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.
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

Monzonite vs Schist 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. Monzonite vs Schist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Monzonite and Properties of Schist. Learn more about Monzonite vs Schist in the next section. The interior uses of Monzonite include Decorative aggregates, Flooring and Interior decoration whereas the interior uses of Schist include Decorative aggregates, Floor tiles and Interior decoration. Due to some exceptional properties of Monzonite and Schist, they have various applications in construction industry. The uses of Monzonite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate and that of Schist include As dimension stone, Building houses or walls, Cement manufacture, For road aggregate, Roadstone.
More about Monzonite and Schist
Here you can know more about Monzonite and Schist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Monzonite and Schist 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 Schist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc. You can also check out the list of all Igneous Rocks. When we have to compare Monzonite vs Schist, 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, Schist is available in black, blue, brown, dark brown, green, grey, silver colors. Appearance of Monzonite is Shiny and that of Schist is Layered and Shiny. Properties of rock is another aspect for Monzonite vs Schist. The hardness of Monzonite is 6-7 and that of Schist is 3.5-4. The types of Monzonite are Quartz Monzonite, Mangerite, Syenite and Diorite whereas types of Schist are Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Monzonite and Schist is white. The specific heat capacity of Monzonite is 0.92 kJ/Kg K and that of Schist is 0.70 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 Schist is impact resistant, pressure resistant, water resistant.
