A consideration of the major source areas generated by plate tectonics mechanisms suggests that the premise is valid and can be expanded to include sandstone varieties other than gray-wacke, but more data on modern sand are needed to refine the concept. The potential usefulness of such contrasts in sandstone mineralogy and chemistry is demonstrated by comparing the composition of several ancient sandstone units (mainly from the Appalachian-Caledonian belt) for which plate tectonics basin models have been proposed.
