Stable isotopic evidence for methane seeps in Neoproterozoic postglacial cap carbonates

Article Abstract:

The existing glacial deposit are covered with a 1-5-m-thick cap carbonates which are associated with negative carbon isotope excursions. These carbonate rocks were the result of destabilization of methane hydrates during deglaciation and concomitant flooding of continental shelves.
