5 Formation

5.1 Formation

Trachyandesite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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.

More about Trachyandesite and Tuff

Here you can know more about Trachyandesite and Tuff. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Trachyandesite and Tuff consists of mineral content and compound content. The mineral content of Trachyandesite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase and mineral content of Tuff includes Calcite, Chlorite. You can also check out the list of all Igneous Rocks. When we have to compare Trachyandesite vs Tuff, the texture, color and appearance plays an important role in determining the type of rock. Trachyandesite is available in black, brown, light to dark grey colors whereas, Tuff is available in brown, grey, yellow colors. Appearance of Trachyandesite is Dull and Soft and that of Tuff is Dull, Vesicular and Foilated. Properties of rock is another aspect for Trachyandesite vs Tuff. The hardness of Trachyandesite is 4-5 and that of Tuff is 4-6. The types of Trachyandesite are Basaltic Trachyandesite 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 Trachyandesite is light to dark brown while that of Tuff is white. The specific heat capacity of Trachyandesite is 0.84 kJ/Kg K and that of Tuff is 0.20 kJ/Kg K.
