Neogene fluvial and nearshore marine deposits of the Salten section, central Jylland, Denmark

The deposits of the Salten succession was laid down in a transgressive-regressive event during the latest Chattian (latest Oligocene) and/or the early Aquitanian (earliest Miocene). Five fades asso ciations are recognised and interpretated as deposited in 1: High-energy fluvial, 2: Low-energy fluvial, 3: Flood plain, 4: Tidally influenced fluvial, and 5: Marginal marine/delta plain environ ments. The dating by biostratigraphy indicates that the Salten succession correlates with the Vejle Fjord Formation. The succession correlates with fluvial deposits outcropping in gravel pits at Addit and Voervadsbro and thus these deposits are of latest Oligocene - earliest Miocene. This is in con trast to former studies that indicate a correlation with the upper Lower - Middle Miocene Odderup Formation. The age of the Salten succession as revealed from this study indicates that the Miocene deposits in Jylland are progressively truncated towards the north and east.
