Formation
Mangerite 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.
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.

Mangerite vs Picrite 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. Mangerite vs Picrite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Mangerite and Properties of Picrite. Learn more about Mangerite vs Picrite in the next section. The interior uses of Mangerite include Decorative aggregates and Interior decoration whereas the interior uses of Picrite include Countertops, Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Mangerite and Picrite, they have various applications in construction industry. The uses of Mangerite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate and that of Picrite include As a sintering agent in steel industry to process iron ore, Cement manufacture, For road aggregate, Manufacture of magnesium and dolomite refractories, Roadstone, Used for flooring, stair treads, borders and window sills..
More about Mangerite and Picrite
Here you can know more about Mangerite and Picrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Mangerite and Picrite consists of mineral content and compound content. The mineral content of Mangerite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite. You can also check out the list of all Igneous Rocks. When we have to compare Mangerite vs Picrite, the texture, color and appearance plays an important role in determining the type of rock. Mangerite is available in black, brown, light to dark grey, white colors whereas, Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors. Appearance of Mangerite is Shiny and that of Picrite is Rough and Shiny. Properties of rock is another aspect for Mangerite vs Picrite. The hardness of Mangerite is 6-7 and that of Picrite is 6.8. The types of Mangerite are Not Available whereas types of Picrite are Oceanite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Mangerite is white while that of Picrite is white, greenish white or grey. The specific heat capacity of Mangerite is 0.92 kJ/Kg K and that of Picrite is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Mangerite is heat resistant, impact resistant, pressure resistant whereas Picrite is heat resistant.
