Eight samples of brachiopod shell material have been analyzed for their strontium isotope composition in order to more accurately date Lower to Upper Permian siliceous biogenic strata of Spitsbergen (Kapp Starostin Formation) and the southern Barents Sea (Røye Formation). The results are interpreted as showing a mid-Artinskian age for the basal Vøringen Member of the Kapp Starostin Formation and a range of late Artinskian to Roadian for the overlying part of this unit. The upper part of the Røye Formation yields ages in the range Roadian to Wuchiapingian. These results are consistent with available biostratigraphic data and confirm the potential of strontium isotope stratigraphy for developing a more accurate chronology of the widespread spiculite deposits that characterize the northern margin of Pangea in late-Early Permian to Late Permian time and which constitute a potential target for petroleum exploration. 3 Journal of Petroleum Geology 33 ARTICULO Ehrenberg, S.N. 13453 McArthur, J.M. 45758 Thirlwall, M.F. 45759 175093 175093 0 0 0 0 242912 BAAB BAAB 2026-03-05 200046975 0 200046975 2026-03-05 18:52:37 2026-03-05 ARTICULO
