Tuff vs Basaltic Trachyandesite


Basaltic Trachyandesite vs Tuff


Definition

Definition
Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption   
Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface   

History
  
  

Origin

Tuff vs Basaltic Trachyandesite 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 Basaltic Trachyandesite Reserves. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Basaltic Trachyandesite is an extrusive igneous rock which is a type of Basalt rock and is formed by the rapid cooling of basaltic lava exposed at or very near the Earth's surface. 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 Basaltic Trachyandesite information and Tuff vs Basaltic Trachyandesite characteristics in the upcoming sections.

More about Tuff and Basaltic Trachyandesite

Here you can know more about Tuff and Basaltic Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tuff and Basaltic Trachyandesite consists of mineral content and compound content. The mineral content of Tuff includes Calcite, Chlorite and mineral content of Basaltic Trachyandesite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Tuff vs Basaltic Trachyandesite, the texture, color and appearance plays an important role in determining the type of rock. Tuff is available in brown, grey, yellow colors whereas, Basaltic Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Tuff is Dull, Vesicular and Foilated and that of Basaltic Trachyandesite is Dull and Soft. Properties of rock is another aspect for Tuff vs Basaltic Trachyandesite. The hardness of Tuff is 4-6 and that of Basaltic Trachyandesite is 6. The types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite. whereas types of Basaltic Trachyandesite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. 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 Basaltic Trachyandesite is white to grey. The specific heat capacity of Tuff is 0.20 kJ/Kg K and that of Basaltic Trachyandesite is 0.84 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 Basaltic Trachyandesite is heat resistant, pressure resistant, wear resistant.
