Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Amphibolite can be defined as a granular metamorphic rock which mainly consist of hornblende and plagioclase

Formation
Wehrlite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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.

Wehrlite 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. Wehrlite vs Amphibolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Amphibolite. Learn more about Wehrlite vs Amphibolite in the next section. The interior uses of Wehrlite 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 Wehrlite and Amphibolite, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones 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 Wehrlite and Amphibolite
Here you can know more about Wehrlite and Amphibolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Amphibolite consists of mineral content and compound content. The mineral content of Wehrlite includes 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 Wehrlite vs Amphibolite, the texture, color and appearance plays an important role in determining the type of rock. Wehrlite is available in dark greenish - grey, green colors whereas, Amphibolite is available in black, brown, green, grey colors. Appearance of Wehrlite is Rough and Banded and that of Amphibolite is Foliated. Properties of rock is another aspect for Wehrlite vs Amphibolite. The hardness of Wehrlite is 5.5-6 and that of Amphibolite is 6-7. The types of Wehrlite 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 Wehrlite is white while that of Amphibolite is white to grey. The specific heat capacity of Wehrlite is 0.63 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.Wehrlite is heat resistant, impact resistant, pressure resistant whereas Amphibolite is heat resistant, pressure resistant, wear resistant.
