Neoproterozoic chemostratigraphy and correlation of the Port Askaig glaciation, Dalradian Supergroup of Scotland
The 13C 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 13Ccarb values, jumping sharply to +11.7 ne...
