The evidences indicate that the magmas are formed by melting of pyrolite and eclogite (ancient basaltic oceanic crust) in the axial zone of mantle plume.
这说明它们是在地幔柱轴部，由地幔岩和榴辉岩(古玄武质洋壳)组成的源区产生的岩浆形成的。
The existence of recycled basaltic oceanic crust in the axial zone of mantle plume may be the key of the formation of giant V-Ti-magnetite deposits.
岩浆源区再循环玄武质洋壳的存在可能是该区超大型钒钛磁铁矿床形成的根本原因。
