Formation

Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.

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.

Laterite 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 Laterite and Tuff Reserves. Laterite rock is a type of Sedimentary rock which is rich in iron and aluminium, formed in hot and wet tropical areas. 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 Laterite vs Tuff information and Laterite vs Tuff characteristics in the upcoming sections.

More about Laterite and Tuff

Here you can know more about Laterite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Tuff consists of mineral content and compound content. The mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Laterite is Rough and Banded and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Laterite vs Tuff. The hardness of Laterite is 2 and that of Tuff is 4-6. The types of Laterite are Laterite 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 Laterite and Tuff is white. The specific heat capacity of Laterite 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.Laterite is heat resistant, pressure resistant whereas Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
