current-bedding

(geology) Cross-bedding resulting from water or air currents.

In a sedimentary rock, bedding which is oblique to the ‘lie’ of the formation as a whole. The structure is original, and not due to tilting or folding. It develops when sandbanks are built up in shallow water, or where sand dunes accumulate from wind-blown sands; here the pattern of bedding reproduces all or part of the outline of the dunes.
