Definition
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica
Boninite is a mafic extrusive rock which is high in magnesium and silica content, formed in fore-arc environments, typically during the early stages of subduction

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.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

More about Taconite and Boninite
Here you can know more about Taconite and Boninite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Taconite and Boninite consists of mineral content and compound content. The mineral content of Taconite includes Hematite, Magnetite, Quartz and mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite. You can also check out the list of all Sedimentary Rocks. When we have to compare Taconite vs Boninite, the texture, color and appearance plays an important role in determining the type of rock. Taconite is available in red, reddish brown colors whereas, Boninite is available in bluish - grey, brown, colourless, green, grey colors. Appearance of Taconite is Layered, Banded, Veined and Shiny and that of Boninite is Dull and Soft. Properties of rock is another aspect for Taconite vs Boninite. The hardness of Taconite is 5.5-6 and that of Boninite is 7. The types of Taconite are Not Available whereas types of Boninite are Not Available.
