Formation

Formation
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.   
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.

Peridotite vs Aplite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Peridotite and Aplite Reserves. Peridotite is a dense, coarse-grained plutonic is the main constituent of the earth's mantle. Aplite is a fine-grained granite composed mainly of feldspar and quartz. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Peridotite vs Aplite information and Peridotite vs Aplite characteristics in the upcoming sections.

Peridotite vs Aplite 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. Peridotite vs Aplite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Peridotite and Properties of Aplite. Learn more about Peridotite vs Aplite in the next section. The interior uses of Peridotite include Decorative aggregates and Interior decoration whereas the interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Peridotite and Aplite, they have various applications in construction industry. The uses of Peridotite in construction industry include As dimension stone, Cobblestones and that of Aplite include As dimension stone.

More about Peridotite and Aplite

Here you can know more about Peridotite and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Aplite consists of mineral content and compound content. The mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Aplite is available in black, grey, orange, pink, white colors. Appearance of Peridotite is Rough and Shiny and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Peridotite vs Aplite. The hardness of Peridotite is 5.5-6 and that of Aplite is 6.5. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite whereas types of Aplite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Peridotite and Aplite is white. The specific heat capacity of Peridotite is 1.26 kJ/Kg K and that of Aplite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Peridotite is heat resistant, pressure resistant, wear resistant whereas Aplite is heat resistant, wear resistant.
