Formation
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 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 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. Turbidite vs Tuff characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Turbidite and Properties of Tuff. Learn more about Turbidite vs Tuff in the next section. The interior uses of Turbidite include Bathrooms, Countertops, Decorative aggregates, Flooring, Homes and Interior decoration whereas the interior uses of Tuff include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Turbidite and Tuff, they have various applications in construction industry. The uses of Turbidite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Making natural cement and that of Tuff include Building houses or walls, Construction aggregate.
More about Turbidite and Tuff
Here you can know more about Turbidite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Turbidite and Tuff consists of mineral content and compound content. The mineral content of Turbidite includes Coesite, Quartz, Sand and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Sedimentary Rocks. When we have to compare Turbidite vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Turbidite is available in black, brown, colourless, green, grey, pink colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Turbidite is Dull and Banded and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Turbidite vs Tuff. The hardness of Turbidite is 3 and that of Tuff is 4-6. The types of Turbidite 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 Turbidite and Tuff is white, greenish white or grey. The specific heat capacity of Turbidite 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.Turbidite is heat resistant whereas Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
