Definition
A sedimentary rock, deposit of a submarine turbidity currents and are composed of layered particles
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
Turbidite is a type of sedimentary rock formed when a river carries or transports pieces of broken rock as it flows. These particles then settle down and are subjected to high temperature and pressures hence forming Turbidite.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
