Formation
Hornblendite 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.
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 Hornblendite and Benmoreite
Here you can know more about Hornblendite and Benmoreite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Hornblendite and Benmoreite consists of mineral content and compound content. The mineral content of Hornblendite includes Amphibole, Calcite, Hornblade, Magnetite, Plagioclase, Wollastonite 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 Hornblendite vs Benmoreite, the texture, color and appearance plays an important role in determining the type of rock. Hornblendite is available in black, brown, green, grey colors whereas, Benmoreite is available in black, brown, light to dark grey colors. Appearance of Hornblendite is Foliated and that of Benmoreite is Rough and Dull. Properties of rock is another aspect for Hornblendite vs Benmoreite. The hardness of Hornblendite is 6-7 and that of Benmoreite is 6. The types of Hornblendite are Hornblende Gabbro and Hornblende Peridotite 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 Hornblendite is white to grey while that of Benmoreite is black. The specific heat capacity of Hornblendite 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.Hornblendite is heat resistant, pressure resistant, wear resistant whereas Benmoreite is heat resistant, pressure resistant, wear resistant.
