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.
Siltstone is a type of sedimentary rock which is formed from fine rock particles. As the particles of eroded rock travel along with water, the edges of the rock are worn-out by water into a rounded shape.

Aplite vs Siltstone 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 Siltstone characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Siltstone. Learn more about Aplite vs Siltstone 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 Siltstone include Decorative aggregates and Interior decoration. Due to some exceptional properties of Aplite and Siltstone, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Siltstone include Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement, Raw material for the manufacture of mortar.
More about Aplite and Siltstone
Here you can know more about Aplite and Siltstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Siltstone 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 Siltstone includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz, Sand, Silica, Silt. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Siltstone, 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, Siltstone is available in brown, red, reddish brown colors. Appearance of Aplite is Veined or Pebbled and that of Siltstone is Rough. Properties of rock is another aspect for Aplite vs Siltstone. The hardness of Aplite is 6.5 and that of Siltstone is 6-7. The types of Aplite 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 Aplite and Siltstone is white. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Siltstone is Not Available. 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 Siltstone is heat resistant, impact resistant, pressure resistant, water resistant.
