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.
Foidolites 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 Foidolite 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 Foidolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Foidolite. Learn more about Aplite vs Foidolite 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 Foidolite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Aplite and Foidolite, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Foidolite include As dimension stone, Cement manufacture, For road aggregate.
More about Aplite and Foidolite
Here you can know more about Aplite and Foidolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Foidolite 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 Foidolite includes Amphibole, Biotite, Feldspar, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Foidolite, 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, Foidolite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Aplite is Veined or Pebbled and that of Foidolite is Dull. Properties of rock is another aspect for Aplite vs Foidolite. The hardness of Aplite is 6.5 and that of Foidolite is 1.5. The types of Aplite are Not Available whereas types of Foidolite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite and Foidolite is white. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Foidolite 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 Foidolite is heat resistant, wear resistant.
