Definition
Aplite is a fine-grained granite composed mainly of feldspar and quartz
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface

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.
Basaltic Trachandesite is a fine-grained, hard rock that forms when bits of lava shoot out of volcanoes.

More about Aplite and Basaltic Trachyandesite
Here you can know more about Aplite and Basaltic Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Basaltic Trachyandesite 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 Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Basaltic Trachyandesite, 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, Basaltic Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Aplite is Veined or Pebbled and that of Basaltic Trachyandesite is Dull and Soft. Properties of rock is another aspect for Aplite vs Basaltic Trachyandesite. The hardness of Aplite is 6.5 and that of Basaltic Trachyandesite is 6. The types of Aplite are Igneous rock whereas types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. 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 Basaltic Trachyandesite is white to grey. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Basaltic Trachyandesite 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 Basaltic Trachyandesite is heat resistant, pressure resistant, wear resistant.
