Definition
Monzonite is a granular igneous rock with composition between syenite and diorite and containing approximately equal amounts of orthoclase and plagioclase
It is a metamorphic magnesium rich rock because it is composed of the mineral talc

Formation
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.
Soapstone is a talc-schist, which is a type of metamorphic rock and it is largely composed of the mineral talc and is thus rich inmagnesium.

More about Monzonite and Soapstone
Here you can know more about Monzonite and Soapstone. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Monzonite and Soapstone consists of mineral content and compound content. The mineral content of Monzonite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Soapstone includes Albite, Apatite, Biotite, Calcite, Carbonate, Clay Minerals, Hornblende, Ilmenite, Micas, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Monzonite vs Soapstone, the texture, color and appearance plays an important role in determining the type of rock. Monzonite is available in black, brown, light to dark grey, white colors whereas, Soapstone is available in black, black to grey, green, grey colors. Appearance of Monzonite is Shiny and that of Soapstone is Dull, Banded and Foilated. Properties of rock is another aspect for Monzonite vs Soapstone. The hardness of Monzonite is 6-7 and that of Soapstone is 1. The types of Monzonite are Quartz Monzonite, Mangerite, Syenite and Diorite whereas types of Soapstone are Metamorphic rock. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Monzonite is white while that of Soapstone is black. The specific heat capacity of Monzonite is 0.92 kJ/Kg K and that of Soapstone is 0.88 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Monzonite is heat resistant, impact resistant, pressure resistant whereas Soapstone is heat resistant, pressure resistant.
