Sedimentary and Climatic evolution of the Arctic (Canada and Svalbard) during the Late Paleozoic (SCALP 5)

在过去的几年里，北极的地质学一直是众多研究的焦点。这主要是由于该区存在、发现和预测了丰富的油气藏。但是，尽管人们普遍对该地区的地质学感兴趣，但大多数地质学研究都是针对特定主题的地区性研究。该项目旨在与其他项目(见第5.2章，相关项目)结合来自孤立沉积地区(斯维尔德鲁普盆地、加拿大和斯瓦尔巴群岛)的个人知识，以创建超区域概览。这里申请的第一个项目将集中于构造相对平静的斯维尔德鲁普盆地晚石炭世碳酸盐岩序列的区域演化和对比。在下一步中，我们将整合斯瓦尔巴群岛的晚石炭世剖面，以建立北极上石炭统旋回碳酸盐沉积的超区域对比。晚石炭世是冈瓦那二叠纪/石炭纪冰川运动的顶峰，冰川消退和消融导致海平面波动。在没有强烈的区域构造的情况下，这些构造在碳酸盐岩序列中保存良好，并可追踪到。每一个韵律交替的沉积旋回都显示出典型的向上浅化，突出表现为相和生物体的变化。连同生物地层连接点，以更大的有孔虫和牙形刺为标志，我们将首先建立加拿大旋回序列的对比，然后建立超区域直到斯瓦尔巴特群岛的对比。

During the last years the geology of the Arctic has been in the focus of numerous studies. This is mainly due to the presence, finding and prediction of rich oil- and gas reservoirs in this area. But despite of the general interest in the geology of the area, most of the geological studies are regional studies dealing with specific topics. This project aims, together with further projects (see chapter 5.2, linked projects), to combine this individual knowledge from isolated depositional areas (Sverdrup Basin, Canada, and Svalbard) to create a supra-regional overview. The first project step here applied for, will concentrate on the regional evolution and correlation of Late Carboniferous carbonate successions in the tectonically relatively quite Sverdrup Basin. In a later step we will integrate Late Carboniferous sections from Svalbard to establish a supra-regional correlation of Arctic Upper Carboniferous cyclic carbonate deposits. The Late Carboniferous is the zenith of the Permo/Carboniferous glaciation on Gondwana and the waning and waxing of these glaciers resulted in eustatic sea-level oscillations. In the absence of strong regional tectonics these are well preserved and traceable in carbonate successions. Each of these rhythmically alternating sedimentary cycles shows a typical shallowing upward, highlighted by facies and organism changes. Together with biostratigraphic tie-points, marked by larger foraminifera (fusulinids) and conodonts, we will establish first a correlation of the cyclic successions in Canada and later on supra-regional up to Svalbard.
