Olivine is an important rock forming mineral and is common in mafic igneous rocks such as peridotite gabbro and basalt along with pyroxene and plagioclase The ultramafic rock dunite consists almost entirely of olivine and is the result of the fractional crystallization of peridotite composition melts to form cumulate olivine
