Resumé
The biostratigraphy of the Miocene sediments of the Lille Tønde
borehole, southern Jutland (Denmark), was studied by means of
dinoflagellate cysts, foraminifers and molluscs. Based on this study, it
is shown that the boundaries of the Northwest European stages are not
isochronous with the global stratotypes, but overall they are slightly
older. The investigated strata spans most of the Miocene from the
Northwest European Hemmoorian to Syltian Stages (Lower Miocene to Upper
Miocene-lowermost Pliocene?). Based on the results from the Lille Tønde
borehole, the Hemmoorian-Reinbekian boundary (the north-western European
boundary between the Lower and Middle Miocene) correlates with the
intraupper Burdigalian (Lower Miocene). The Reinbekian Stage
(north-western European "Middle Miocene") correlates with the
Langhian?-lower Serravallian Stage (Middle Miocene), making the "Middle
Miocene" of north-western Europe older than the globally defined Middle
Miocene. The Langenfeldian Stage (north-western European "Middle
formerly-Upper Miocene") correlates with the mid-Serravallian Stage
(Middle Miocene). The succeeding Gramian and Syltian Stages
(north-western European Upper Miocene) correlate with the upper
Serravallian-Tortonian (upper Middle-Upper Miocene) and Messinian Stages
(uppermost Miocene), respectively.
