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.
Schist formed by dynamic metamorphism at high temperatures and pressures that aligns the grains of mica, hornblende and other elongated minerals into thin layers.

Taconite vs Schist 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. Taconite vs Schist characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Taconite and Properties of Schist. Learn more about Taconite vs Schist in the next section. The interior uses of Taconite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Schist include Decorative aggregates, Floor tiles and Interior decoration. Due to some exceptional properties of Taconite and Schist, they have various applications in construction industry. The uses of Taconite in construction industry include As dimension stone, Used for flooring, stair treads, borders and window sills. and that of Schist include As dimension stone, Building houses or walls, Cement manufacture, For road aggregate, Roadstone.
More about Taconite and Schist
Here you can know more about Taconite and Schist. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Schist consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Schist includes Alusite, Amphibole, Biotite, Chlorite, Epidote, Feldspar, Garnet, Graphite, Hornblade, Kyanite, Micas, Muscovite or Illite, Porphyroblasts, Quartz, Sillimanite, Staurolite, Talc. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Schist, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Schist is available in black, blue, brown, dark brown, green, grey, silver colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Schist is Layered and Shiny. Properties of rock is another aspect for Taconite vs Schist. The hardness of Taconite is 5.5-6 and that of Schist is 3.5-4. The types of Taconite are Not Available whereas types of Schist are Mica Schists, Calc-Silicate Schists, Graphite Schists, Blueschists, Whiteschists, Greenschists, Hornblende Schist, Talc Schist, Chlorite Schist, Garnet Schist, Glaucophane schist.. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Taconite and Schist is white. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Schist 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 Schist is impact resistant, pressure resistant, water resistant.
