Definition
Appinite is an igneous rock in which the crystals are so fine grained that individual minerals cannot be easily distinguished
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase

Formation
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
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.

Appinite vs Amphibolite 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. Appinite vs Amphibolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Appinite and Properties of Amphibolite. Learn more about Appinite vs Amphibolite in the next section. The interior uses of Appinite include Decorative aggregates, Homes and Interior decoration whereas the interior uses of Amphibolite include Countertops, Decorative aggregates, Entryways, Floor tiles, Flooring, Homes, Hotels and Kitchens. Due to some exceptional properties of Appinite and Amphibolite, they have various applications in construction industry. The uses of Appinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Amphibolite include As dimension stone, Building houses or walls, Cobblestones, Construction aggregate, For road aggregate, Landscaping, Production of glass and ceramics, Roadstone.
More about Appinite and Amphibolite
Here you can know more about Appinite and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Appinite and Amphibolite consists of mineral content and compound content. The mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Amphibolite includes Amphibole, Andalusite, Biotite, Calcite, Epidote, Garnet, Hornblade, Kyanite, Magnetite, Olivine, Plagioclase, Pyroxene, Staurolite, Wollastonite. You can also check out the list of all Igneous Rocks. When we have to compare Appinite vs Amphibolite, the texture, color and appearance plays an important role in determining the type of rock. Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Amphibolite is available in black, brown, green, grey colors. Appearance of Appinite is Dull, Banded and Foilated and that of Amphibolite is Foliated. Properties of rock is another aspect for Appinite vs Amphibolite. The hardness of Appinite is 5-6 and that of Amphibolite is 6-7. The types of Appinite are Not Available whereas types of Amphibolite are Hornblendite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Appinite is white while that of Amphibolite is white to grey. The specific heat capacity of Appinite is Not Available and that of Amphibolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Appinite is heat resistant, impact resistant whereas Amphibolite is heat resistant, pressure resistant, wear resistant.
