Wehrlite vs Felsite


Definition

Definition
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   
Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites

Formation
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.

Felsite vs Wehrlite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Felsite and Wehrlite Reserves. 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. Wehrlite is an ultramafic and ultrabasic rock that is a mixture of olivine and clinopyroxene. It is a subdivision of the peridotites. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Felsite vs Wehrlite information and Felsite vs Wehrlite characteristics in the upcoming sections.

Felsite vs Wehrlite 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. Felsite vs Wehrlite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Felsite and Properties of Wehrlite. Learn more about Felsite vs Wehrlite in the next section. The interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Wehrlite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Felsite and Wehrlite, they have various applications in construction industry. The uses of Felsite in construction industry include Arrowheads, Cutting tool, Knives, Scrapers, Spear points and that of Wehrlite include As dimension stone, Cobblestones.

More about Felsite and Wehrlite

Here you can know more about Felsite and Wehrlite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Felsite and Wehrlite consists of mineral content and compound content. The mineral content of Felsite includes Feldspar, Iron Oxides and mineral content of Wehrlite includes Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Felsite vs Wehrlite, the texture, color and appearance plays an important role in determining the type of rock. Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors whereas, Wehrlite is available in dark greenish - grey, green colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Wehrlite is Rough and Banded. Properties of rock is another aspect for Felsite vs Wehrlite. The hardness of Felsite is 5-5.5 and that of Wehrlite is 5.5-6. The types of Felsite are Not Available whereas types of Wehrlite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Felsite and Wehrlite is white. The specific heat capacity of Felsite is 0.92 kJ/Kg K and that of Wehrlite is 0.63 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Felsite is heat resistant, impact resistant whereas Wehrlite is heat resistant, impact resistant, pressure resistant.
