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

Argillites are highly compact sedimentary or slightly metamorphosed rocks that consist largely or wholly of particles of clay or silt but lack the fissility of shale or the cleavage characteristic of slate

Etymology

From its occurrence in the Izu-Bonin arc south of Japan

From Latin Argilla (clay) and -ite in English which became agrilla+ -ite = Argillite

Formation

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

An argillite is a fine-grained sedimentary rock mainly composed of clay particles which forms from lithified muds which contain variable amounts of silt-sized particles.

All about Boninite and Argillite Properties

Know all about Boninite and Argillite properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Argillite belongs to Sedimentary Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Argillite is Clastic, Polished. Boninite appears Dull and Soft and Argillite appears Rough and Dull. The luster of Boninite is vitreous while that of Argillite is waxy and dull. Boninite is available in bluish - grey, brown, green, grey colors whereas Argillite is available in dark grey to black, pink, red, white 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 Argillite are fire resistant, used to manufracture paperweights and bookends.
