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
Claystone is a fine-grained, dark gray to pink sedimentary rock which mainly consists of compacted and hardened clay

Archaeological Significance
Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Claystone is generally quite soft, but can be hard and brittle. It forms due to weathering of mudstone.

All about Boninite and Claystone Properties
Know all about Boninite and Claystone properties here. All properties of rocks are important as they define the type of rock and its application. Boninite belongs to Igneous Rocks while Claystone belongs to Sedimentary Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Claystone is Clastic. Boninite appears Dull and Soft and Claystone appears Rough and Dull. The luster of Boninite is vitreous while that of Claystone is dull. Boninite is available in bluish - grey, brown, green, grey colors whereas Claystone is available in black, blue, brown, green, grey, orange, red, white, yellow 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 Claystone are pottery.
