Definition
Marble is a non-foliated metamorphic rock which is composed of recrystallized carbonate which is formed when limestone is exposed to high temperatures and pressures over a long time
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica

Formation
Marble is a metamorphic rock produced from limestone in the earth crust. It is formed by the metamorphism of limestone.
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.

More about Marble and Taconite
Here you can know more about Marble and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Marble and Taconite consists of mineral content and compound content. The mineral content of Marble includes Garnet, Graphite, Olivine, Pyrite, Quartz and mineral content of Taconite includes Hematite, Magnetite, Quartz. You can also check out the list of all Metamorphic Rocks. When we have to compare Marble vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Marble is available in black, blue, brown, grey, pink, white colors whereas, Taconite is available in red, reddish brown colors. Appearance of Marble is Veined and Shiny and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Marble vs Taconite. The hardness of Marble is 3-4 and that of Taconite is 5.5-6. The types of Marble are Breccia Marble, Carrara Marble, Calacatta marble, Cultured Marble, Polished Marble, Honed Marble, Sand Marble whereas types of Taconite are Not Available. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Marble and Taconite is white. The specific heat capacity of Marble is 0.88 kJ/Kg K and that of Taconite is 3.20 kJ/Kg K. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Marble is heat resistant whereas Taconite is heat resistant, impact resistant, pressure resistant, wear resistant.
