Sample Progress Report Progress Report Stratigraphic architecture of Deep-Ramp Carbonates: Implications for Deposition of Volcanic Ashes, Salona and Coburn Formations, Central Pennsylvania by John Lerner SCOPE AND PURPOSE The Late Middle Ordovician-age Salona and Coburn formations of central Pennsylvania show cyclic patterns on a scale of tens of meters. Little research has been done on sequence stratigraphy of deep-water mixed carbonate/siliciclastic systems, and a depositional model for this environment is necessary to understand the timing and processes of deposition. The stratigraphic position of the bentonites at the base of the larger cycles is significant because it indicates that they accumulated during a time of non-deposition in a deep water environment.
