Formation

Formation

Ijolite 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.

More about Ijolite and Trachyandesite

Here you can know more about Ijolite and Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ijolite and Trachyandesite consists of mineral content and compound content. The mineral content of Ijolite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite and mineral content of Trachyandesite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase. You can also check out the list of all Igneous Rocks. When we have to compare Ijolite vs Trachyandesite, the texture, color and appearance plays an important role in determining the type of rock. Ijolite is available in brown, buff, cream, green, grey, pink, white colors whereas, Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Ijolite is Banded and Foilated and that of Trachyandesite is Dull and Soft. Properties of rock is another aspect for Ijolite vs Trachyandesite. The hardness of Ijolite is 5.5-6 and that of Trachyandesite is 4-5. The types of Ijolite are Alkaline rock whereas types of Trachyandesite are Basaltic Trachyandesite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Ijolite is white while that of Trachyandesite is light to dark brown. The specific heat capacity of Ijolite is 0.84 kJ/Kg K and that of 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.Ijolite is heat resistant, impact resistant, wear resistant whereas Trachyandesite is heat resistant, pressure resistant, wear resistant.
