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.

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.

More about Taconite and Lignite

Here you can know more about Taconite and Lignite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Lignite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Lignite includes . You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Lignite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Lignite is available in black, brown, dark brown, grey, light to dark grey colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Lignite is Veined or Pebbled. Properties of rock is another aspect for Taconite vs Lignite. The hardness of Taconite is 5.5-6 and that of Lignite is 1. The types of Taconite are Iron formation whereas types of Lignite are Xyloid Lignite or Fossil Wood and Compact Lignite or Perfect Lignite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Taconite is white while that of Lignite is black. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Lignite is 1.26 kJ/Kg K. 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 Lignite is heat resistant.
