Storms and Shallow Marine Deposits

Marine Deposition. Most sediments eventually get transported into the oceans. In the sedimentary record, shallow marine deposits are the most abundant due to their large volume and the low erosion rates in those environments. Marine deposits above sea level are often uplifted by tectonics which exposes them to significant erosion.
