The Cenomanian-Turonian transition on the Peruvian margin

open access: yesCretaceous Research, 1993
Abstract In Peru, various deposittonal sequences can be recognized during the late middle Cenomanian to early Coniacian timespan, most of which seem to have an eustatic origin. For instance, the early late Cenomanian, late early Turonian and early Coniacian maximum floodings identified in Peru coincide with well-known global eustatic events.
