Where do Sedimentary Rocks come from?

The products of mechanical and chemical weathering are the ‘raw material’ for the sedimentary rocks.

These products are swept from their original location by transporting materials (fluids) like air or water. This is what we mentioned on our previous post about the depositional system concept. These processes can occur in Continental (terrestrial), Marine, Carbonate, and/or Evaporites Environments, which are many times coupled. Some examples are shown below

1. Continental (Fluvial -rivers-, Eolian -deserts-, Lacustrine -lakes-, and Glacial systems)

2. Marine Environments

3. Evaporites
