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.
Itacolumite is a sedimentary rock which forms from cemented sand-sized clasts and is a type of sandstone.

Aplite vs Itacolumite 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 Itacolumite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Itacolumite. Learn more about Aplite vs Itacolumite 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 Itacolumite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Aplite and Itacolumite, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Itacolumite include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Aplite and Itacolumite
Here you can know more about Aplite and Itacolumite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Itacolumite 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 Itacolumite includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Itacolumite, 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, Itacolumite is available in beige, black, brown, cream, dark brown, green, grey, light green, light to dark grey, pink, red, white, yellow colors. Appearance of Aplite is Veined or Pebbled and that of Itacolumite is Rough. Properties of rock is another aspect for Aplite vs Itacolumite. The hardness of Aplite is 6.5 and that of Itacolumite is 6-7. The types of Aplite are Igneous rock whereas types of Itacolumite are Sandstone. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite and Itacolumite is white. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Itacolumite is 0.92 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 Itacolumite is heat resistant, impact resistant, pressure resistant.
