Archaeological Significance
Formation
Chalk is formed from lime mud, which accumulates on the sea floor which is then transformed into rock by geological processes.
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 Chalk and Monzonite
Here you can know more about Chalk and Monzonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Chalk and Monzonite consists of mineral content and compound content. The mineral content of Chalk includes Calcite, Clay, Clay Minerals, Quartz, Sand 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 Sedimentary Rocks. When we have to compare Chalk vs Monzonite, the texture, color and appearance plays an important role in determining the type of rock. Chalk is available in grey, white, yellow colors whereas, Monzonite is available in black, brown, light to dark grey, white colors. Appearance of Chalk is Soft and that of Monzonite is Shiny. Properties of rock is another aspect for Chalk vs Monzonite. The hardness of Chalk is 1 and that of Monzonite is 6-7. The types of Chalk are Chalk Marl and Marl 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 Chalk and Monzonite is white. The specific heat capacity of Chalk is 0.90 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.Chalk is heat resistant whereas Monzonite is heat resistant, impact resistant, pressure resistant.
