Definition
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica
Metapelite is an old and currently not widely used field geological term for a clay rich fine-grained clastic sediment or sedimentary rock, i.e. mud or a mudstone

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

Taconite vs Metapelite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Taconite vs Metapelite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Taconite and Properties of Metapelite. Learn more about Taconite vs Metapelite in the next section. The interior uses of Taconite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Metapelite include Decorative aggregates and Interior decoration. Due to some exceptional properties of Taconite and Metapelite, they have various applications in construction industry. The uses of Taconite in construction industry include As dimension stone, Used for flooring, stair treads, borders and window sills. and that of Metapelite include Cement manufacture, Construction aggregate, For road aggregate.
More about Taconite and Metapelite
Here you can know more about Taconite and Metapelite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Metapelite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Metapelite includes Albite, Chlorite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Metapelite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Metapelite is Banded. Properties of rock is another aspect for Taconite vs Metapelite. The hardness of Taconite is 5.5-6 and that of Metapelite is 5-6. The types of Taconite are Not Available whereas types of Metapelite are Not Available. 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 Metapelite is unknown. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Metapelite is 0.72 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 Metapelite is heat resistant, impact resistant, pressure resistant.
