Adakite vs Trachyandesite


Definition

Definition
Trachyandesite is an extrusive igneous rock.  
Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs

Formation

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.  
Adakite rocks are formed when the hydrous fluids are released from minerals that break down in metamorphosed basalt, and rise into the mantle they initiate partial melting.

Trachyandesite vs Adakite 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 Trachyandesite and Adakite Reserves. Trachyandesite is an extrusive igneous rock.. Adakite is an intermediate to felsic volcanic rock that has geochemical characteristics of magma which is said to be formed by partial melting of altered basalt that is subducted below volcanic arcs. 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 Trachyandesite vs Adakite information and Trachyandesite vs Adakite characteristics in the upcoming sections.

More about Trachyandesite and Adakite

Here you can know more about Trachyandesite and Adakite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Trachyandesite and Adakite 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 Adakite includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Igneous Rocks. When we have to compare Trachyandesite vs Adakite, 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, Adakite is available in black, brown, light to dark grey colors. Appearance of Trachyandesite is Dull and Soft and that of Adakite is Dull and Soft. Properties of rock is another aspect for Trachyandesite vs Adakite. The hardness of Trachyandesite is 4-5 and that of Adakite is 3-4. The types of Trachyandesite are Basaltic Trachyandesite whereas types of Adakite are Intermediate volcanic rock. 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 Adakite is bluish black. The specific heat capacity of Trachyandesite is 0.84 kJ/Kg K and that of Adakite 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.Trachyandesite is heat resistant, pressure resistant, wear resistant whereas Adakite is heat resistant, pressure resistant, wear resistant.
