Definition
Aplite is a fine-grained granite composed mainly of feldspar and quartz
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

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.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

Aplite vs Boninite 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 Boninite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Boninite. Learn more about Aplite vs Boninite 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 Boninite include Decorative aggregates, Homes and Kitchens. Due to some exceptional properties of Aplite and Boninite, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Boninite include As a flux in the production of steel and pig iron, As a sintering agent in steel industry to process iron ore, As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Aplite and Boninite
Here you can know more about Aplite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Boninite 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 Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Boninite, 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, Boninite is available in bluish - grey, brown, green, grey colors. Appearance of Aplite is Veined or Pebbled and that of Boninite is Dull and Soft. Properties of rock is another aspect for Aplite vs Boninite. The hardness of Aplite is 6.5 and that of Boninite is 7. The types of Aplite are Igneous rock whereas types of Boninite are Basalt. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite and Boninite is white. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Boninite 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 Boninite is heat resistant, impact resistant, pressure resistant, wear resistant.
