Dunite Formation Processes in Highly Depleted Peridotite ...

2002-3-1  Residual dunite is formed after extensive partial melting of peridotite. Cumulative dunite is formed by fractionation of olivine from a mafic melt. Replacive dunite is a product of the reaction between a pyroxene-bearing host rock and an olivine-saturated magma, which dissolves orthopyroxene in the host peridotite and sometimes crystallizes ...
