Eolian transport textures on the surfaces of sand grains of Early Triassic age Available to Purchase

The surface textures of quartz sand grains from a Lower Triassic sandstone unit are almost identical to eolian sands from modern hot deserts, suggesting similar environments. This is the earliest example known of eolian surface textures unmodified by diagenesis; it shows how studies of surface textures of pre-Pleistocene sand grains may provide information about their depositional environments and subsequent diagenetic history.
