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.
Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Aplite vs Phonolite 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 Phonolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Phonolite. Learn more about Aplite vs Phonolite 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 Phonolite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Aplite and Phonolite, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Phonolite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories, Production of glass and ceramics.
More about Aplite and Phonolite
Here you can know more about Aplite and Phonolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Phonolite 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 Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Phonolite, 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, Phonolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Aplite is Veined or Pebbled and that of Phonolite is Banded and Foilated. Properties of rock is another aspect for Aplite vs Phonolite. The hardness of Aplite is 6.5 and that of Phonolite is 5.5-6. The types of Aplite are Not Available whereas types of Phonolite are Kenyte. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite and Phonolite is white. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Phonolite is Not Available. 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 Phonolite is heat resistant, impact resistant, wear resistant.
