Definition
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
Aplite is a fine-grained granite composed mainly of feldspar and quartz

Formation
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.
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 vs Aplite 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. Teschenite vs Aplite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Teschenite and Properties of Aplite. Learn more about Teschenite vs Aplite in the next section. The interior uses of Teschenite include Countertops, Decorative aggregates, Entryways, Homes and Interior decoration whereas the interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Teschenite and Aplite, they have various applications in construction industry. The uses of Teschenite in construction industry include As dimension stone, Building houses or walls, Cement manufacture, Construction aggregate, For road aggregate and that of Aplite include As dimension stone.
More about Teschenite and Aplite
Here you can know more about Teschenite and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Teschenite and Aplite consists of mineral content and compound content. The mineral content of Teschenite includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Teschenite vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Teschenite is available in dark grey to black colors whereas, Aplite is available in black, grey, orange, pink, white colors. Appearance of Teschenite is Veined and Shiny and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Teschenite vs Aplite. The hardness of Teschenite is 7 and that of Aplite is 6.5. The types of Teschenite are Not Available whereas types of Aplite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Teschenite is black while that of Aplite is white. The specific heat capacity of Teschenite is Not Available and that of Aplite 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.Teschenite is impact resistant, pressure resistant, wear resistant whereas Aplite is heat resistant, wear resistant.
