摘要对赤道东太平洋海隆附近现代深海沉积物和孔隙流体进行了地球化学研究，以揭示成岩和热液活动。在原位温度下提取船上孔隙流体，以获得无热伪影的孔隙水数据。溶解的Cl SO4，Mg，Ca和K显示显着的变化从底层水的浓度，甚至通过各种沉积物类型从CaCO8软泥硅质软泥，红粘土，和“热液”重金属泥。然而，注意到了一些富集K的例子。溶解的Mn和SiO2，相比之下，显示显着的富集，与溶解度可能控制菱锰矿和海泡石，分别。未发现溶解组分清除的证据。
ABSTRACT Geochemical studies of sediments and pore fluids of recent deep sea sediments in the vicinity of the equatorial East Pacific Rise were carried out to delineate diagenetic and hydrothermal activity. Pore fluids were extracted onboard ship at in situ temperatures to yield the pore water data free of thermal artifacts. Dissolved Cl SO4, Mg, Ca, and K display remarkably few variations from bottom water concentrations even through various sediment types from CaCO8 ooze to siliceous ooze, red clay, and "hydrothermal" heavy metal muds. However, a few examples of enrichment of K were noted. Dissolved Mn and SiO2, in contrast, displayed marked enrichments, with solubilities likely controlled by rhodochrosite and sepiolite, respectively. No evidence for removals of dissolved components was found.
