Definition
Whiteschist is an uncommon rock type belonging to a class of metamorphic rock, this is formed at high-ultra-high pressures
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase

Formation
Whiteschist is formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.
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.

Whiteschist 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. Whiteschist vs Amphibolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Whiteschist and Properties of Amphibolite. Learn more about Whiteschist vs Amphibolite in the next section. The interior uses of Whiteschist include Decorative aggregates 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 Whiteschist and Amphibolite, they have various applications in construction industry. The uses of Whiteschist in construction industry include For road aggregate 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 Whiteschist and Amphibolite
Here you can know more about Whiteschist and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Whiteschist and Amphibolite consists of mineral content and compound content. The mineral content of Whiteschist includes Carbonate, Coesite, Quartz, Silica 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 Metamorphic Rocks. When we have to compare Whiteschist vs Amphibolite, the texture, color and appearance plays an important role in determining the type of rock. Whiteschist is available in colourless, green, grey, white colors whereas, Amphibolite is available in black, brown, green, grey colors. Appearance of Whiteschist is Banded and Foilated and that of Amphibolite is Foliated. Properties of rock is another aspect for Whiteschist vs Amphibolite. The hardness of Whiteschist is 1.5 and that of Amphibolite is 6-7. The types of Whiteschist 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 Whiteschist is white while that of Amphibolite is white to grey. The specific heat capacity of Whiteschist is 0.92 kJ/Kg K 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.Whiteschist is heat resistant whereas Amphibolite is heat resistant, pressure resistant, wear resistant.
