Definition
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
Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
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 Boninite and Taconite
Here you can know more about Boninite and Taconite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Boninite and Taconite consists of mineral content and compound content. The mineral content of Boninite includes Amphibole, Apatite, Biotite, Feldspar, Garnet, Hornblade, Ilmenite and mineral content of Taconite includes Hematite, Magnetite, Quartz. You can also check out the list of all Igneous Rocks. When we have to compare Boninite vs Taconite, the texture, color and appearance plays an important role in determining the type of rock. Boninite is available in bluish - grey, brown, colourless, green, grey colors whereas, Taconite is available in red, reddish brown colors. Appearance of Boninite is Dull and Soft and that of Taconite is Layered, Banded, Veined and Shiny. Properties of rock is another aspect for Boninite vs Taconite.
