Mud indicates settling out of suspension. Shallow water sand bodies result from ocean current and wave action. Sedimentary environments may change without a change in hydraulic regime. Changes in the sedimentary environments correspond to changes in the hydraulic regime . Sediments are cemented on the sea floor.
Sediments remain unconsolidated in the environment of deposition and on the sea floor.
Periodic exposure of sediments during deposition does not affect the deposits. Signs of sedimentary facies are destroyed during low-grade metamorphism. Sedimentary facies discernible after low-grade metamorphism. Reproduced with permission of the University of British Columbia. Email the Webmaster .
