| 摘 要： | 岩石化学研究表明，洋后变质超镁铁岩是由变质方辉橄榄岩和变质超镁铁堆积岩组成。变质方辉橄榄岩的微量元素地球化学及矿物化学特征表明，应为亏损的残余地幔产物。通过系统的岩石地球化学、矿物化学及年代学研究，认为洋后变质超镁铁岩可能为华南晚震旦－早古生代的蛇绿岩组成部分。

| Abstract: | Petrochemistry studies indicate that the Yanghou metamorphic ultramafic rocksare composed of metamorphosed harzburgite and burgite and ultramafic cumulate . Trace element geochemistry and mineral chemistry studies on the metamorphosed harzburgite indicate that it is the relict of the depleted mantle. From systematic studies on petrochemistry , mineral chemistry and geochronology, it's concluded that the Yanghou metamorphic ultramafic rocks are components of Later Sinian-Early Paleozoic ophiolite in South China . |
