Formation
Monzogranite 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.

The uses of Monzogranite in construction industry include As dimension stone 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 Monzogranite and Picrite
Here you can know more about Monzogranite and Picrite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Monzogranite and Picrite consists of mineral content and compound content. The mineral content of Monzogranite includes Apatite, Biotite, Hornblende, Microcline, Perthite, Plagioclase, Quartz, 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 Monzogranite vs Picrite, the texture, color and appearance plays an important role in determining the type of rock. Monzogranite is available in black, grey, orange, pink, white colors whereas, Picrite is available in black, brown, green, grey, pink, white, yellow colors. Appearance of Monzogranite is Veined or Pebbled and that of Picrite is Rough and Shiny. Properties of rock is another aspect for Monzogranite vs Picrite. The hardness of Monzogranite is 6-7 and that of Picrite is 6.8. The types of Monzogranite are Muscovite-Biotite-Metagranite, Muscovite-Metagranite, Schollen-Metagranite and Biotite-Metagranite 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 Monzogranite is white while that of Picrite is white, greenish white or grey. The specific heat capacity of Monzogranite is 0.79 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.Monzogranite is heat resistant, wear resistant whereas Picrite is heat resistant.
