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 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. Felsite vs Felsite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Felsite and Properties of Felsite. Learn more about Felsite vs Felsite in the next section. The interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Felsite and Felsite, 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 Felsite include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.
More about Felsite and Felsite
Here you can know more about Felsite and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Felsite and Felsite consists of mineral content and compound content. The mineral content of Felsite includes Feldspar, Iron Oxides 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 Felsite vs Felsite, 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, Felsite is available in black, blue, brown, green, orange, red, tan, yellow colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Felsite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Felsite vs Felsite. Hardness of Felsite and Felsite is 5-5.5. The types of Felsite 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 Felsite and Felsite is white. The specific heat capacity of Felsite is 0.92 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.Felsite is heat resistant, impact resistant whereas Felsite is heat resistant, impact resistant.
