Claystone rock.

A claystone is a lithified and non-cleavable mudrock. In order for a rock to be considered a claystone, it must consist of at least fifty percent clay ( phyllosilicates ), whose particle measures less than 1/256 of a millimeter in size. Clay minerals are integral to mudrocks, and represent the first or second most abundant constituent by volume. Taking into consideration that sedimentary rocks, such as sandstone, claystone or shale, cover a substantial part of the Earth’s surface, knowledge of their behaviour during loading is very important. The stress-strain curve for axial deformations is the best way to test rock elasticity and to determine the elastic modulus (Young’s modulus).The hardness of Claystone is 3.5-4 and that of Siltstone is 6-7. The types of Claystone are Not Available whereas types of Siltstone are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Siltstone is white.Siltstone is a sedimentary rock composed mainly of silt-sized particles. It forms where water, wind, or ice deposit silt, and the silt is then compacted and cemented into a rock. Silt accumulates in sedimentary basins throughout the world. It represents a level of current, wave, or wind energy between where sand and mud accumulate.
