Abstract

An investigation was made of the effect of morphogenic factors upon platform morphometry in Gaspe. Quasi-horizontal platforms a.re cut into steeply dipping flysch, consisting of shale, graywacke and argillites. Tidal range determines platform slope, midtide level the mean elevation of platforms. The cliff-platform junction develops closer to Mean Higher High Water than to other tidal levels. An assessment was also made of other factors such as offshore slope, platform width, rock dip, rock hardness and debris size upon platform gra­dient.

It is concluded that although lithology is dominant in the control of the micro-morphometry of platforms, it is a combination of morphogenic factors which is responsible for their macro-morphometric characteristics.
