Formation
Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
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 Diabase and Benmoreite
Here you can know more about Diabase and Benmoreite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Diabase and Benmoreite consists of mineral content and compound content. The mineral content of Diabase includes Augite, Chlorite, Olivine, Plagioclase, Pyroxene, Pyrrhotite, Serpentine 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 Diabase vs Benmoreite, the texture, color and appearance plays an important role in determining the type of rock. Diabase is available in dark grey to black colors whereas, Benmoreite is available in black, brown, light to dark grey colors. Appearance of Diabase is Vesicular and that of Benmoreite is Rough and Dull. Properties of rock is another aspect for Diabase vs Benmoreite. The hardness of Diabase is 7 and that of Benmoreite is 6. The types of Diabase 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 Diabase and Benmoreite is black. The specific heat capacity of Diabase 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.Diabase is heat resistant, impact resistant, pressure resistant, wear resistant whereas Benmoreite is heat resistant, pressure resistant, wear resistant.
