Formation
Benmoreite is a type of Igneous rock which is formed through the cooling and solidification of lava or magma. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
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.

More about Benmoreite and Trachyandesite
Here you can know more about Benmoreite and Trachyandesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Benmoreite and Trachyandesite consists of mineral content and compound content. The mineral content of Benmoreite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase and mineral content of Trachyandesite includes Alkali feldspar, Biotite, Olivine, Plagioclase, Pyroxene, Sodic plagioclase. You can also check out the list of all . When we have to compare Benmoreite vs Trachyandesite, the texture, color and appearance plays an important role in determining the type of rock. Benmoreite is available in black, brown, light to dark grey colors whereas, Trachyandesite is available in black, brown, light to dark grey colors. Appearance of Benmoreite is Rough and Dull and that of Trachyandesite is Dull and Soft. Properties of rock is another aspect for Benmoreite vs Trachyandesite. The hardness of Benmoreite is 6 and that of Trachyandesite is 4-5. The types of Benmoreite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB) and Tholeiitic Basalt 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 Benmoreite is black while that of Trachyandesite is light to dark brown. The specific heat capacity of Benmoreite 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.Benmoreite is heat resistant, pressure resistant, wear resistant whereas Trachyandesite is heat resistant, pressure resistant, wear resistant.
