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.

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