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
Flint is a hard type of sedimentary rock that produces a small piece of burning material when hit by steel

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Flint is formed by the decomposition and compaction of various organisms such as sponges and diatoms under the water.
