Geochemistry of Mid-Atlantic Ridge sediments

Geochemical compositions and Sr and Nd isotopes were measured in two cores collected ~2 and 5 km from the Rainbow hydrothermal vent site on the Mid-Atlantic Ridge. Overall, the...在大西洋中脊（Mid-Atlantic Ridge）的彩虹热液喷口站点（Rainbow hydrothermal vent site）附近，采集了两根分别距该站点约2千米与5千米的岩芯（core），并对其地球化学组成以及锶（Sr）、钕（Nd）同位素组成进行了测定。总体而言，……
