1. Sedimentary structures are rarely evident due to a high degree of recrystallisation.2. As a result, the two categories often contain the same sedimentary structures . 3. A variety of sedimentary structures have been reported from the Bass Formation. 4. An "'antidune "'is an upper flow regime sedimentary structure found in aquatic environments. 5. The Skaergaard intrusion in Greenland is a prime example of these quasi-sedimentary structures . 6. Parting lineation is a sedimentary structure commonly found on the surface of parallel-laminated sandstones. 7. A different vertical progression of sedimentary structures characterize high-density turbidites. 8. This process can destroy sedimentary structures that were present upon deposition of the sediment. 9. Although few fossils are normally present, the original texture and sedimentary structures are preserved. 10. Sedimentary structures are well preserved in most of the Belt rocks despite their great age.
