OIB的翻译

Based on more geochemical signatures, two types of basalt are recognized, namely, ocean island basalt ( OIB) and mid ocean ridge basalt ( MORB).

进一步的地球化学研究表明，这套玄武岩为洋岛型玄武岩（OIB）和洋中脊型玄武岩（MORB）的组合。

And ( 4) that the volcanic rocks mentioned above are ocean-island basalt ( OIB).

由岩石化学成分判别的结果表明，灰岩块体之下的火山岩为洋岛火山岩。

The study indicates strong composition differences between noble gases from MORB and OIB supporting two-layer mantle structure. Mantle degassing process is controlled mainly by SCD model.

研究表明，MORB源和OIB源玄武岩稀有气体组成差异强烈支持地幔双层结构的存在，地幔脱气过程主要受溶解度控制脱气模式（SCD）控制；
