PESA WA October Technical Evening Talk —  

By Matt Fittall

A core group of PESA geoscientists gathered at The Globe on the evening of October 2nd to learn about the impact of new numerical modelling of deposition in wave influenced deltas in the interpretation of deltaic sequences and their facies distributions. Dr Willis and his co-workers showed how this work challenges the paradigm of a prograding equilibrium shoreface profile and a gradual upward- coarsening facies progression with a sharp-based shoreface succession generated by a relative sea-level fall.

In his presentation Brian Willis demonstrated that differences in...
