Sedimentary and Climatic evolution of the Arctic (Canada and Svalbard) during the Late Paleozoic (SCALP 8)

该野外项目的科学重点是西斯匹次卑尔根岛Broggerhalvoya暴露的晚古生代沉积岩。这些地层记录了从陆地沉积环境到浅海、暖水碳酸盐台地的变化。这一发展反映了在以高频率和高幅度海平面波动为特征的全球冰库条件期间的一次重大海平面上升和海侵。这些有节奏的交替沉积旋回中的每一个都表现出典型的向上变浅，突出表现为相和生物的变化。结合以大型有孔虫（类）为标志的生物地层联系点，我们将建立西斯匹次卑尔根群岛的旋回地层图。该项目将结合以往侧重于斯匹次卑尔根岛中部和东部同生地层的国际研究项目的成果，提高对斯瓦尔巴德群岛晚古生代沉积盆地环境和沉积发展的局部、区域和总体认识。

The scientific focus of this field-based project is on Late Paleozoic sedimentary bedrocks, exposed at the Broggerhalvoya in western Spitsbergen. These strata record a change from terrestrial depositional environments to a shallow-marine, warm-water carbonate platform. The development reflects a major sea-level rise and transgression during a period of global icehouse conditions marked by high-frequency and high-amplitude sea-level fluctuations. 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) we will establish a cyclostratigraphic chart of western Spitsbergen. In combination with the results of previous international research projects focused on contemporaneous strata in central and eastern Spitsbergen, this project will improve the local, regional and general understanding of the environmental and depositional development of Svalbards Late Paleozoic sedimentary basins.
