Svalbard Tonian and Cryogenian Carbonate Analysis with Clumped Isotope Thermometry

Data set includes calcites and dolomites from pre-glacial and syn-glacial strata surrounding the first Cryogenian (717-635 Ma) glaciation from NE Svalbard. Carbonates from pre-glacial strata come from the Backlundtoppen Formation and the Russøya Member of the Elbobreen Formation; glacial carbonates come from the Elbobreen Formation Petrovbreen Member. Petrovbreen Member samples include carbonates interpreted as both detrital clasts sourced from pre-glacial stratigraphy and syn-glacial diamictite matrix and soft sediment clasts (Mackey et al., 2020).
