Definition
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica
During the impact melted material forming a breccia containing glass and crystal or lithic fragments together form Suevite rock.

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.
Suevite is a metamorphic rock consisting partly of melted material, typically forming a breccia containing glass and crystal or lithic fragments, formed during an impact event.

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 Suevite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Taconite and Properties of Suevite. Learn more about Taconite vs Suevite in the next section. The interior uses of Taconite include Decorative aggregates, Entryways, Flooring, Homes and Interior decoration whereas the interior uses of Suevite include Decorative aggregates, Homes and Interior decoration. Due to some exceptional properties of Taconite and Suevite, 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 Suevite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement, Manufacture of magnesium and dolomite refractories.
More about Taconite and Suevite
Here you can know more about Taconite and Suevite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Suevite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Suevite includes Coesite, Quartz, Stishovite. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Suevite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Suevite is available in black, brown, colourless, green, grey, pink colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Suevite is Banded. Properties of rock is another aspect for Taconite vs Suevite. The hardness of Taconite is 5.5-6 and that of Suevite is 5.5. The types of Taconite are Not Available whereas types of Suevite are Phyllosilicates, Calcite. 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 Suevite is light to dark brown. The specific heat capacity of Taconite is 3.20 kJ/Kg K and that of Suevite is 0.92 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 Suevite is heat resistant.
