Cenozoic development of the depositional environment in the northern Cape Basin in relation to the Initiation of Northern Hemisphere Glaciation

北方冰川作用改变了全球洋流系统，也导致了开普盆地局部洋流状况的变化。气候和洋流的这种相互作用在沿着非洲西南部大陆边缘的沉积结构上留下了重要的印记。此外，构造运动塑造了沉积序列。为了了解不同因素对Cape盆地沉积层的堆积和组成的影响，需要从地震剖面和沉积学参数中提取（a）地震地层单元（事件层）的空间分布，（B）事件层处沉积物的物理和化学性质，以及（c）内陆的气候信息。反射地震记录与钻孔资料相结合，辅以孢粉资料，将提供开普盆地沉积体系的综合信息，阐明北方冰川作用的启动对即使远在南方的沉积环境的影响。

The Northern Hemisphere Glaciation modified the global current system leading also to changes in the local current situation in the Cape Basin. This interaction of climate and oceanic currents left a significant imprint in the sedimentary structures along the continental margin of southwestern Africa. Additionally, tectonic movements shaped the sedimentary sequences. To gain an understandig about the influence of the different factors on the build up and composition of the sedimentary layers in the Cape Basin the (a) spatial distribution of seismostratigraphics units (event horizons), (b) physical and chemical properties of sediments at event horizons, and (c) climate information of the hinterland need to be extracted from seismic profiles and sedimentological parameters. The combination of reflection seismic records with drill site information assited by palynological data will provide a comprehensive information of the sedimentary regime in the Cape Basin and elucidates the affect to Initiation of Northern Hemisphere Glaciation to depositional environment even located far away in the South.
