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.

Phonolite are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.

Felsite vs Phonolite 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 Phonolite 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. Phonolite is an uncommon extrusive igneous rock volcanic rock of intermediate chemical composition between felsic and mafic. 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 Phonolite information and Felsite vs Phonolite characteristics in the upcoming sections.

More about Felsite and Phonolite

Here you can know more about Felsite and Phonolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Felsite and Phonolite consists of mineral content and compound content. The mineral content of Felsite includes Feldspar, Iron Oxides and mineral content of Phonolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Igneous Rocks. When we have to compare Felsite vs Phonolite, 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, Phonolite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Phonolite is Banded and Foilated. Properties of rock is another aspect for Felsite vs Phonolite. The hardness of Felsite is 5-5.5 and that of Phonolite is 5.5-6. The types of Felsite are Not Available whereas types of Phonolite are Kenyte.
