Professor Chris Kendall GEOL 716: Variations in Sequence Stratigraphy University of South Carolina Spring 2006 Octavian Catuneanu, 2002 Professor Chris Kendall EWS 304 kendall@sc.edu 777.2410 GEOL 716 Lecture 3: Sequence Stratigraphy

Sequence Stratigraphy A framework of genetically related stratigraphic facies geometries and their bounding surfaces used to determine depositional setting

Sequence Stratigraphy Subdivision & interpretation of sedimentary record using a framework surfaces seen in outcrops, well logs, & 2-D and 3-D seismic. Include: Surfaces of erosion & non-deposition (sequence boundaries) Flooding (trangressive surfaces [TS] &/or maximum flooding surfaces [mfs]) This framework used to predict the extent of sedimentary facies geometry, lithologic character, grain size, sorting & reservoir quality GEOL 716 Lecture 3: Sequence Stratigraphy
