Climate variations in the Boreal Triassic — Inferred from palynological records from the Barents Sea

Regional development and sequence stratigraphy of the Middle to Late Triassic Snadd Formation, Norwegian Barents Sea

“…13). In the uppermost part of the C4 sequence, the thin coal beds and carbonaceous shale and silt are abundant in these sequence, both in outcrop and in well logs, reflecting the reported change in climatic conditions (Hochuli and Vigran, 2010). Interestingly, nodular carbonate beds are reported from outcrop in central Spitsbergen and on Hopen.…”

“…Although the climate is reported to be more arid in the Early Carnian (Hochuli and Vigran, 2010), coal fragments are common in most of the channel deposits from this period and core from well 7131/4-1 also indicate vegetated and water logged soil profiles at the base of Early Carnian channel sands. Local to regional climate variations might have existed along the coastal areas during the overall arid Early Carnian, and monsoonal are reported on southern latitudes (Mutti and Weissert, 1995).…”

“…When the formation was deposited, paleolatitudes were 50 to 55 for the Svalbard archipelago (Golonka, 2007;Worsley, 2008;Ziegler, 1988), with the Barents Sea thus located at about 44 to 49 accordingly. The study area experienced a change from arid to humid climate in the Carnian (Hochuli and Vigran, 2010). extrapolating to 2D-seismic data and for interpretation of well logs.…”

Climate variability during the Carnian Pluvial Phase — A quantitative palynological study of the Carnian sedimentary succession at Lunz am See, Northern Calcareous Alps, Austria

“…Our studied lower interval of the Opponitz Formation belongs in agreement with Roghi et al (2010) to their L. martinii assemblage. Hochuli and Vigran (2010) and Vigran et al (2014) describe intervals with similar palynomorph assemblages from the Barents Sea and the Svalbard Archipelago. However, our data (Mueller et al, under review) suggests that similar palynomorph assemblages are of older age in the Boreal compared to the Tethys.…”

Linking an Early Triassic delta to antecedent topography: Source-to-sink study of the southwestern Barents Sea margin

“…However, in the Early Triassic of the Barents Sea, several of these hampering issues are alleviated: Biostratigraphic dating has a relatively high resolution (~1 m.y.) due to rapid evolutionary diversification after the Permian-Triassic extinction event (e.g., Chen and Benton, 2012); the climate during this period has been the subject of several studies, as it was a time of major climatic shifts (Péron et al, 2005;Sellwood and Valdes, 2006;Svensen et al, 2009;Hochuli and Vigran, 2010;Sun et al, 2012); and minor tectonic change has occurred in this area since the Carboniferous (Bugge et al, 1995;Riis, 1996;Gudlaugsson et al, 1998;Hall, 2015).
