Further east, the Ponkapoag Fault cuts out the Pennsylvanian sedimentary rocks, so that the Ordovician-Silurian Quincy Granite and the Cambrian Braintree Formation directly contact the Dedham Granite. The Ponkapoag Fault, near Weymouth, also splits up the Wamsutta Formation between the Norfolk Basin and the nearby Narragansett Basin.
