Data are used to suggest and discuss a possible sequence of Holocene RSL changes. 3km wide and 25 km long with a maximum water-depth in the fjord of 160 m. Despite the steep fiord sides, depositional shorelines appear frequently along the fiord.
The study area, Saqqarliit Ilorliit, is located in the inner part of Akulliit, which is the middle of three large fiords on western Disko (Fig. The bedrock in the fiord consists of Tertiary basalts. Generally, littoral deposits consist of beach gravel. The wave climate on western Disko is characterized by wind generated waves and swell caused by cyclones in Davis Strait and Baffin Bay.
Saqqarliit Ilorliit comprises three cuspate forelands at the mouth of a hanging valley (Figs. The altitude of the cuspate forelands ranges from 0.9 to 1.5 m.a.s.l.Total C and S were determined by combustion in a LECO induction furnace and extractable metals (Ca, Mg, Na, K, Fe and Mn) were analysed using atomic absorption spectrophotometry (AAS). bekanntschaften Mannheim For metal extraction a simplified successive treatment with concentrated nitric acid and hydrochloric acid, suggested by Bengtsson and Enell (1986), was used to determine the acid-soluble amounts of various elements.3 ka, has been lower than at present (Mathiassen in Gabel-Jørgensen & Egedal 1940; Roussel 1941; Weidick 1976, 1993; Foged 1979; Rasch & Nielsen 1994, 1995; Rasch et al.1996), and that a transgression maximum occurred in the middle of the present century (Gabel- Jørgensen & Egedal 1940; Saxov 1958).

The coastal geomorphology of three cuspate forelands at Saqqarliit Ilorliit, western Disko, West Greenland is described, sediment core data from salt marshes and lagoons are presented, an emergence curve is constructed, and data are discussed in relation to late Holocene relative sea-level (RSL) changes. The coastal geomorphology at Saqqarliit Ilorliit suggest transgression early in the interval 2.5 -1.0 ka BP and between 0.7 ka BP and the present.On western Disko, falling RSL in early-middle Holocene was followed by rising RSL in late Holocene. The first transgression resulted in formation of an intertidal platform and coastal cliffs.Morten Rasch, Danish Polar Center, Strandgade 100H, 1401 Copenhagen K, Denmark; Bjarne Holm Jakobsen & Niels Nielsen, Institute of Geography, University of Copenhagen, Øster Voldgade 10, 1350 Copenhagen K., Denmark. In West Greenland information about late Holocene (Neoglacial, Local name: Vesterbygd glacial) relative sea-level (RSL) changes have been provided from scattered geological observations (Donner & Jungner 1975; Donner 1978; Foged 1979; Kelly 1979, 1980, 1985; Funder 1989), geomorphological observations (Binderup 1986; Bojsen & Frederiksen 1980; Rasch & Nielsen 1994, 1995; Rasch et al.3 ka BP (Donner & Jungner 1975; Kelly 1980, 1985; Funder 1989; Frich & Ingolfsson 1990).
It is also well established that RSL, at least in some parts of West Greenland during the last c.
The Holocene marine limit is situated between 60 and 65 m.a.s.l. Boulder beaches on the outer coasts indicate high energy conditions during storms.
The intensity of waves decreases eastwards along Akulliit.
The geomorphology of three cuspate forelands at Saqqarliit Ilorliit (Fig.
