Formation
Peridotites can be formed in two ways: as mantle rocks formed during the accretion and differentiation of the Earth or as cumulate rocks formed by precipitation of olivine and pyroxenes from basaltic magmas.
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.

More about Peridotite and Taconite
Here you can know more about Peridotite and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Peridotite and Taconite consists of mineral content and compound content. The mineral content of Peridotite includes Amphibole, Chromite, Garnet, Magnesium, Olivine, Phlogopite, Plagioclase, Pyroxene and mineral content of Taconite includes Hematite, Magnetite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Peridotite vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Peridotite is available in dark greenish - grey colors whereas, Taconite is available in red, reddish brown colors. Appearance of Peridotite is Rough and Shiny and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Peridotite vs Taconite. Hardness of Peridotite and Taconite is 5.5-6. The types of Peridotite are Dunite, Wehrlite, Harzburgite, Lherzolite and Pyrolite 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 Peridotite and Taconite is white. The specific heat capacity of Peridotite is 1.26 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.Peridotite is heat resistant, pressure resistant, wear resistant whereas Taconite is heat resistant, impact resistant, pressure resistant, wear resistant.
