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

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.

More about Felsite and Pantellerite
Here you can know more about Felsite and Pantellerite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Felsite and Pantellerite consists of mineral content and compound content. The mineral content of Felsite includes Feldspar, Iron Oxides and mineral content of Pantellerite includes Amphibole, Feldspar, Ilmenite. You can also check out the list of all Igneous Rocks. When we have to compare Felsite vs Pantellerite, 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, Pantellerite is available in dark greenish - grey colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Pantellerite is Layered and Foliated. Properties of rock is another aspect for Felsite vs Pantellerite. The hardness of Felsite is 5-5.5 and that of Pantellerite is 6-7. The types of Felsite are Igneous rock whereas types of Pantellerite are Pantelleritic Ignimbrite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Felsite is white while that of Pantellerite is . The specific heat capacity of Felsite is 0.92 kJ/Kg K and that of Pantellerite is 0.84 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 Pantellerite is heat resistant.
