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.
Dacitic magma is formed by the subduction of young oceanic crust under a thick felsic continental plate. Further, the Oceanic crust is hydrothermally altered as quartz and sodium are added.

More about Monzogranite and Dacite
Here you can know more about Monzogranite and Dacite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Monzogranite and Dacite 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 Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Monzogranite vs Dacite, 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, Dacite is available in bluish - grey, brown, grey, light to dark grey colors. Appearance of Monzogranite is Veined or Pebbled and that of Dacite is Vesicular. Properties of rock is another aspect for Monzogranite vs Dacite. The hardness of Monzogranite is 6-7 and that of Dacite is 2-2.25. The types of Monzogranite are Muscovite-Biotite-Metagranite, Muscovite-Metagranite, Schollen-Metagranite and Biotite-Metagranite whereas types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Monzogranite and Dacite is white. The specific heat capacity of Monzogranite is 0.79 kJ/Kg K and that of Dacite 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.Monzogranite is heat resistant, wear resistant whereas Dacite is heat resistant, impact resistant, pressure resistant, wear resistant.
