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.
Granulite is a fine-grained granular metamorphic rock in which the main component minerals are feldspars and quartz and forms at high temperature and pressure conditions.

More about Taconite and Granulite
Here you can know more about Taconite and Granulite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Granulite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Granulite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Quartz. You can also check out the list of all . When we have to compare Taconite vs Granulite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Granulite is available in black, brown colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Granulite is Veined or Pebbled. Properties of rock is another aspect for Taconite vs Granulite. The hardness of Taconite is 5.5-6 and that of Granulite is 6-7. The types of Taconite are Not Available whereas types of Granulite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Taconite and Granulite is white. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Granulite is 0.14 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 Granulite is heat resistant, wear resistant.
