5 Formation

5.1 Formation

Picrite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.

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.

Picrite 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 Picrite and Taconite Reserves. Picrite is a variety of high-magnesium olivine basalt that is very rich in the mineral olivine. 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 Picrite vs Taconite information and Picrite vs Taconite characteristics in the upcoming sections.

More about Picrite and Taconite

Here you can know more about Picrite and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Picrite and Taconite consists of mineral content and compound content. The mineral content of Picrite includes Biotite, Olivine, Plagioclase, Pyrrhotite 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 Picrite vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Picrite is available in black, brown, colourless, green, grey, pink, white, yellow colors whereas, Taconite is available in red, reddish brown colors. Appearance of Picrite is Rough and Shiny and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Picrite vs Taconite. The hardness of Picrite is 6.8 and that of Taconite is 5.5-6. The types of Picrite are Oceanite 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 Picrite and Taconite is white, greenish white or grey. The specific heat capacity of Picrite is 0.88 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.Picrite is heat resistant whereas Taconite is heat resistant, impact resistant, pressure resistant, wear resistant.
