrup Basin, elements of the subtropical biota such as fusulinids and colonial corals are present in the shallowest near-shore microfacies (Larssen et al, 2002;Reid et al, 2007). In this locality, evidence of subaerial exposure at the top of the Great Bear Cape Formation and succeeding deltaic deposits of the Sabine Bay Formation might relate to compressional tectonic events during the Kungurian-Melvillian.…”

“…In this locality, evidence of subaerial exposure at the top of the Great Bear Cape Formation and succeeding deltaic deposits of the Sabine Bay Formation might relate to compressional tectonic events during the Kungurian-Melvillian. This tectonic activity caused uplift of the Sverdrup basin margins (Reid et al, 2007). During the remainder of Permian time, the Sverdrup Basin records the onset of passive subsidence, except for a localised uplift of the Tanquary High in the northeast (Reid et al, 2007;Bensing et al, 2008).…”

“…In the fine-grained, mixed-bioclastic limestones (MFT-9), extensive bioturbation (mainly by Skolithos and Zoophycos trace fossils) and occasional glauconite minerals indicate low sedimentation rates and suggest breaks in the storm activity. Reid et al (2007) and Blomeier et al (2013) interpreted the occurrence of trace fossils in the upper part of storm deposits as the increased activity of opportunistic sediment feeders in the aftermath of a storm.…”

“…Additionally, the closure of the Uralian seaway during the Kungurian caused the cutoff of the supply of warm waters of the Tethys (Blomeier et al, 2011). Changes in oceanic circulation patterns accompanied by local palaeogeographical changes during the northward movement of Pangea hence resulted in the decrease of the water temperature from warm to temperate and cold marine conditions along the western and northern margin of Pangea (Beauchamp, 1994;Stemmerik & Worsley, 1995;Reid et al, 2007;Beauchamp & Grasby, 2012).…”

Because of outstanding outcrops, Spitsbergen (Svalbard archipelago) provides unique opportunities to investigate the whole Upper Palaeozoic succession in great detail. This study can help to interpret the stratigraphic history and depositional evolution at other locations exposing coeval shelf strata along the northern margin of Pangea, e.g., the southern Barents Sea and Arctic Canada. Bed-scale outcrop observations are combined with microfacies studies to interpret the sedimentary settings and depositional environment of the Upper Palaeozoic strata. A sequencestratigraphic analysis has been carried out to evaluate the relative timing of sediment facies deposition in response to sea-level changes. The Early Artinskian to Kazanian successions of the Templet Member and the Kapp Starostin Formation were divided into five parasequences that are superimposed on a long-term, second-order, sea-level fall. These parasequences record a fundamental change of the sedimentary setting, from a restricted-marine, warm-water carbonate platform to an open-marine, cold-water, biosiliceous-carbonate ramp system. A cross-section across Svalbard comprising nine onshore sections shows that during deposition of the Kapp Starostin Formation a major depocentre marked by thick parasequences and a higher proportion of deep-water facies (bedded cherts) is located in the southwest of Spitsbergen (at Akseløya), whereas northeastern Svalbard records shallow-water microfacies. Svalbard was tectonically passive during the Permian; the local differences in accommodation space and facies were most likely linked to the rejuvenation of pre-existing structural elements, inherited from the Carboniferous. A deepening of the depositional environment combined with cold-water climatic conditions as recorded in our study area has also been documented in other Upper Palaeozoic successions around the Arctic, such as the Finnmark Platform (Norwegian Barents Sea) and the Sverdrup Basin (Arctic Canada). This transition in the depositional environment along the northern margin of Pangea is the result of large-scale changes in oceanic circulation patterns and local palaeogeographic changes during the northward movement of Pangea.

A detailed facies study of Early Permian strata within NE Svalbard reveals a fundamental change of the depositional setting, from a restricted-marine, warm-water carbonate platform to an open-marine, temperate-water, mixed siliciclastic-carbonate ramp. The uppermost strata of the Gipshuken Formation (Templet and Sørfonna members; Sakmarian-early Artinskian?) consist of microbialites (algal mats), mudstones, bioclastic/peloidal limestones, carbonate breccias and Microcodium facies reflecting peritidal platform areas and supratidal sabkhas. A mixed heterozoan/reduced photozoan assemblage indicates temperate-water conditions within neighboring deeper, openmarine mid-platform areas, while warm-water conditions still prevailed within inner platform zones. In contrast, the lowermost strata of the overlying Kapp Starostin Formation (Vøringen Member; late Artinskian?-Kungurian) show a fully heterozoan biotic assemblage reflecting temperate water conditions within open-marine, storm-dominated, nearshore to transitional offshore areas of a mixed carbonatesiliciclastic ramp. The Vøringen Member comprises three facies associations, which form a shallowing-upward sequence subsequent to an initial transgression. The sediments reflect bryozoan bioherms in most distal areas, followed by stacked tempestites of sandy brachiopodal shell banks and Skolithos piperocks, grading into broad sand flats in most proximal areas of the inner ramp. The above environmental change is regarded as a regional event taken place across the entire shelf along the northern margin of Pangea and is attributed to paleoclimatic, paleoceanographic, as well as paleogeographic changes, possibly related to the overall northwards drift of the supercontinent. An abrupt increase in terrigenous input coinciding with this change is ascribed to the uplift of a new local source area, probably to the north or east of the investigation area.
