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.
Pegmatite rock is holocrystalline, intrusive igneous rock which is formed by partial melting and dewatering during the process of metamorphism.

Benmoreite vs Pegmatite 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 Pegmatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Benmoreite and Properties of Pegmatite. Learn more about Benmoreite vs Pegmatite in the next section. The interior uses of Benmoreite include Floor tiles, Homes, Hotels and Kitchens whereas the interior uses of Pegmatite include Decorative aggregates, Flooring and Interior decoration. Due to some exceptional properties of Benmoreite and Pegmatite, 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 Pegmatite include As dimension stone, Building houses or walls, Construction aggregate, For road aggregate, Landscaping.
More about Benmoreite and Pegmatite
Here you can know more about Benmoreite and Pegmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Benmoreite and Pegmatite 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 Pegmatite includes Apatite, Beryl, Feldspar, Fluorite, Garnet, Lepidolite, Quartz, Silica, Spodumene, Topaz. You can also check out the list of all Igneous Rocks. When we have to compare Benmoreite vs Pegmatite, 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, Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors. Appearance of Benmoreite is Rough and Dull and that of Pegmatite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Benmoreite vs Pegmatite. The hardness of Benmoreite is 6 and that of Pegmatite is 7. The types of Benmoreite are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB) and Tholeiitic Basalt whereas types of Pegmatite are Granite Pegmatite, Gabbro Pegmatite and Diorite Pegmatite. 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 Pegmatite is white. The specific heat capacity of Benmoreite is 0.84 kJ/Kg K and that of Pegmatite 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 Pegmatite is heat resistant, impact resistant, pressure resistant.
