Definition

Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.

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

Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

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.

Granulite vs Felsite 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 Granulite and Felsite Reserves. Granulite is fine to medium grained metamorphic rock with a granular of polygonal crystals.. 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. 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 Granulite vs Felsite information and Granulite vs Felsite characteristics in the upcoming sections.

More about Granulite and Felsite

Here you can know more about Granulite and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Granulite and Felsite consists of mineral content and compound content. The mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz and mineral content of Felsite includes Feldspar, Iron Oxides. You can also check out the list of all Metamorphic Rocks. When we have to compare Granulite vs Felsite, the texture, color and appearance plays an important role in determining the type of rock. Granulite is available in black, brown colors whereas, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Granulite is Veined or Pebbled and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Granulite vs Felsite. The hardness of Granulite is 6-7 and that of Felsite is 5-5.5. The types of Granulite are Metamorphic rock whereas types of Felsite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Granulite and Felsite is white. The specific heat capacity of Granulite is 0.14 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.Granulite is heat resistant, wear resistant whereas Felsite is heat resistant, impact resistant.
