Formation
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.
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.

More about Dacite and Monzogranite
Here you can know more about Dacite and Monzogranite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Dacite and Monzogranite consists of mineral content and compound content. The mineral content of Dacite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Magnetite, Plagioclase, Pyroxene, Quartz, Zircon and mineral content of Monzogranite includes Apatite, Biotite, Hornblende, Microcline, Perthite, Plagioclase, Quartz, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Dacite vs Monzogranite, the texture, color and appearance plays an important role in determining the type of rock. Dacite is available in bluish - grey, brown, grey, light to dark grey colors whereas, Monzogranite is available in black, grey, orange, pink, white colors. Appearance of Dacite is Vesicular and that of Monzogranite is Veined or Pebbled. Properties of rock is another aspect for Dacite vs Monzogranite. The hardness of Dacite is 2-2.25 and that of Monzogranite is 6-7. The types of Dacite are Footwall Dacite, Hanging wall Dacite, Tuff and Biotite Dacite whereas types of Monzogranite are Muscovite-Biotite-Metagranite, Muscovite-Metagranite, Schollen-Metagranite and Biotite-Metagranite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Dacite and Monzogranite is white. The specific heat capacity of Dacite is 0.92 kJ/Kg K and that of Monzogranite is 0.79 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Dacite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Monzogranite is heat resistant, wear resistant.
