The Entrada Sandstone was once a massive desert, full of shifting dunes of fine-grained sand. The grains are nearly spherical so, when packed together, they formed a rock that is very porous (full of tiny spaces).
WebThis process is called cementation. Once the sediment is cemented together, sedimentary rock is formed. Cementation could be modeled a number of ways, such as pouring glue onto a pile of rice grains. Examples … WebThe fluid flow causes sand grains to saltate up the stoss (upstream) side of the bedform and collect at the peak until the angle of repose is reached. At this point, the crest of granular material has grown too large and will be overcome by the force of the moving water, falling down the lee (downstream) side of the dune.
