during the past 50 years. These include: (1) there is a close interrelation in time and space of environment, sedimenta- tion, fauna, structure, and hydrocarbon distribution; (2) in the generally regressive basin-filling cyclic sequence, gross lithologic units are diachronic: (3) benbhonic-foraminifera! zwtation provides isochrons and paleoenvironmental indica- tors; (4) within each cycle, deltaic depocenters can be recognized; (5) elements of deltaic and littoral morphology

EDWARD 8. PICOU, JR.-Biographical Sketch

Edward 8. Picou, Jr. is a native of Baton Rouge, La. He majored in geology at Louisiana State University where he earned his B.S. degree in 1955. After grad- uation, he served two years as an officer with the Corps of Engineers, mostly in Korea. He joined Shell Oil Company in 1957 as a rnicropalwntologist. As- signments with Shell's Ex- ploration Divisions have included duty stations in Baton Rouge, New Orle-
