What is sandstone?



These sedimentary rocks originated as loose grains of rock materials, predominantly quartz but occasionally felspar or some other mineral. These materials, eroded from older rocks, have been sorted and deposited by the physical action of water and sometimes wind, to form beds. Consolidation ensues over millions of years by processes similar to those responsible for the formation of limestones. The cement of sandstone may be rich in various materials; Silica, Iron, Calcium Carbonate, all of which contribute to the final colour and characteristics of the sandstone. Sandstone beds also posses natural jointing systems.
