Mostly sandstones are resistant to weathering and are also very much easy to work. This makes sandstone a popularly used building and paving material.
Origin of Sandstone
Sandstones are basically clastic in origin. They are originated from the hard grains, which may be parts or fragments of a pre-existing rock or other mineral crystals. The process of sedimentation plays a major role in the formation of sand stones. Sandstones are formed mainly in terrestrial and marine environments.
Just like sand, sandstones are also available in a wide array of colours including brown, yellow, red, gray, tan and white. They are also available in various sizes and finishes. Topographic features also effect the color of sand stones.
