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.

Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

Tuff vs Aplite 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 Aplite Reserves. Tuff is a type of rock made of volcanic ash ejected from a vent during a volcanic eruption. Aplite is a fine-grained granite composed mainly of feldspar and quartz. 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 Aplite information and Tuff vs Aplite characteristics in the upcoming sections.

More about Tuff and Aplite

Here you can know more about Tuff and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Tuff and Aplite consists of mineral content and compound content. The mineral content of Tuff includes Calcite, Chlorite and mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Tuff vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Tuff is available in brown, grey, yellow colors whereas, Aplite is available in black, grey, orange, pink, white colors. Appearance of Tuff is Dull, Vesicular and Foilated and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Tuff vs Aplite. The hardness of Tuff is 4-6 and that of Aplite is 6.5. The types of Tuff are Welded tuff, Rhyolitic tuff, Basaltic tuff, Trachyte tuff, Andesitic tuff and Ignimbrite. whereas types of Aplite are Igneous rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Tuff and Aplite is white. The specific heat capacity of Tuff is 0.20 kJ/Kg K and that of Aplite is 0.79 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 Aplite is heat resistant, wear resistant.
