5.1 Formation
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.
Rhyolite is a felsic extrusive rock and due to its high silica content, rhyolite lava is very viscous and is volcanic equivalent of granite.

Tuff vs Rhyolite 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 Tuff and Rhyolite Reserves. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Rhyolite is a fine-grained igneous rock which is rich in silica. 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 Tuff vs Rhyolite information and Tuff vs Rhyolite characteristics in the upcoming sections.

Tuff vs Rhyolite 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. Tuff vs Rhyolite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Tuff and Properties of Rhyolite. Learn more about Tuff vs Rhyolite in the next section. The interior uses of Tuff include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Rhyolite include Decorative aggregates, Homes, Hotels, Interior decoration and Kitchens. Due to some exceptional properties of Tuff and Rhyolite, they have various applications in construction industry. The uses of Tuff in construction industry include Building houses or walls, Construction aggregate and that of Rhyolite include Arrowheads, As dimension stone, Building houses or walls, Construction aggregate, Cutting tool, For road aggregate, Knives.

More about Tuff and Rhyolite

Here you can know more about Tuff and Rhyolite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tuff and Rhyolite consists of mineral content and compound content. The mineral content of Tuff includes Calcite, Chlorite and mineral content of Rhyolite includes Biotite, Feldspar, Hornblade, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Tuff vs Rhyolite, the texture, color and appearance plays an important role in determining the type of rock. Tuff is available in brown, grey, yellow colors whereas, Rhyolite is available in grey, white, light black colors. Appearance of Tuff is Dull, Vesicular and Foilated and that of Rhyolite is Banded. Properties of rock is another aspect for Tuff vs Rhyolite. The hardness of Tuff is 4-6 and that of Rhyolite is 6-7. The types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite. whereas types of Rhyolite are Pumice Rocks, Obsidian Rocks, Perlite Rocks, Porphyritic Rocks.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tuff is white while that of Rhyolite is colorless. The specific heat capacity of Tuff is 0.20 kJ/Kg K and that of Rhyolite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Tuff is heat resistant, impact resistant, pressure resistant, wear resistant whereas Rhyolite is heat resistant, wear resistant.
