Definition
Talc carbonate is nothing but a rock sequence or a mineral composition found in metamorphic ultramafic rocks.
Larvikite is an igneous rock and a variety of monzonite, notable for the presence of thumbnail-sized crystals of feldspar

Archaeological Significance
Formation
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Talc Carbonate is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
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.

More about Talc carbonate and Larvikite
Here you can know more about Talc carbonate and Larvikite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Talc carbonate and Larvikite consists of mineral content and compound content. The mineral content of Talc carbonate includes Carbonate, Chlorite, Magnesium and mineral content of Larvikite 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 Metamorphic Rocks. When we have to compare Talc carbonate vs Larvikite, the texture, color and appearance plays an important role in determining the type of rock. Talc carbonate is available in grey, white colors whereas, Larvikite is available in black, brown, light to dark grey, white colors. Appearance of Talc carbonate is Soft and that of Larvikite is Shiny. Properties of rock is another aspect for Talc carbonate vs Larvikite. The hardness of Talc carbonate is 1-2 and that of Larvikite is 6-7. The types of Talc carbonate are Sedimentary rock whereas types of Larvikite are Quartz Monzonite, Syenite and Diorite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Talc carbonate and Larvikite is white. The specific heat capacity of Talc carbonate is 0.92 kJ/Kg K and that of Larvikite 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.Talc carbonate is heat resistant, wear resistant whereas Larvikite is heat resistant, impact resistant, pressure resistant.
