Linking sediment supply variations and tectonic evolution in deep time, source-to-sink systems—The Triassic Greater Barents Sea Basin

Abstract Triassic strata in the Greater Barents Sea Basin are important records of geodynamic activity surrounding catchments and sediment transport Arctic basins. This study is first attempt to investigate evolution these source areas through time. Our analysis budgets from subsurface data application BQART approach estimate catchment properties shows that (1) during Lower Triassic, supply was at its peak basin comparable biggest modern-day river systems, which supplied by tectonically active orogens; (2) Middle load significantly lower but still top 10 largest modern rivers; (3) Upper increased again Carnian; (4) there a large mismatch (70%) between modeled estimated Carnian. These results consistent with succession being deposited under influence volcanic event ever Permian-Triassic boundary (Siberian Traps) concurrent climatic changes Carnian Pluvial Event final stages Northern Ural orogeny. They also provide better understanding impacts on sedimentary systems improve our knowledge continental-scale transport.
