Archaeological Significance
Formation
Laterite is a type of sedimentary rock which is generally a reddish weathering product of basalt.
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 Laterite and Taconite
Here you can know more about Laterite and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Laterite and Taconite consists of mineral content and compound content. The mineral content of Laterite includes Aluminum Oxides, Biotite, Hematite, Hornblade, Iron Oxides, Manganese Oxides, Micas, Muscovite or Illite, Plagioclase, Pyroxene and mineral content of Taconite includes Hematite, Magnetite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Laterite vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Laterite is available in brown, buff, red colors whereas, Taconite is available in red, reddish brown colors. Appearance of Laterite is Rough and Banded and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Laterite vs Taconite. The hardness of Laterite is 2 and that of Taconite is 5.5-6. The types of Laterite are Laterite 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 Laterite and Taconite is white. The specific heat capacity of Laterite is 0.92 kJ/Kg K and that of Taconite is 3.20 kJ/Kg K.
