“…The distribution of slides corresponds with the distribution of glaciomarine and marine fine-grained sediments (predominately clay and silt) that make up the major part (73%) of the total sedimentary fill of the Målselv valley ( Fig. 1; Eilertsen, 2002;Eilertsen et al, 2005Eilertsen et al, , 2006. The sediments were deposited in a fjord basin of variable depth, under relative sea-level fall, during and after the final retreat of the Fennoscandian ice sheet.…”

“…Areal deglaciation reduced fluvial discharge and the available sediment to that which could be mobilized and reworked by the palaeo-river system (Christiansen and Humlum, 1993). Progradation of the delta continued during the PRST, but the rate of progradation was probably slower than during the DHST due to the factors mentioned above Eilertsen et al, 2006). Despite the declining accommodation space, the sedimentary facies of FA III at the fjord-proximal sites (S1-S6) reflect deeper water conditions, as the delta prograded into the basin (Eilertsen et al, 2011).…”

“…Recent studies have presented models for infilling of formerly glaciated fjord valleys from Greenland (Hansen, 2001(Hansen, , 2004, Norway (Nemec et al, 1999;Eilertsen et al, 2006;Hansen et al, 2009;Eilertsen et al, 2011), Canada (Marchand et al, 2013), Sweden (Plink-Björklund andRonnert, 1999), and Germany (Winsemann et al, 2007). These investigations demonstrate that fjord valleys are primarily infilled during deglaciation and RSL fall, resulting in a complex stratigraphy, which can vary substantially between locations.…”

Abstract. The Zackenberg River delta is located in northeast Greenland (74 • 30 N, 20 • 30 E) at the outlet of the Zackenberg fjord valley. The fjord-valley fill consists of a series of terraced deltaic deposits (ca. 2 km 2 ) formed during relative sea-level (RSL) fall. We investigated the deposits using sedimentological and cryostratigraphic techniques together with optically stimulated luminescence (OSL) dating. We identify four facies associations in sections (4 to 22 m in height) exposed along the modern Zackenberg River and coast. Facies associations relate to (I) overriding glaciers, (II) retreating glaciers and quiescent glaciomarine conditions, (III) delta progradation in a fjord valley, and (IV) fluvial activity and niveo-aeolian processes. Pore, layered, and suspended cryofacies are identified in two 20 m deep ice-bonded sediment cores. The cryofacies distribution, together with low overall ground-ice content, indicates that permafrost is predominately epigenetic in these deposits. Fourteen OSL ages constrain the deposition of the cored deposits to between approximately 13 and 11 ka, immediately following deglaciation. The timing of permafrost aggradation was closely related to delta progradation and began following the subaerial exposure of the delta plain (ca. 11 ka). Our results reveal information concerning the interplay between deglaciation, RSL change, sedimentation, permafrost aggradation, and the timing of these events. These findings have implications for the timing and mode of permafrost aggradation in other fjord valleys in northeast Greenland.
