Abstract

Summary

This study presents a comparison of integrated palynostratigraphy from two significant Triassic successions: the Bunter Sandstone storage complex in the Southern North Sea and the Sassendalen and Kapp Toscana groups on the Barents Shelf. Each study region serves distinct purposes—CO storage in the Southern North Sea and hydrocarbon exploration on the Barents Shelf—yet both require refined stratigraphic frameworks for effective resource development. For the Southern North Sea, analysis of 500 samples from 14 wells led to the establishment of a new palynozonation, addressing a critical gap in regional biostratigraphy and improving cross-border correlation between the UK and Dutch sectors. On the Barents Shelf, palynological and macrofossil data were integrated with sequence stratigraphy across 42 localities, refining chronostratigraphy and knowledge of the spatio-temporal distribution of reservoir sands. Our findings highlight how climate and environmental shifts influenced Triassic vegetation and sedimentation, with species turnover paralleling major marine transgressions and/or global climatic changes. The frameworks developed offer broader relevance, with potential applications to other Triassic successions, including those in the East Irish Sea Basin and Central and Northern North Sea.
