Definition
Aplite is a fine-grained granite composed mainly of feldspar and quartz
Teschenite is coarse- to fine-grained, dark-coloured intrusive igneous rock that usually occurs in sills, dikes and irregular masses and is always altered to some extent

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.
Teschenite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

Aplite vs Teschenite 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 Teschenite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Teschenite. Learn more about Aplite vs Teschenite 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 Teschenite include Countertops, Decorative aggregates, Entryways, Homes and Interior decoration. Due to some exceptional properties of Aplite and Teschenite, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Teschenite include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate.
More about Aplite and Teschenite
Here you can know more about Aplite and Teschenite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Teschenite 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 Teschenite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Teschenite, 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, Teschenite is available in dark grey to black colors. Appearance of Aplite is Veined or Pebbled and that of Teschenite is Veined and Shiny. Properties of rock is another aspect for Aplite vs Teschenite. The hardness of Aplite is 6.5 and that of Teschenite is 7. The types of Aplite are Igneous rock whereas types of Teschenite are Igneous rock. 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 Teschenite is black. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Teschenite is 0.79 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 Teschenite is impact resistant, pressure resistant, wear resistant.
