| Abstract: | Petrochemical studies indicate that the Yanghou metamorphic ultramafic rocks are composed of metamorphosed harzburgite and
ultramafic cumulate. Trace element geochemistry and mineral chemistry of the metamorphic harzburgite indicate that they are
relicts of depleted mantle. Systematic petrochemical, mineral chemical and geochronological studies led to such a conclusion
that the Yanghou metamorphic ultramafic rocks may be the components of Late Sinian-Early Paleozoic ophiolites in South China.
