Comparative Analysis of the Sverdrup and East Barents Sedimentary Basins

Resumo

A comparative analysis of two large Arctic sedimentary basins was performed: the Sverdrup and East Barents, with emphasis on the quantitative parameters of sedimentation in the Mesozoic, determined by A.B. Ronov’s volumetric method. The similarities and differences of both basins are revealed, in particular, in sediment accumulation areas, in masses of sedimentary material per time unit, and in gross sand ratio. It was concluded that at the end of the Paleozoic and in the Mesozoic, both basins were close to each other but did not merge into one structure. In the Cenozoic, the distance between the basins increased due to spreading of the Eurasian Basin.
