Neoproterozoic chemostratigraphy and correlation of the Port Askaig glaciation, Dalradian Supergroup of Scotland

Abstract:: The δ13C of preglacial carbonates beneath the glaciogenic Port Askaig Formation falls from +5‰ to negative values, while least-altered 87Sr/86Sr values are close to 0.7067. Postglacial 'cap carbonates' of the Bonahaven Formation begin with negative δ13C(carb) values, jumping sharply to +11.7‰ near the top, which we correlate with excursions above the Elbobreen-Wilsonbreen glaciations of Svalbard and putative Sturtian (not Varanger) glaciations elsewhere, dated at c. 720 Ma. Much of the succee...
