Posted on August 15, 2018 GeoCon No Comments Pic of the day #20 (a) Cross section showing the geometry of ramps and flats along a thrust fault. The fault geometry is shown prior to displacement on the fault. (b) Cross section illustrating hanging-wall and footwall flats and ramps. Segment AB is a hanging-wall flat on a footwall flat. Segment BC is a hanging-wall flat on a footwall ramp. Segment CD is a hangingwall ramp on a footwall flat, and segment DE is a hanging-wall flat on a footwall flat.
