Definition
Larvikite is an igneous rock and a variety of monzonite, notable for the presence of thumbnail-sized crystals of feldspar
Trondhjemite is a leucocratic (light-colored) intrusive igneous rock. It is a variety of tonalite in which the plagioclase is mostly in the form of oligoclase. Trondhjemites are sometimes known as plagiogranites.

Formation
Larvikite 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.
When alkali feldspar is extracted from granite, it changes to granitoid and later, it becomes trondhjemite with quartz as major mineral.

More about Larvikite and Trondhjemite
Here you can know more about Larvikite and Trondhjemite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Larvikite and Trondhjemite consists of mineral content and compound content. The mineral content of Larvikite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Muscovite or Illite, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon and mineral content of Trondhjemite includes Albite, Amphibole, Apatite, Biotite, Feldspar, Hornblade, Ilmenite, Magnetite, Manganese Oxides, Olivine, Plagioclase, Pyroxene, Quartz, Sulfides, Titanite, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Larvikite vs Trondhjemite, the texture, color and appearance plays an important role in determining the type of rock. Larvikite is available in black, brown, light to dark grey, white colors whereas, Trondhjemite is available in black, brown, light to dark grey, white colors. Appearance of Larvikite is Shiny and that of Trondhjemite is Banded and Foilated. Properties of rock is another aspect for Larvikite vs Trondhjemite. Hardness of Larvikite and Trondhjemite is 6-7. The types of Larvikite are Quartz Monzonite, Syenite and Diorite whereas types of Trondhjemite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Larvikite is white while that of Trondhjemite is bluish black. The specific heat capacity of Larvikite is 0.92 kJ/Kg K and that of Trondhjemite 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.Larvikite is heat resistant, impact resistant, pressure resistant whereas Trondhjemite is heat resistant, pressure resistant, wear resistant.
