It is formed from sediment deposited by rivers, the sea, or by the wind, so there are many types of sandstone. Origins of Sandstone. Sandstones are clastic in origin (as opposed to organic, like chalk and coal, or chemical, like gypsum and jasper). They are formed from cemented grains that may either be fragments of a pre-existing rock or be mono-minerallic crystals. The cements binding these grains together are typically calcite, clays and silica. This banded sample exhibits bands of red, gray, and buff due to iron oxidation. Sandstone is formed from beach sand-sized quartz grains that are glued together ...What Type of Rock is Sandstone. Sandstone is a type of sedimentary rock.
