Siliciclastics Shelf Margins Revisited Andy Petter, Cornel Olariu & Ron Steel
University of Texas at Austin
26-27 June 2009
The course aim is to present new ideas on morphology, architecture and accretion of shelf & shelf margin prisms. It is recommended for geologists with an interest in shelves, deepwater slopes and evolving sequence stratigraphy concepts.
The short course will focus on :
shelf transit principles and the importance of supply, sea-level, shelf width and shelf/coastal plain gradient,
shelf and shelf-slope break variability; shelf morphology in high- and low- supply conditions,
evolution and architecture of sediment-delivery systems (deltas) on the shelf,
slope channels, sediment deposition vs by-pass on the slope, and hyperpycnal flow as a new slope-delivery mechanism
sea-level driven lowstand vs.supply-driven highstand models for shelf margin accretion and fans,
Rules of Thumb for predicting deepwater sands.
Lectures will be interspersed with well-log and seismic exercises.
