The study of geochemistry indicates that these metabasic volcanic rocks are characterized with N-type MORB (mid-ocean ridge basalt).
地球化学研究表明，其为典型的大洋拉斑玄武岩（MORB型玄武岩）。
It is tentatively suggested that the lower lithosphere MORB-OIB mantle is recently accreted since the paleo-lithosphere mantle was replaced by the abnormal asthenosphere.
我们初步认为，该区深部岩石圈MORB - OIB地幔可能是软流圈置换古岩石圈地幔而增生形成的。
All the eclogite samples with the feature of both E-MORB and OIB indicate a plume-ridge interaction or hotspot-ridge interaction during the evolution process of Paleo-Tethys.
样品同时具备E-MORB和OIB的特征，说明古特提斯洋在漫长的演化过程中可能存在地幔柱岩浆和正常洋中脊亏损地幔岩浆的相互作用。
