5 Formation

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.

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.

Tuff vs Turbidite 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 Turbidite Reserves. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles. 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 Turbidite information and Tuff vs Turbidite characteristics in the upcoming sections.

More about Tuff and Turbidite

Here you can know more about Tuff and Turbidite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tuff and Turbidite consists of mineral content and compound content. The mineral content of Tuff includes Calcite, Chlorite 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 Tuff vs Turbidite, the texture, color and appearance plays an important role in determining the type of rock. Tuff is available in brown, grey, yellow colors whereas, Turbidite is available in black, brown, colourless, green, grey, pink colors. Appearance of Tuff is Dull, Vesicular and Foilated and that of Turbidite is Dull and Banded. Properties of rock is another aspect for Tuff vs Turbidite. The hardness of Tuff is 4-6 and that of Turbidite is 3. The types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite. 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 Tuff is white while that of Turbidite is white, greenish white or grey. The specific heat capacity of Tuff is 0.20 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.Tuff is heat resistant, impact resistant, pressure resistant, wear resistant whereas Turbidite is heat resistant.
