Abstract:

The Sydra Formation is a widespread interglacial complex in the North
Volcanic Zone, Iceland, from the sector of the Askja volcano down to
Oxarfjordur at the north coast. It probably corresponds to OIS 5e, 5d
and 5c. Subsequently, the region was covered by the Weichselian ice cap.
It is significant as well for the understanding of the OIS 6
deglaciation and its relations to volcanism as also for the erosional
budget of the Saalian, warm based and Weichselian, cold based,
glaciations. A topographic bulge linked with a rapid glacio-isostatic
rebound, downstream of the Jokulsa a Fjolum river, is responsible for
the development of the Sydra lacustrine deposits. An early abrupt event
(Sy2), the Sydra ash probably corresponds to ash zone B as on the
northern Iceland shelf and possibly an abrupt cooling. It presents no
similarity with the Fossvogur formation in the Reykjavik district. The
meaning of the formation is significant in term of rift activity and of
palaeoclimate for OIS 5. (C) 2001 Academie des sciences / Editions
