The Quaternary sedimentary history and its relations to the pre-Quater
nary in the Kattegat region are reviewed. The Quaternary in the area i
s restricted to relatively young sediments, including scattered findin
gs of Saalian deposits and more continuous occurrences from the Eemian
, the Weichselian and the Holocene. Glacial and interglacial palaeoenv
ironmental reconstructions, including Holocene changes in oceanographi
c circulation, are reviewed, and the recent sedimentary processes and
the present hydrographic regime are outlined. Furthermore, Quaternary
and present tectonic activity in connection with some of the pre-Quate
rnary fault zones is discussed.
