Formation

Formation

Anthracite forms from the accumulation of plant debris in a swamp environment. When plant debris dies and falls into the swamp, the standing water of the swamp protects it from decay.
The banded iron layers are formed in sea water when oxygen is released by photosynthetic cyano-bacteria. The oxygen then combines with dissolved iron in ocean to form insoluble iron oxides, which precipitated out, forming a thin layer of banded iron formation on ocean floor.

More about Anthracite and Banded iron formation

Here you can know more about Anthracite and Banded iron formation. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Anthracite and Banded iron formation consists of mineral content and compound content. The mineral content of Anthracite includes Calcite, Clay, Clay Minerals and mineral content of Banded iron formation includes Hematite, Magnetite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Anthracite vs Banded iron formation, the texture, color and appearance plays an important role in determining the type of rock. Anthracite is available in black, brown, dark brown, grey, light to dark grey colors whereas, Banded iron formation is available in red, reddish brown colors. Appearance of Anthracite is Veined or Pebbled and that of Banded iron formation is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Anthracite vs Banded iron formation. The hardness of Anthracite is 1-1.5 and that of Banded iron formation is 5.5-6. The types of Anthracite are Semi-anthracite and Meta-anthracite whereas types of Banded iron formation are Algoma-type , Lake Superior-type, Superior-type and Taconite. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Anthracite is black while that of Banded iron formation is white. The specific heat capacity of Anthracite is 1.32 kJ/Kg K and that of Banded iron formation is 3.20 kJ/Kg K.
