例句

  1. The chemical characteristics indicate that the protolith of eclogites were possibly tholeiite with a continental affinity, whereas the garnet peridotites were derived from a depleted mantle.
  2. 地球化学研究揭示，榴辉岩的原岩很可能是形成在大陆内部构造环境的拉斑玄武岩，而石榴石橄榄岩可能是起源于亏损的残余地幔。
  3. The MORB and OIB of the Sanjiang area were generated from the depleted mantle and the primitive mantle respectively.
  4. 它们均属南半球地幔域。亏损地幔和近原始地幔分别是三江地区MORB和OIB的源区物质。
  5.
