Formation
Amphibolite is a coarse-grained metamorphic rock which forms by metamorphism of mafic igneous rocks like basalt and gabbro or from the metamorphism of clay-rich sedimentary rocks like marl or graywacke.
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.

Amphibolite 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. Amphibolite vs Aplite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Amphibolite and Properties of Aplite. Learn more about Amphibolite vs Aplite in the next section. The interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens 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 Amphibolite and Aplite, they have various applications in construction industry. The uses of Amphibolite in construction industry include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone and that of Aplite include As dimension stone.
More about Amphibolite and Aplite
Here you can know more about Amphibolite and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Amphibolite and Aplite consists of mineral content and compound content. The mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite 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 Amphibolite vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Amphibolite is available in black, brown, green, grey colors whereas, Aplite is available in black, grey, orange, pink, white colors. Appearance of Amphibolite is Foliated and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Amphibolite vs Aplite. The hardness of Amphibolite is 6-7 and that of Aplite is 6.5. The types of Amphibolite are Hornblendite 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 Amphibolite is white to grey while that of Aplite is white. The specific heat capacity of Amphibolite is Not Available 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.Amphibolite is heat resistant, pressure resistant, wear resistant whereas Aplite is heat resistant, wear resistant.
