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

More about Monzonite and Pegmatite
Here you can know more about Monzonite and Pegmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Monzonite and Pegmatite consists of mineral content and compound content. The mineral content of Monzonite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon 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 Monzonite vs Pegmatite, the texture, color and appearance plays an important role in determining the type of rock. Monzonite is available in black, brown, light to dark grey, white colors whereas, Pegmatite is available in black, brown, cream, green, grey, pink, red, rust, silver, white, yellow colors. Appearance of Monzonite is Shiny and that of Pegmatite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Monzonite vs Pegmatite. The hardness of Monzonite is 6-7 and that of Pegmatite is 7. The types of Monzonite are Quartz Monzonite, Mangerite, Syenite and Diorite 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 Monzonite and Pegmatite is white. The specific heat capacity of Monzonite is 0.92 kJ/Kg K and that of Pegmatite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Monzonite is heat resistant, impact resistant, pressure resistant whereas Pegmatite is heat resistant, impact resistant, pressure resistant.
