Definition
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica
Norite is a mafic intrusive igneous rock composed largely of the calcium-rich plagioclase labradorite, orthopyroxene, and olivine

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.
Norite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

More about Taconite and Norite
Here you can know more about Taconite and Norite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Norite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Norite includes Augite, Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Norite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Norite is available in dark grey to black colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Norite is Veined and Shiny. Properties of rock is another aspect for Taconite vs Norite. The hardness of Taconite is 5.5-6 and that of Norite is 7. The types of Taconite are Not Available whereas types of Norite 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 Norite is black. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Norite is Not Available. 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 Norite is impact resistant, pressure resistant, wear resistant.
