Abstract

Ripple marks, cross bedding, and groove casts are examples of directional features of sediments. Systematic downcurrent variations in grain size or mineral composition are examples of scalar properties. Directional features and scalar properties of sediments are used to determine paleocurrent direction. The integration of paleocurrent data with environmental information yields a paleogeographic map, from which prediction of favorable areas for wildcat exploration and the exploitation of wildcat discoveries can be made. [A study of the Hartshorn Formation, Arkoma Basin, Okla., is cited as an example.]
