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.
Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Jadeitite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.

More about Taconite and Jadeitite
Here you can know more about Taconite and Jadeitite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Jadeitite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Jadeitite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Jadeitite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Jadeitite is available in black, brown, green, grey, white colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Jadeitite is Rough and Dull. Properties of rock is another aspect for Taconite vs Jadeitite. The hardness of Taconite is 5.5-6 and that of Jadeitite is 3-5. The types of Taconite are Iron formation whereas types of Jadeitite are Metamorphic rock. 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 Jadeitite is white, greenish white or grey. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Jadeitite is 0.95 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 Jadeitite is heat resistant, water resistant.
