Formation
The formation of Appinite takes place deep beneath the Earth’s surface at around 150 to 450 kms, and are erupted rapidly and violently.
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.

More about Appinite and Benmoreite
Here you can know more about Appinite and Benmoreite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Appinite and Benmoreite consists of mineral content and compound content. The mineral content of Appinite includes Amphibole, Carbonate, Garnet, Micas, Olivine, Phlogopite, Pyroxene and mineral content of Benmoreite 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 Appinite vs Benmoreite, the texture, color and appearance plays an important role in determining the type of rock. Appinite is available in black, bluish - grey, brown, dark greenish - grey, green, grey colors whereas, Benmoreite is available in black, brown, light to dark grey colors. Appearance of Appinite is Dull, Banded and Foilated and that of Benmoreite is Rough and Dull. Properties of rock is another aspect for Appinite vs Benmoreite. The hardness of Appinite is 5-6 and that of Benmoreite is 6. The types of Appinite are Not Available whereas types of Benmoreite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB) and Tholeiitic Basalt. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Appinite is white while that of Benmoreite is black. The specific heat capacity of Appinite is Not Available and that of Benmoreite 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.Appinite is heat resistant, impact resistant whereas Benmoreite is heat resistant, pressure resistant, wear resistant.
