Paleocurrent analysis is the study of the direction of ancient water or wind currents based on the orientation of sedimentary structures such as cross-bedding, ripple marks, and flute casts. This analysis is important for reconstructing paleoenvironments, sediment transport pathways, and the depositional history of sedimentary basins.
