西北印度洋中脊玄武岩源区地幔特征OA北大核心CSCDCSTPCD
Mantle source features of basalts in the Northwest Indian Ridge
利用全球岩石地球化学数据库(PetDB)中有关卡尔斯伯格洋脊(CR)、北中印度洋脊(NCIR)及南中印度洋脊(SCIR)玄武岩的微量元素及同位素组成数据,分析了玄武岩的元素地球化学特征及其沿脊轴的变化,旨在探讨玄武岩源区地幔的(不)均一性及岩浆作用过程的差异。初步研究结果表明： CR、NCIR及 SCIR 玄武岩组成相近,仅在个别脊段表现有微量稀土元素和同位素组成上的差异,玄武岩整体与N-MORB组成特征相近,与先前通常认为的典型印度洋中脊玄武岩…查看全部>>
The geochemical features and variation in major elements, trace elements, and isotopic compositions of CR, NCIR, and SCIR MORBs, collected from the PetDB database, are examined to investigate mantle source het-erogeneity and the variation in magmatic processes along a ridge axis. The trace element and isotopic composition of the basalts are nearly identical to that of N-MORB, except for an anomaly in some segments, and are different from typical Indian Ridge…查看全部>>
