Archaeological Significance
Formation
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.
Monzonite 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.

More about Gabbro and Monzonite
Here you can know more about Gabbro and Monzonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Gabbro and Monzonite consists of mineral content and compound content. The mineral content of Gabbro includes Augite, Olivine, Plagioclase, Pyroxene and mineral content of Monzonite 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 Gabbro vs Monzonite, the texture, color and appearance plays an important role in determining the type of rock. Gabbro is available in dark grey to black colors whereas, Monzonite is available in black, brown, light to dark grey, white colors. Appearance of Gabbro is Veined and Shiny and that of Monzonite is Shiny. Properties of rock is another aspect for Gabbro vs Monzonite. The hardness of Gabbro is 7 and that of Monzonite is 6-7. The types of Gabbro are Anorthosite Gabbro and Norite Gabbro whereas types of Monzonite are Quartz Monzonite, Mangerite, Syenite and Diorite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Gabbro is black while that of Monzonite is white. The specific heat capacity of Gabbro is 0.71 kJ/Kg K and that of Monzonite 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.Gabbro is impact resistant, pressure resistant, wear resistant whereas Monzonite is heat resistant, impact resistant, pressure resistant.
