Available in Lots of Colors and Patterns, Smooth to touch, Very fine grained rock
Available in Lots of Colors and Patterns, It is One of the Oldest, Strongest and Hardest Rock
Archaeological Significance
Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

More about Claystone and Charnockite
Here you can know more about Claystone and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Charnockite consists of mineral content and compound content. The mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz and mineral content of Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Claystone vs Charnockite, the texture, color and appearance plays an important role in determining the type of rock. Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors whereas, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Claystone is Rough and Dull and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Claystone vs Charnockite. The hardness of Claystone is 3.5-4 and that of Charnockite is 6-7. The types of Claystone are Claystone whereas types of Charnockite are Enderbite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Claystone and Charnockite is white. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Charnockite is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Claystone is heat resistant, impact resistant whereas Charnockite is heat resistant, wear resistant.
