Definition
Monzogranite is a type of igneous rock and belongs to biotite granite rocks that are considered to be the final fractionation product of magma
Hornfels is a metamorphic rock formed by the contact between mudstone or other clay rich rock, and a hot igneous body, and represents a heat altered equivalent of the original rock

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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Hornfels is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Monzogranite and Hornfels
Here you can know more about Monzogranite and Hornfels. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Monzogranite and Hornfels 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 Hornfels includes Andalusite. You can also check out the list of all Igneous Rocks. When we have to compare Monzogranite vs Hornfels, 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, Hornfels is available in brown, dark greenish - grey, green, reddish brown colors. Appearance of Monzogranite is Veined or Pebbled and that of Hornfels is Dull. Properties of rock is another aspect for Monzogranite vs Hornfels. The hardness of Monzogranite is 6-7 and that of Hornfels is 2-3. The types of Monzogranite are Muscovite-Biotite-Metagranite, Muscovite-Metagranite, Schollen-Metagranite and Biotite-Metagranite whereas types of Hornfels are Biotite hornfels. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Monzogranite is white while that of Hornfels is . The specific heat capacity of Monzogranite is 0.79 kJ/Kg K and that of Hornfels is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Monzogranite is heat resistant, wear resistant whereas Hornfels is heat resistant, impact resistant, pressure resistant.
