chevron marks
chevron marks A type of sole structure characterized by a linear pattern of small, V-shaped ridges formed by the dragging of an object over the surface of a viscous mud. The V-shapes close in the down-current direction, enabling the chevron marks to be used as a palaeocurrent indicator. See PALAEOCURRENT ANALYSIS.
