Definition

Arkose is a sedimentary rock, specifically a type of sandstone containing at least 25% feldspar

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

Arkose rock forms from the weathering of feldspar-rich igneous or metamorphic rock, most commonly granitic rocks, which are primarily composed of quartz and feldspar.

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

All about Arkose and Boninite Properties

Know all about Arkose and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Arkose belongs to Sedimentary Rocks while Boninite belongs to Igneous Rocks.Texture of Arkose is Clastic whereas that of Boninite is Aphanitic to Porphyritic. Arkose appears Rough and Dull and Boninite appears Dull and Soft. The luster of Arkose is dull while that of Boninite is vitreous. Arkose is available in reddish brown colors whereas Boninite is available in bluish - grey, brown, green, grey colors. The commercial uses of Arkose are in aquifers, soil conditioner, source of magnesia (mgo), tombstones and that of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
