Definition
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica
Litchfieldite is a rare igneous rock which is coarse-grained, foliated and a variety of nepheline syenite, sometimes also called as nepheline syenite gneiss or gneissic nepeheline syenite

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.
Litchfieldite 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 Litchfieldite
Here you can know more about Taconite and Litchfieldite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Litchfieldite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Litchfieldite includes Albite, Amphibole, Biotite, Cancrinite, Feldspar, Hornblende, Plagioclase, Pyroxene, Sodalite. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Litchfieldite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Litchfieldite is available in brown, buff, cream, green, grey, pink, white colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Litchfieldite is Banded and Foilated. Properties of rock is another aspect for Taconite vs Litchfieldite. Hardness of Taconite and Litchfieldite is 5.5-6. The types of Taconite are Iron formation whereas types of Litchfieldite are Borolanite and Litchfieldite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Taconite and Litchfieldite is white. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Litchfieldite is 0.79 kJ/Kg K.
