Title: Seismic Stratigraphic Identification of Submarine Fans--Espirito Santo Basin, Offshore Brazil: ABSTRACT

Author(s): C. Lucchesi, P. Araripe, V. Beraldo

Article Type: Meeting abstract


Seismic stratigraphic analysis of the Upper Cretaceous/middle Eocene sedimentary section of the Espirito Santo basin reveals two distinctive, seismic supersequences which were deposited in open-marine conditions. Several submarine fan-forming episodes are identified. The lower supersequence of Late Cretaceous to Paleocene is a sedimentary wedge onlapping a tilted Albian/Cenomanian carbonate shelf. The upper supersequence, deposited from early to middle Eocene, displays a progradational pattern. Within this thick and well-defined Tertiary section, several depositional sequences are recognized, some closely related to global relative sea level changes.

The integration of data from 16 wells with seismic lines led to the identification and mapping of several seismic features which are interpreted as turbidite fans.
