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.
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.

Benmoreite vs Scoria Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Benmoreite vs Scoria characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Benmoreite and Properties of Scoria. Learn more about Benmoreite vs Scoria in the next section. The interior uses of Benmoreite include Floor tiles, Homes, Hotels and Kitchens whereas the interior uses of Scoria include Decorative aggregates and Interior decoration. Due to some exceptional properties of Benmoreite and Scoria, they have various applications in construction industry. The uses of Benmoreite in construction industry include As dimension stone, Cobblestones, Rail track ballast, Roadstone and that of Scoria include Cement manufacture, Construction aggregate, For road aggregate, In landscaping and drainage works.
More about Benmoreite and Scoria
Here you can know more about Benmoreite and Scoria. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Benmoreite and Scoria 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 Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica. You can also check out the list of all Igneous Rocks. When we have to compare Benmoreite vs Scoria, 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, Scoria is available in black, brown, dark grey to black, red colors. Appearance of Benmoreite is Rough and Dull and that of Scoria is Glassy and Vesicular. Properties of rock is another aspect for Benmoreite vs Scoria. The hardness of Benmoreite is 6 and that of Scoria is 5-6. The types of Benmoreite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB) and Tholeiitic Basalt whereas types of Scoria 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 Scoria is white. The specific heat capacity of Benmoreite is 0.84 kJ/Kg K and that of Scoria 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 Scoria is heat resistant, impact resistant, pressure resistant, wear resistant.
