Definition
Ignimbrite is a volcanic rock consisting mainly of pumice fragments, formed by the consolidation of material deposited by pyroclastic flows
Monzonite is a granular igneous rock with composition between syenite and diorite and containing approximately equal amounts of orthoclase and plagioclase

Formation
Ignimbrites are formed from very poorly sorted mixture of volcanic ash or tuff and pumice lapilli, commonly with scattered lithic fragments.
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 Ignimbrite and Monzonite
Here you can know more about Ignimbrite and Monzonite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Ignimbrite and Monzonite consists of mineral content and compound content. The mineral content of Ignimbrite includes Apatite, Biotite, Calcite, Chlorite, Feldspar, Hematite, Hornblade, Ilmenite, Magnetite, Olivine, Pyroxene, Quartz 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 Igneous Rocks. When we have to compare Ignimbrite vs Monzonite, the texture, color and appearance plays an important role in determining the type of rock. Ignimbrite is available in beige, black, brown, grey, pink, white colors whereas, Monzonite is available in black, brown, light to dark grey, white colors. Appearance of Ignimbrite is Dull, Vesicular and Foilated and that of Monzonite is Shiny. Properties of rock is another aspect for Ignimbrite vs Monzonite. The hardness of Ignimbrite is 4-6 and that of Monzonite is 6-7. The types of Ignimbrite are Not Available 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 Ignimbrite and Monzonite is white. The specific heat capacity of Ignimbrite is 0.20 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.Ignimbrite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Monzonite is heat resistant, impact resistant, pressure resistant.
