1.1 Definition

Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption

Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix

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.

Cataclasiste rocks mainly form by pressure deep under the Earth's surface, from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

Tuff vs Cataclasite 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 Cataclasite Reserves. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Cataclasite is a type of cataclastic rock that is formed by fracturing and comminution during faulting. It is normally cohesive and non-foliated, consisting of angular clasts in a finer-grained matrix. 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.

More about Tuff and Cataclasite

Here you can know more about Tuff and Cataclasite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tuff and Cataclasite consists of mineral content and compound content. The mineral content of Tuff includes Calcite, Chlorite and mineral content of Cataclasite includes Albite, Apatite, Augite, Biotite, Calcite, Enstatite, Epidote, Feldspar, Micas, Muscovite or Illite, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Tuff vs Cataclasite, the texture, color and appearance plays an important role in determining the type of rock. Tuff is available in brown, grey, yellow colors whereas, Cataclasite is available in brown, green, white, yellow colors. Appearance of Tuff is Dull, Vesicular and Foilated and that of Cataclasite is Dull and Banded. Properties of rock is another aspect for Tuff vs Cataclasite. The hardness of Tuff is 4-6 and that of Cataclasite is 3-4. The types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite. whereas types of Cataclasite are Protocataclasite, Mesocataclasite, Ultracataclasite and Foliated cataclasite. 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 Cataclasite is black. The specific heat capacity of Tuff is 0.20 kJ/Kg K and that of Cataclasite 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 Cataclasite is heat resistant, impact resistant, pressure resistant.
