Two examples of sedimentary rocks are slate (fine silt) and chalk (shell remains of sea creatures).
Conceptually, that is the same texture we see in igneous and metamorphic rocks, but NOT in clastic sedimentary rocks. Chemical sedimentary rocks form because of the precipitation of crystals from aqueous (water) solutions and from chemical residues.ediment is a general term that indicates loose grains (such as the sand at the beach) and chemical precipitates (such as crystals of salt). Sedimentary rocks can be subdivided in three categories: clastic, chemical, and biochemical sedimentary rocks.
