Depleted ophiolitic relict slice, consisting of mantle peridotite and two suites of cumulates (composed of dunite, diopsidite, wehrlite and gabbro). The cumulates include three magmatic cycles, and each cycle shows a magmatic evolution trend from ultramafic to mafic. Petrochemical and mineralogical data indicate that they were formed by crystal accumalation of the Mg- and Cr-rich tholeiitc magma in an opening system under high pressure. Ore bodies of economic grade occur in dunite and pyroxene-bearing dunite cumulates at the bottom of the third cycle, while only a few lean ore bodies are seen in the mantle peridotite.
