Abstract
- Planar-tabular cross-stratified sets in the Torridonian sandstones (Precambrian) of northwest Scotland are described whose cross-strata are inclined at wide angles to local paleocurrent directions. Sedimentary structures within the sets suggest that they formed on the point bars of shallow streams. A braided stream environment seems likely, although similar structures have not as yet been observed in the deposits of modern braided streams. The preferred direction of migration of streams could be of great paleogeographic significance.
