Definition
Dolomite is a sedimentary rock containing more than 50 percent of the mineral dolomite by weight
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
Dolomite rocks are originally deposited as calcite or aragonite rich limestone, but during diagenesis process, the calcite or aragonite is transformed into dolomite.
Boninite is a type of Igneous rock which is formed through the cooling and solidification of lava or existing rocks.
