Commonly discontinuous crack patterns, sometimes polygonal in plan view with V- to U-shaped cross-sectional profiles, formed in mud laminae and thin beds commonly within successions of interbedded sandstones and mudstones, due to dewatering in a subaqueous setting (and not due to desiccation under subaerial exposure) (Fig. 1).
