5 Formation
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.
Tuff is formed when large masses of ash and sand which are mixed with hot gases are ejected by a volcano and avalanche rapidly down its slopes.

Felsite vs Tuff 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 Tuff 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. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. 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 Tuff information and Felsite vs Tuff characteristics in the upcoming sections.

Felsite vs Tuff 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 Tuff characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Felsite and Properties of Tuff. Learn more about Felsite vs Tuff in the next section. The interior uses of Felsite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Tuff include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Felsite and Tuff, 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 Tuff include Building houses or walls, Construction aggregate.

More about Felsite and Tuff

Here you can know more about Felsite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Felsite and Tuff consists of mineral content and compound content. The mineral content of Felsite includes Feldspar, Iron Oxides and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Igneous Rocks. When we have to compare Felsite vs Tuff, 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, Tuff is available in brown, grey, yellow colors. Appearance of Felsite is Layered, Banded, Veined and Shiny and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Felsite vs Tuff. The hardness of Felsite is 5-5.5 and that of Tuff is 4-6. The types of Felsite are Not Available whereas types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Felsite and Tuff is white. The specific heat capacity of Felsite is 0.92 kJ/Kg K and that of Tuff is 0.20 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 Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
