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.
Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.

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 Anthracite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Anthracite. Learn more about Aplite vs Anthracite 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 Anthracite include Not yet used. Due to some exceptional properties of Aplite and Anthracite, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Anthracite include Cement manufacture, For road aggregate, Making natural cement, Steel production.
More about Aplite and Anthracite
Here you can know more about Aplite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Anthracite 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 Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all . When we have to compare Aplite vs Anthracite, 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, Anthracite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Aplite is Veined or Pebbled and that of Anthracite is Veined or Pebbled. Properties of rock is another aspect for Aplite vs Anthracite. The hardness of Aplite is 6.5 and that of Anthracite is 1-1.5. The types of Aplite are Not Available whereas types of Anthracite are Semi-anthracite and Meta-anthracite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite is white while that of Anthracite is black. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Anthracite is 1.32 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 Anthracite is heat resistant, water resistant.
