Composition and accumulation rates of bottom sediments from Core ASV16-1372, Voring Plateau

Based on sedimentological, mineralogical, geochemical, and micropaleontological data on comprehensively investigated Core ASV16-1372, Late Pleistocene - Holocene sedimentation history is reconstructed for the Voring marginal plateau (continental margin of the Norwegian Sea). An age model constructed is based on correlation with several adjacent cores, for which AMS radiocarbon datings are available. Lithostratigraphic correlation made it possible to compare stratigraphic division of Core ASV16-1372 with other cores sampled on the Voring Plateau and the shelf and continental slope off Central Norway. It is concluded that compositional and structural features of bottom sediments are correlated with paleoclimatic and paleoceanographic changes, variations in provenances, as well as agents and pathways of sedimentary material transport.本研究基于对ASV16-1372岩芯的沉积学、矿物学、地球化学与微古生物学综合分析数据，重建了挪威海大陆缘沃林边缘高原（Voring marginal plateau）晚更新世-全新世的沉积演化历史。研究所构建的年龄模型以与若干已获取加速器质谱（AMS）放射性碳测年数据的相邻岩芯的对比为依据。通过岩石地层对比，可将ASV16-1372岩芯的地层划分方案，与沃林高原以及挪威中部外海陆架、大陆坡所采集的其他岩芯进行比对。研究结论表明，海底沉积物的组成与结构特征，与古气候、古海洋环境变化、物源区变化以及沉积物搬运营力和搬运路径均存在相关性。
