Definition
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
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica

Formation
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 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 Metapelite and Taconite
Here you can know more about Metapelite and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Metapelite and Taconite consists of mineral content and compound content. The mineral content of Metapelite includes Albite, Chlorite, Quartz and mineral content of Taconite includes Hematite, Magnetite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Metapelite vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Metapelite is available in dark greenish - grey, green, light green, light greenish grey colors whereas, Taconite is available in red, reddish brown colors. Appearance of Metapelite is Banded and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Metapelite vs Taconite. The hardness of Metapelite is 5-6 and that of Taconite is 5.5-6. The types of Metapelite are Not Available whereas types of Taconite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Metapelite is unknown while that of Taconite is white. The specific heat capacity of Metapelite is 0.72 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.Metapelite is heat resistant, impact resistant, pressure resistant whereas Taconite is heat resistant, impact resistant, pressure resistant, wear resistant.
