Sandstone is a sedimentary rock that consists mainly of sand grains. During the sedimentation of sand grains, clays, limestones, gravel, shale, feldspars and other rock fragments are also deposited. Due to weathering, the originally yellow-brown sandstone turns grey. The occurrence of some oxides and other minerals colours the sandstone brownish red.
