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