Diatomite is a friable light-colored sedimentary rock that is mainly c Sedimentary rocks are formed from deposits of pre-existing rocks or pieces of once-living organism that accumulate on the Earth's surface. If sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock. These rocks often have distinctive layering or bedding and create many of the picturesque views of the desert southwest. Sedimentary rocks are one of three main rock types, [Tendency to chemical cement. Ash: unconsolidated fragmentsThe Chalk Sea. Chalk is effectively the starting point o Sandstone is a clastic sedimentary rock comprised of sand-sized particles about .1 to .2 mm in size. It is usually tan, brown, or reddish in color, and often (but not always) displays noticeable layers. The sand grains are most often made of quartz, cemented together by calcite or silica.Chalk is a sedimentary rock of unusually high homogeneity on the scale wher e physical properties. are measur ed, but the properties fall in wide ranges.
