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.
Basalt forms when lava reaches the Earth's surface near an active volcano. The temperature of lava is between 1100 to 1250° C when it gets to the surface.

Taconite vs Basalt 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 Basalt characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Taconite and Properties of Basalt. Learn more about Taconite vs Basalt in the next section. The interior uses of Taconite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Basalt include Floor tiles, Homes, Hotels and Kitchens. Due to some exceptional properties of Taconite and Basalt, 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 Basalt include Arrowheads, As dimension stone, Cobblestones, Cutting tool, Rail track ballast, Roadstone.
More about Taconite and Basalt
Here you can know more about Taconite and Basalt. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Basalt consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Basalt includes Olivine, Plagioclase, Pyroxene. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Basalt, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Basalt is available in black, brown, light to dark grey colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Basalt is Dull and Soft. Properties of rock is another aspect for Taconite vs Basalt. The hardness of Taconite is 5.5-6 and that of Basalt is 6. The types of Taconite are Not Available whereas types of Basalt are Alkaline Basalt, Boninite, High Alumina Basalt, Mid Ocean Ridge Basalt (MORB), Tholeiitic Basalt, Basaltic trachyandesite, Mugearite and Shoshonite. 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 Basalt is white to grey.
