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.
Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

Taconite vs Arkose 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 Arkose characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Taconite and Properties of Arkose. Learn more about Taconite vs Arkose in the next section. The interior uses of Taconite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Arkose include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Taconite and Arkose, 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 Arkose include Cement manufacture, Construction aggregate, For road aggregate, Production of glass and ceramics, Raw material for the manufacture of mortar.
More about Taconite and Arkose
Here you can know more about Taconite and Arkose. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Arkose consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Arkose includes Calcite, Clay, Clay Minerals, Feldspar, Micas, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Arkose, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Arkose is available in reddish brown colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Arkose is Rough and Dull. Properties of rock is another aspect for Taconite vs Arkose. The hardness of Taconite is 5.5-6 and that of Arkose is 6-7. The types of Taconite are Iron formation whereas types of Arkose are Arkose. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Taconite and Arkose is white. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Arkose is 0.78 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 Arkose is heat resistant, impact resistant, pressure resistant.
