Quasi-Planar Adhesion Stratification--An Eolian Structure Formed in Wet Sand

Abstract

ABSTRACT Quasi-planar adhesion stratification is formed by the deposition of windblown sand on dune, beach, and other sandy surfaces that are wet but unmarked by adhesion ripples. The absence of adhesion ripples may result either from the insufficient wetness of the surface or from the tendency for raindrop impacts to inhibit ripple growth. The stratification is characterized by its indistinctness and by small-scale crenulations that result from the slight roughness of the depositional surface.
