Definition
A hydration and metamorphic transformation of ultramafic rock from the Earth's mantle is called as serpentinization, a group of minerals is formed by serpentinization compose rock 'serpentinite'.
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica

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

Serpentinite vs Taconite Characteristics
Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Serpentinite vs Taconite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Serpentinite and Properties of Taconite. Learn more about Serpentinite vs Taconite in the next section. The interior uses of Serpentinite include Decorative aggregates and Interior decoration whereas the interior uses of Taconite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Serpentinite and Taconite, they have various applications in construction industry. The uses of Serpentinite in construction industry include As dimension stone, Cement manufacture, For road aggregate, Making natural cement and that of Taconite include As dimension stone, Used for flooring, stair treads, borders and window sills..
More about Serpentinite and Taconite
Here you can know more about Serpentinite and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Serpentinite and Taconite consists of mineral content and compound content. The mineral content of Serpentinite includes Carbonate, Magnetite, Pyrrhotite, Serpentine, Sulfides and mineral content of Taconite includes Hematite, Magnetite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Serpentinite vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Serpentinite is available in black, brown, colourless, green, grey, white colors whereas, Taconite is available in red, reddish brown colors. Appearance of Serpentinite is Rough and Dull and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Serpentinite vs Taconite. The hardness of Serpentinite is 3-5 and that of Taconite is 5.5-6. The types of Serpentinite are Jadeitite whereas types of Taconite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Serpentinite and Taconite is white, greenish white or grey. The specific heat capacity of Serpentinite is 0.95 kJ/Kg K and that of Taconite is 3.20 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Serpentinite is heat resistant whereas Taconite is heat resistant, impact resistant, pressure resistant, wear resistant.
