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.
Phyllite is a metamorphic rock which is formed by regional metamorphism of argillaceous sediments since their cleavage arose due to deviatoric stress.

More about Taconite and Phyllite
Here you can know more about Taconite and Phyllite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Phyllite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Phyllite includes Albite, Alusite, Amphibole, Apatite, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc, Zircon. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Phyllite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Phyllite is available in black to grey, light greenish grey colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Phyllite is Crinkled or Wavy. Properties of rock is another aspect for Taconite vs Phyllite.
