Definition
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites
Felsite is a very fine grained volcanic rock that may or may not contain larger crystals and light colored rock that typically requires petrographic examination or chemical analysis for more precise definition

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.
Felsite 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.

Wehrlite vs Felsite 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 Felsite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Wehrlite and Properties of Felsite. Learn more about Wehrlite vs Felsite in the next section. The interior uses of Wehrlite include Decorative aggregates and Interior decoration whereas the interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Wehrlite and Felsite, they have various applications in construction industry. The uses of Wehrlite in construction industry include As dimension stone, Cobblestones and that of Felsite include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.
More about Wehrlite and Felsite
Here you can know more about Wehrlite and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Wehrlite and Felsite consists of mineral content and compound content. The mineral content of Wehrlite includes Pyroxene and mineral content of Felsite includes Feldspar, Iron Oxides. You can also check out the list of all Igneous Rocks. When we have to compare Wehrlite vs Felsite, 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, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Wehrlite is Rough and Banded and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Wehrlite vs Felsite. The hardness of Wehrlite is 5.5-6 and that of Felsite is 5-5.5. The types of Wehrlite are Not Available whereas types of Felsite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Wehrlite and Felsite is white. The specific heat capacity of Wehrlite is 0.63 kJ/Kg K and that of Felsite is 0.92 kJ/Kg K. 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 Felsite is heat resistant, impact resistant.
