众所周知,斜坡地形控制着板内海山沉积物的空间分布;但是,对斜坡地形的变化如何制约这些沉积模式知之甚少。在这项研究中,我们分析了在海山斜坡上发现的四种岩石类型的数据,包括主要由富钴结壳组成的胶体化学矿床,并研究了这些岩石类型的空间分布与当前斜坡地形之间的关系。我们使用这些关系来讨论沉积模式的斜坡地形变化的约束。钻孔岩芯样品中的一些沉积单元被解释为是由过去的地形变化造成的,这些地形变化形成了当前的斜坡地形。在同一地点堆积的两种或多种类型的沉积物意味着斜坡地形随着时间的推移而变化,并且海山斜坡的沉积模式受到斜坡地形变化的限制。
Slope topography is known to control the spatial distribution of deposits on intraplate seamounts; however, relatively little is known about how slope topography changes constrain those depositional patterns. In this study, we analyse data on four lithotypes found on seamount slopes, including colloidal chemical deposits comprising mainly cobalt-rich crusts, and examine the relationships between the spatial distribution of these lithotypes and current slope topography. We use these relationships to discuss depositional patterns constrained by slope topography changes. Some depositional units in drill core samples are interpreted to have resulted from past topographic changes that created the current slope topography. Two or more types of deposits that accumulated at the same location implies that the slope topography changed over time and that the depositional patterns on seamount slopes are constrained by changes in slope topography.
