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.
Eclogite forms from high-pressure metamorphism of mafic igneous rocks mainly, basalt or gabbro as it plunges into the mantle in a subduction zone.

More about Benmoreite and Eclogite
Here you can know more about Benmoreite and Eclogite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Benmoreite and Eclogite 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 Eclogite includes Amphibole, Coesite, Corundum, Dolomite, Garnet, Kyanite, Lawsonite, Paragonite, Phengite, Pyroxene, Quartz, Rutile, Zoisite. You can also check out the list of all . When we have to compare Benmoreite vs Eclogite, 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, Eclogite is available in black, brown, colourless, green, grey, pink, white colors. Appearance of Benmoreite is Rough and Dull and that of Eclogite is Dull, Banded and Foilated. Properties of rock is another aspect for Benmoreite vs Eclogite. The hardness of Benmoreite is 6 and that of Eclogite is 3.5-4. The types of Benmoreite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB) and Tholeiitic Basalt whereas types of Eclogite are Not Available. 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 Eclogite is white. The specific heat capacity of Benmoreite is 0.84 kJ/Kg K and that of Eclogite is Not Available. 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 Eclogite is heat resistant.
