GRAVEL IMBRICATION ON THE DEFLATING BACKSHORES OF BEACHES ON PRINCE-EDWARD-ISLAND, CANADA

Discoidal- to prolate-shaped pebble- to cobble-size clasts on the part ially deflated beach backshore of the north shore of Prince Edward Isl and display a pronounced imbrication. The direction of imbrication cor relates with the orientation of wind-shadow sand ridges behind the cla sts. The imbrication is created by the selective removal of sand parti cles beneath the upwind margins of the clasts during deflation. This f abric can be preserved and has the potential to provide a means for th e measure of paleowind orientation in partially deflated deposits in s horeline and possibly interdune areas.
