5 Formation

5.1 Formation

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Metapelite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

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.

Metapelite 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 Metapelite and Tuff Reserves. Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone. 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 Metapelite vs Tuff information and Metapelite vs Tuff characteristics in the upcoming sections.

More about Metapelite and Tuff

Here you can know more about Metapelite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Tuff consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Metapelite is Banded and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Metapelite vs Tuff. The hardness of Metapelite is 5-6 and that of Tuff is 4-6. The types of Metapelite 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 Metapelite is unknown while that of Tuff is white. The specific heat capacity of Metapelite is 0.72 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.Metapelite is heat resistant, impact resistant, pressure resistant whereas Tuff is heat resistant, impact resistant, pressure resistant, wear resistant.
