  • Info Sandstone How is it Formed?

    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.
