description |
The Middle Jurassic to Lower Cretaceous Adventdalen Group. TSE 6: Upper Middle Jurassic to Lower Cretaceous – continental platform. A prominent provenance shift to a northerly source area is recorded in the succession above the major flooding surface that caps the Kapp Toscana Group (Fig. a). The Bathonian to Ryazanian succession is mudstone-dominated and includes up to 100 m thick organic-rich units of the Janusfjellet Subgroup in western Spitsbergen. These mudstones are locally intersected by Kimmeridgian prograding shoreface or deltaic wedges (i.e., the OppdalsÃ¥ta Member) sourced from the northwest (Fig. b). Uplift in the north caused by the opening of the Amerasian Basin and volcanism related to the emplacement of the High Arctic Large Igneous Province (HALIP) forced an extensive fluvio-deltaic system to prograde far southward onto the Barents Shelf. The fluvio-deltaic deposits are assigned to the upper part of the Rurikfjellet and the Helvetiafjellet formations (Fig. c). A regional flooding surface, whose development coincides with the Aptian Oceanic anoxic event 1a (OAE1a), separates the deltaics from storm-dominated shelf deposits of the Carolinefjellet Formation. In central Spitsbergen, HALIP volcanism is mostly recorded as sill intrusions, which forms extensive cliff bands in the landscape (Fig. d). |
