Formation
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

More about Claystone and Aplite
Here you can know more about Claystone and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Claystone and Aplite 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 Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all . When we have to compare Claystone vs Aplite, 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, Aplite is available in black, grey, orange, pink, white colors. Appearance of Claystone is Rough and Dull and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Claystone vs Aplite. The hardness of Claystone is 3.5-4 and that of Aplite is 6.5. The types of Claystone are Not Available whereas types of Aplite 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 Aplite is white. The specific heat capacity of Claystone is 0.92 kJ/Kg K and that of Aplite is 0.79 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 Aplite is heat resistant, wear resistant.
