Description
Summary:Skeldal is a northeast-trending valley in the Mesters Vig district, on the southwest shore of Kong Oscars Fjord, about 70 km from the fiord's entrance, in the northeast corner of Scoresby Land. Thirteen radiocarbon dates of shell material which were used to establish a rate of emergence in Skeldal, indicate that the valley was partially open to the sea by ca 8500 BP. Early emergence (8000-7000 BP) was approx 3 m/century. Emergence is related almost entirely to adjustment due to glacial unloading. Gauchissement postglaciaire à Skeldal, nord-est du Groënland. Treize spécimens du matériaux conchologiques, recueillis à Skeldal, district de Mesters Vig, au nord-est du Groënland, ont été datés par la méthode du radiocarbone et ont permis d'établir la vitesse d'émergence tout au cours du gauchissement. Les dates indiquent Skeldal était partiellement exposé à la mer c 8,500 av. p. Au début (8,000-7,000 av. p.) l'émergence était environ de 3 m. par siècle. L'émergence dépend presque entièrement du règlement isostatique causé par la décharge glaciale.
