Formation
Scoria forms when magma containing huge amount of dissolved gas flows from a volcano during an eruption.
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 Scoria and Benmoreite
Here you can know more about Scoria and Benmoreite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Scoria and Benmoreite consists of mineral content and compound content. The mineral content of Scoria includes Apatite, Biotite, Calcite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz, Silica 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 Scoria vs Benmoreite, the texture, color and appearance plays an important role in determining the type of rock. Scoria is available in black, brown, dark grey to black, red colors whereas, Benmoreite is available in black, brown, light to dark grey colors. Appearance of Scoria is Glassy and Vesicular and that of Benmoreite is Rough and Dull. Properties of rock is another aspect for Scoria vs Benmoreite. The hardness of Scoria is 5-6 and that of Benmoreite is 6. The types of Scoria 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 Scoria is white while that of Benmoreite is black.
