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.
Andesite is a fine-grained igneous rock that forms when the magma is erupted onto the surface and is crystallized quickly.

Benmoreite vs Andesite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Benmoreite vs Andesite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Benmoreite and Properties of Andesite. Learn more about Benmoreite vs Andesite in the next section. The interior uses of Benmoreite include Floor tiles, Homes, Hotels and Kitchens whereas the interior uses of Andesite include Decorative aggregates, Floor tiles, Homes, Interior decoration and Kitchens. Due to some exceptional properties of Benmoreite and Andesite, they have various applications in construction industry. The uses of Benmoreite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Andesite include Cobblestones, Construction aggregate, For road aggregate.
More about Benmoreite and Andesite
Here you can know more about Benmoreite and Andesite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Benmoreite and Andesite 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 Andesite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite, Magnetite, Plagioclase, Pyroxene, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Benmoreite vs Andesite, 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, Andesite is available in bluish - grey, grey, pink, yellow colors. Appearance of Benmoreite is Rough and Dull and that of Andesite is Dull and Soft. Properties of rock is another aspect for Benmoreite vs Andesite. The hardness of Benmoreite is 6 and that of Andesite is 7. The types of Benmoreite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB) and Tholeiitic Basalt whereas types of Andesite are Icelandite. 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 Andesite is white. The specific heat capacity of Benmoreite is 0.84 kJ/Kg K and that of Andesite is 2.39 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 Andesite is heat resistant, pressure resistant, wear resistant.
