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.
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.

Aplite vs Peridotite 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 Peridotite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Aplite and Properties of Peridotite. Learn more about Aplite vs Peridotite 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 Peridotite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Aplite and Peridotite, they have various applications in construction industry. The uses of Aplite in construction industry include As dimension stone and that of Peridotite include As dimension stone, Cobblestones.
More about Aplite and Peridotite
Here you can know more about Aplite and Peridotite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Aplite and Peridotite 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 Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Aplite vs Peridotite, 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, Peridotite is available in dark greenish - grey colors. Appearance of Aplite is Veined or Pebbled and that of Peridotite is Rough and Shiny. Properties of rock is another aspect for Aplite vs Peridotite. The hardness of Aplite is 6.5 and that of Peridotite is 5.5-6. The types of Aplite are Not Available whereas types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Aplite and Peridotite is white. The specific heat capacity of Aplite is 0.79 kJ/Kg K and that of Peridotite is 1.26 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 Peridotite is heat resistant, pressure resistant, wear resistant.
