Definition
Aplite is a fine-grained granite composed mainly of feldspar and quartz
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
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.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.

All about Aplite and Boninite Properties
Know all about Aplite and Boninite properties here. All properties of rocks are important as they define the type of rock and its application. Aplite and Boninite belong to Igneous Rocks.Texture of Aplite is Granular, Graphic whereas that of Boninite is Aphanitic to Porphyritic. Aplite appears Veined or Pebbled and Boninite appears Dull and Soft. The luster of Aplite is dull to pearly to subvitreous while that of Boninite is vitreous. Aplite is available in black, grey, orange, pink, white colors whereas Boninite is available in bluish - grey, brown, colourless, green, grey colors. The commercial uses of Aplite are curling, gemstone, laboratory bench tops, small sculptures, tombstones and that of Boninite are an oil and gas reservoir, cemetery markers, creating artwork, soil conditioner, source of magnesia (mgo).
