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
Aplite is a fine-grained granite composed mainly of feldspar and quartz

Archaeological Significance
Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Aplites belong to intrusive igneous rocks which are mostly quart and alkali feldspar and are formed from residual eutectic granitic liquids and represent the final crystallization products of magma.

All about Boninite and Aplite Properties
Know all about Boninite and Aplite properties here. All properties of rocks are important as they define the type of rock and its application. Boninite and Aplite belong to Igneous Rocks.Texture of Boninite is Aphanitic to Porphyritic whereas that of Aplite is Granular, Graphic. Boninite appears Dull and Soft and Aplite appears Veined or Pebbled. The luster of Boninite is vitreous while that of Aplite is dull to pearly to subvitreous. Boninite is available in bluish - grey, brown, green, grey colors whereas Aplite is available in black, grey, orange, pink, 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 Aplite are curling, gemstone, laboratory bench tops, small sculptures, tombstones.
