Archaeological Significance
Formation
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.
Kenyte 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 Taconite and Kenyte
Here you can know more about Taconite and Kenyte. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Kenyte consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Kenyte includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Kenyte, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Kenyte is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Kenyte is Banded and Foilated. Properties of rock is another aspect for Taconite vs Kenyte. Hardness of Taconite and Kenyte is 5.5-6. The types of Taconite are Iron formation whereas types of Kenyte are Foidolite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Taconite is white while that of Kenyte is white, greenish white or grey. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Kenyte is 0.84 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Taconite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Kenyte is heat resistant, impact resistant, wear resistant.
