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.
  
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

Taconite vs Aplite 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 Aplite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Taconite and Properties of Aplite. Learn more about Taconite vs Aplite in the next section. The interior uses of Taconite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Aplite include Bathrooms, Countertops, Decorative aggregates, Entryways, Floor tiles, Homes, Hotels, Kitchens and Stair treads. Due to some exceptional properties of Taconite and Aplite, 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 Aplite include As dimension stone.
More about Taconite and Aplite
Here you can know more about Taconite and Aplite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Aplite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Aplite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Aplite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Aplite is available in black, grey, orange, pink, white colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Aplite is Veined or Pebbled. Properties of rock is another aspect for Taconite vs Aplite. The hardness of Taconite is 5.5-6 and that of Aplite is 6.5. The types of Taconite are Not Available whereas types of Aplite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Taconite and Aplite is white. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Aplite is 0.79 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 Aplite is heat resistant, wear resistant.
