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.
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.

Felsite vs Turbidite 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 Turbidite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Felsite and Properties of Turbidite. Learn more about Felsite vs Turbidite in the next section. The interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration. Due to some exceptional properties of Felsite and Turbidite, 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 Turbidite include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement.
More about Felsite and Turbidite
Here you can know more about Felsite and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Felsite and Turbidite consists of mineral content and compound content. The mineral content of Felsite includes Feldspar, Iron Oxides and mineral content of Turbidite includes Coesite, Quartz, Sand. You can also check out the list of all Igneous Rocks. When we have to compare Felsite vs Turbidite, 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, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Felsite vs Turbidite. The hardness of Felsite is 5-5.5 and that of Turbidite is 3. The types of Felsite are Not Available whereas types of Turbidite are Not Available. 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 Turbidite is white, greenish white or grey. The specific heat capacity of Felsite is 0.92 kJ/Kg K and that of Turbidite 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 Turbidite is heat resistant.
