1.1 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

5.1 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.
