Abstract

Two new methods are presented for the determination of paleocurrent directions from three-dimensional exposures of oblique cuts through individual trough limbs and two-dimensional exposures of sets of trough cross-strata. Three-dimensional exposures of trough limbs can be measured and treated statistically on a stereographic plot to determine the average trough-axis orientation. In two-dimensional exposures, characteristic asymmetry of the basal scour surface and truncation of foreset laminae can aid in estimation, within about 25^o, of paleocurrent direction. - from Authors
