The present study is based on seismic data and log interpretation from six wellslocated in the southern part of Jutland (Denmark). The Oligocène and Miocenesuccession has been subdivided into six depositional sequences. Most of the sequences are of Type 1. The development of the Oligocène and Miocene sequencessuggests a strong relationship with glacio-eustatic sea-level variations. Each sequence consists of a lowstand systems tract, which either corresponds to detachedprograding intervals or coarse-grained deposits, a transgressive systems tract, anda highstand systems tract. Changes in the overall pattern of the Oligocène andMiocene succession, however, suggest variation in elevation of the hinterland dueto different uplift of Fenno-Scandia and Baltic Shields. The depositional environment was characterized by shelf and nearshore sediments in a rapidly changingenvironment where the shoreline migrated/retreated across South Jutland severaltimes.
