Geochemistry of basalts of ODP Hole 106-648B

Basalts from ODP Site 648, recovered from Serocki Volcano, a near-axis volcano on the Mid-Atlantic Ridge, are normal mid-ocean ridge basalts, depleted in K, Rb, and LREE. They...采自大西洋中脊（Mid-Atlantic Ridge）近轴火山谢罗茨基火山（Serocki Volcano）的大洋钻探计划（Ocean Drilling Program, ODP）648站位玄武岩，属于正常洋中脊玄武岩（normal mid-ocean ridge basalts），其钾（K）、铷（Rb）及轻稀土元素（Light Rare Earth Elements, LREE）含量亏损。此类玄武岩……
