Formation
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.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

Aplite vs Claystone Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Aplite vs Claystone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Claystone. Learn more about Aplite vs Claystone in the next section. The interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads whereas the interior uses of Claystone include Decorative aggregates, Entryways, Floor tiles, Homes and Interior decoration. Due to some exceptional properties of Aplite and Claystone, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Claystone include As a sintering agent in steel industry to process iron ore, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Aplite and Claystone
Here you can know more about Aplite and Claystone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Claystone consists of mineral content and compound content. The mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Claystone includes Biotite, Chlorite, Feldspar, Micas, Muscovite or Illite, Plagioclase, Pyrite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Claystone, the texture, color and appearance plays an important role in determining the type of rock. Aplite is available in black, grey, orange, pink, white colors whereas, Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow colors. Appearance of Aplite is Veined or Pebbled and that of Claystone is Rough and Dull. Properties of rock is another aspect for Aplite vs Claystone. The hardness of Aplite is 6.5 and that of Claystone is 3.5-4. The types of Aplite are Not Available whereas types of Claystone are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite and Claystone is white. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Claystone is 0.92 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Aplite is heat resistant, wear resistant whereas Claystone is heat resistant, impact resistant.
