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
Latite is an igneous, volcanic rock, with aphanitic-aphyric to aphyric-porphyritic texture

Formation
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
Latite is a fine-grained, hard rock which is a type of metasomatite, essentially altered basalt. It forms with or without crystallization, either below the surface as intrusive rocks or on the surface as extrusive rocks.
