Abstract

The sediment sequence occurring the Hawkesbury Sandstone on the Sydney coast would be relatively mundane were it not for the profound way in which it has been deformed. Other deposits of like origin and similar age are relatively untouched while one deposit in question has now been irrevocably changed. This location represents an as yet unknown type of deformation and will be characterized. The deformation experience in this location seems to be linked to both pore fluid pressure and lithological variation. In the event of deformation these variations allowed the rocks to take shape in various fabrics including “Flotsam” and Sheath Folds. Structures like these may be advantageous to people of interests in understanding anisotropies in potentially economic media.

Biography

Reid Hernon love of rocks began early when his dad took him on a cave tour. Several rock collections and mineral digs later Reid decided Geology was for him. His four years studying Geology have taken him on two field camps to Utah and New Mexico which includes locations as visually and geologically spectacular as the Grand Canyon and Meteor Crater. In the early 2014 calendar year he went to Sydney, Australia and took his love of rocks with him. He will be presenting his findings at this year’s conference. After graduation in May he will be pursuing a career applying his skills and expertice to the rocks he loves.
