英文縮寫DM的擴展資料

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.地球化學研究揭示，榴輝巖的原巖很可能是形成在大陸內部構造環境的拉斑玄武巖，而石榴石橄欖巖可能是起源于虧損的殘余地幔。
2. The MORB and OIB of the Sanjiang area were generated from the depleted mantle and the primitive mantle respectively.它們均屬南半球地幔域。虧損地幔和近原始地幔分別是三江地區MORB和OIB的源區物質。
3. Accordingly, the northern and southern parts of Xinjiang can be divided into two obviously different isotopic geochemical provinces : the northern province is characterized by isotopic compositions of the depleted mantle, whereas the southern province by isotopic compositions of the enriched mantle.據此，可以將新疆南部和北部劃分為兩個明顯不同的同位素地球化學省。南部省以富集型地幔的同位素組成為特征，而北部省以虧損型地幔的同位素組成為特征。
4. The second source is the depleted mantle, which lies underneath the mid-eastern transform domain. Basalts from this source have low 87Sr / 86Sr isotopic compositions, lower REEs and trace elements and higher contents.另一個是位于轉換斷層中-東部下面的虧損地幔，來自這個地幔源的玄武巖具有低87Sr/86Sr、低稀土元素和微量元素含量，但MgO含量較高。
5. Trace element geochemistry and mineral chemistry studies on the metamorphosed harzburgite indicate that it is the relict of the depleted mantle.變質方輝橄欖巖的微量元素地球化學及礦物化學特征表明，應為虧損的殘余地幔產物。
