Web in geology, a graded bed is a bed characterized by a systematic change in grain or clast size from bottom to top of the bed. Piling of sediment down the front of a dune or ripple d. Carbonate cement is commonly present as a sandstone/mudstone contact. Web these are called cross bedded laminae, because they form at an angle to the horizontal nature of the main bed. Sand grains bounce up the stoss side of a ripple, and then tumble down the lee side.
