Physical Properties of Sandstone. Physical properties of rocks are used to identify the type of rocks and to discover more about them. There are various physical properties of Sandstone like Hardness, Grain Size, Fracture, Streak, Porosity, Luster, Strength etc which defines it.
Sandstone Formation. Formation of the sandstones are 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. Grain sizes in sands are defined (in geology) within the range of 0.0625 mm to 2 mm (0.0025–0.08 inches).
