5.1 Formation

Picrite 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.

Picrite vs Benmoreite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Picrite and Benmoreite Reserves. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. An iron rich extrusive rock found as a member of the alkali basalt magma series. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Picrite vs Benmoreite information and Picrite vs Benmoreite characteristics in the upcoming sections.

More about Picrite and Benmoreite

Here you can know more about Picrite and Benmoreite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Picrite and Benmoreite consists of mineral content and compound content. The mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite 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 Picrite vs Benmoreite, the texture, color and appearance plays an important role in determining the type of rock. Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors whereas, Benmoreite is available in black, brown, light to dark grey colors. Appearance of Picrite is Rough and Shiny and that of Benmoreite is Rough and Dull. Properties of rock is another aspect for Picrite vs Benmoreite. The hardness of Picrite is 6.8 and that of Benmoreite is 6. The types of Picrite are Oceanite 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 Picrite is white, greenish white or grey while that of Benmoreite is black. The specific heat capacity of Picrite is 0.88 kJ/Kg K 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.Picrite is heat resistant whereas Benmoreite is heat resistant, pressure resistant, wear resistant.
