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

Archaeological Significance
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.

All about Boninite and Taconite Properties
Know all about Boninite and Taconite properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Taconite belongs to Sedimentary Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Taconite is Banded, Trellis. Boninite appears Dull and Soft and Taconite appears Layered, Banded, Veined and Shiny. The luster of Boninite is vitreous while that of Taconite is earthy. Boninite is available in bluish - grey, brown, green, grey colors whereas Taconite is available in red, reddish brown colors. The commercial uses of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo) and that of Taconite are as a touchstone, cemetery markers, creating artwork.
