Petrology and geochemistry of basalts from the Vavilov Basin

During ODP Leg 107, two holes were drilled in the basement of Vavilov Basin, a central oceanic area of the Tyrrhenian sea. Hole 655B is located near the Gortani ridge in off-axis position at the western rim of the basin; Hole 651A is located on a basement swell at the axis of the basin. This paper deals with mineral chemistry, major and trace element geochemistry, and petrogenesis of the basalts recovered in the two holes. […]

在大洋钻探计划（Ocean Drilling Program, ODP）第107航次期间，科研人员在第勒尼安海中央洋区——瓦维洛夫海盆的基底处钻取了两个钻孔。655B号钻孔位于该海盆西缘离轴位置的戈尔塔尼海岭附近；651A号钻孔则位于该海盆轴部的基底隆起带之上。本文针对这两个钻孔所获取的玄武岩开展了矿物化学、主量与微量元素地球化学以及岩石成因学相关研究。[…]
