Archaeological Significance
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.
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.

More about Taconite and Anthracite
Here you can know more about Taconite and Anthracite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Anthracite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Anthracite includes Calcite, Clay, Clay Minerals. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Anthracite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Anthracite 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 Anthracite is Veined or Pebbled. Properties of rock is another aspect for Taconite vs Anthracite. The hardness of Taconite is 5.5-6 and that of Anthracite is 1-1.5. The types of Taconite are Iron formation whereas types of Anthracite are Semi-anthracite and Meta-anthracite. 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 Anthracite is black. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Anthracite is 1.32 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 Anthracite is heat resistant, water resistant.
