Late Permian–earliest Triassic high-resolution organic carbon isotope and palynofacies records from Kap Stosch (East Greenland)

摘要: Abstract During and after the end Permian mass extinction terrestrial marine biota underwent major changes reorganizations. The latest earliest Triassic is also characterized by negative carbon isotope shifts reflecting fundamental in cycle. present study documents a high-resolution bulk organic record palynofacies analysis spanning Permian–earliest of East Greenland. An almost 700 meter thick composite section from Kap Stosch allowed discriminating 6 chemostratigraphic intervals that provide basis for correlation with other coeval records across world, recognition basin wide transgressive–regressive events documenting tectonic activity during opening Greenland–Norway Basin. identification main factors influenced signal (Griesbachian to Dienerian) was possible due combination isotope, Rock-Eval data. Two isotopic can be correlated recorded sections globe. A first shift precedes base as defined occurrence conodont Hindeodus parvus Meishan reference section, second one coincides suggested Griesbachian–Dienerian boundary. This new extended Boreal Realm regional global cycle signals interval between Palaeozoic onset Mesozoic.
