1 Definition
1.1 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
Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone

5 Formation
5.1 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.
Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.

Felsite vs Quartzite 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 Quartzite 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. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. 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 Quartzite information and Felsite vs Quartzite characteristics in the upcoming sections.

Felsite vs Quartzite 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 Quartzite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Felsite and Properties of Quartzite. Learn more about Felsite vs Quartzite in the next section. The interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes. Due to some exceptional properties of Felsite and Quartzite, 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 Quartzite include Arrowheads, As dimension stone, Cement manufacture, Construction aggregate, Cutting tool, For road aggregate, Making natural cement, Production of glass and ceramics, Rail track ballast, Roadstone.

More about Felsite and Quartzite

Here you can know more about Felsite and Quartzite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Felsite and Quartzite consists of mineral content and compound content. The mineral content of Felsite includes Feldspar, Iron Oxides and mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Felsite vs Quartzite, 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, Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Quartzite is Lustrous. Properties of rock is another aspect for Felsite vs Quartzite. The hardness of Felsite is 5-5.5 and that of Quartzite is 6-7. The types of Felsite are Not Available whereas types of Quartzite 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 Quartzite is white. The specific heat capacity of Felsite is 0.92 kJ/Kg K and that of Quartzite is 0.75 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 Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant.
