Archaeological Significance
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.
Chert forms when microcrystals of silicon dioxide grow within soft sediments that become limestone or chalk. The chert formation can be either of chemical or biological origin.

More about Monzogranite and Chert
Here you can know more about Monzogranite and Chert. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Monzogranite and Chert 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 Chert includes Quartz, Silicon. You can also check out the list of all Igneous Rocks. When we have to compare Monzogranite vs Chert, 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, Chert is available in black, brown, green, grey, red, white colors. Appearance of Monzogranite is Veined or Pebbled and that of Chert is Glassy or Pearly. Properties of rock is another aspect for Monzogranite vs Chert. The hardness of Monzogranite is 6-7 and that of Chert is 6.5-7. The types of Monzogranite are Muscovite-Biotite-Metagranite, Muscovite-Metagranite, Schollen-Metagranite and Biotite-Metagranite whereas types of Chert are Flint, Jasper, Radiolarite, Common Chert, Chalcedony, Agate, Onyx, Opal, Magadi-type Chert, Porcelanite, Siliceous Sinter. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Monzogranite and Chert is white. The specific heat capacity of Monzogranite is 0.79 kJ/Kg K and that of Chert is 0.74 kJ/Kg K.
