Archaeological Significance
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.
Taconite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. When the river reaches a lake or sea, its load of transported rocks settles or deposits at the bottom of sea or lake.

More about Larvikite and Taconite
Here you can know more about Larvikite and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Larvikite and Taconite 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 Taconite includes Hematite, Magnetite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Larvikite vs Taconite, 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, Taconite is available in red, reddish brown colors. Appearance of Larvikite is Shiny and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Larvikite vs Taconite. The hardness of Larvikite is 6-7 and that of Taconite is 5.5-6. The types of Larvikite are Quartz Monzonite, Syenite and Diorite whereas types of Taconite are Iron formation. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Larvikite and Taconite is white. The specific heat capacity of Larvikite is 0.92 kJ/Kg K and that of Taconite is 3.20 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 Taconite is heat resistant, impact resistant, pressure resistant, wear resistant.
