5 Formation

5.1 Formation

Coal formation takes place due to accumulation of plant debris in a swamp environment. The Coal formation process continues, as peat turns into lignite brown or black coal at increasing 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.

Lignite 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 Lignite and Taconite Reserves. Lignite is a soft brownish coal which shows traces of plants and is intermediate between bituminous coal and peat. 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 Lignite vs Taconite information and Lignite vs Taconite characteristics in the upcoming sections.

Lignite 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. Lignite vs Taconite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Lignite and Properties of Taconite. Learn more about Lignite vs Taconite in the next section. The interior uses of Lignite include Not yet used whereas the interior uses of Taconite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration. Due to some exceptional properties of Lignite and Taconite, they have various applications in construction industry. The uses of Lignite in construction industry include For road aggregate, Steel production and that of Taconite include As dimension stone, Used for flooring, stair treads, borders and window sills..

More about Lignite and Taconite

Here you can know more about Lignite and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Lignite and Taconite consists of mineral content and compound content. The mineral content of Lignite is not available and mineral content of Taconite includes Hematite, Magnetite, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Lignite vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Lignite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Taconite is available in red, reddish brown colors. Appearance of Lignite is Veined or Pebbled and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Lignite vs Taconite. The hardness of Lignite is 1 and that of Taconite is 5.5-6. The types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite 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 Lignite is black while that of Taconite is white. The specific heat capacity of Lignite 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.Lignite is heat resistant whereas Taconite is heat resistant, impact resistant, pressure resistant, wear resistant.
