Archaeological Significance
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.
Charnockite is an intrusive igneous rock which is very hard and is formed due to weathering of existing rocks.

Aplite vs Charnockite 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 Charnockite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Charnockite. Learn more about Aplite vs Charnockite 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 Charnockite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Aplite and Charnockite, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Charnockite include As dimension stone.
More about Aplite and Charnockite
Here you can know more about Aplite and Charnockite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Charnockite 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 Charnockite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Charnockite, 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, Charnockite is available in black, grey, orange, pink, white colors. Appearance of Aplite is Veined or Pebbled and that of Charnockite is Veined or Pebbled. Properties of rock is another aspect for Aplite vs Charnockite. The hardness of Aplite is 6.5 and that of Charnockite is 6-7. The types of Aplite are Igneous rock 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 Aplite and Charnockite is white. The specific heat capacity of Aplite is 0.79 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.Aplite is heat resistant, wear resistant whereas Charnockite is heat resistant, wear resistant.
