Formation

Formation

Quartzite forms from sandstone and the mineral quartz being put under extreme heat and pressure.
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.

Quartzite vs Taconite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Quartzite and Taconite Reserves. Quartzite is a non-foliated metamorphic rock that forms by the metamorphism of pure quartz Sandstone. Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Quartzite vs Taconite information and Quartzite vs Taconite characteristics in the upcoming sections.

Quartzite 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. Quartzite vs Taconite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Quartzite and Properties of Taconite. Learn more about Quartzite vs Taconite in the next section. The interior uses of Quartzite include Countertops, Decorative aggregates, Flooring and Homes whereas the interior uses of Taconite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Quartzite and Taconite, they have various applications in construction industry.

More about Quartzite and Taconite

Here you can know more about Quartzite and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Quartzite and Taconite consists of mineral content and compound content. The mineral content of Quartzite includes Chlorite, Epidote, Hematite, Kyanite, Magnetite, Muscovite or Illite, Quartz 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 Quartzite vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Quartzite is available in black, blue, brown, green, light grey, purple, white, yellow colors whereas, Taconite is available in red, reddish brown colors. Appearance of Quartzite is Lustrous and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Quartzite vs Taconite. The hardness of Quartzite is 6-7 and that of Taconite is 5.5-6. The types of Quartzite are Orthoquartzite and Metaquartzite whereas types of Taconite are Iron formation. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Quartzite and Taconite is white. The specific heat capacity of Quartzite is 0.75 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.Quartzite is heat resistant, impact resistant, pressure resistant, wear resistant whereas Taconite is heat resistant, impact resistant, pressure resistant, wear resistant.
