1 Definition
1.1 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

5 Formation
5.1 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.
