Definition
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay
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
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

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