1 Definition
1.1 Definition
Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic 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

5.1 Formation
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.
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.

Pegmatite 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 Pegmatite and Felsite Reserves. Pegmatite rock is a holocrystalline, intrusive igneous rock which is composed of interlocking phaneritic 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 Pegmatite vs Felsite information and Pegmatite vs Felsite characteristics in the upcoming sections.

Pegmatite 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. Pegmatite vs Felsite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Pegmatite and Properties of Felsite. Learn more about Pegmatite vs Felsite in the next section. The interior uses of Pegmatite 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 Pegmatite and Felsite, they have various applications in construction industry. The uses of Pegmatite in construction industry include As dimension stone, Building houses or walls, Construction aggregate, For road aggregate, Landscaping and that of Felsite include Arrowheads, Cutting tool, Knives, Scrapers, Spear points.

More about Pegmatite and Felsite

Here you can know more about Pegmatite and Felsite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock.
