1 Definition

1.1 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

5 Formation

5.1 Formation

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

Due to change in environmental conditions, rocks are heated and pressurized deep inside the Earth's surface. Pseudotachylite is formed from the extreme heat caused by magma or by the intense collisions and friction of tectonic plates.
