Large-scale planar crossbedded arkosic sandstones of the Deweras Group display small-scale features that are diagnostic of aeolianites, including em-scale inversely-graded ripple-cross-laminated "subcritically-climbing translatent strata" (Hunter, 1976), wedge-shaped massive grainflows (avalanche deposits), and pinstripe lamination. These are among the oldest authenticated aeolianites in the world (Master, 1995).
