Foraminiferal stratigraphy in a marine Eemian- Weichselian sequence at Apholm, North Jutland.
Undisturbed core material is investigated for the first time from a marine Quaternary sequence through the Eemian of North Jutland. Core samples were examined from 86m-190m depth in a 202.6m deep boring at Apholm. The marine sequence from that interval was subdivided into four biozones based on its...

| Summary: | Undisturbed core material is investigated for the first time from a marine Quaternary sequence through the Eemian of North Jutland. Core samples were examined from 86m-190m depth in a 202.6m deep boring at Apholm. The marine sequence from that interval was subdivided into four biozones based on its foraminiferal content. Zone AP3 (190-140m) contains boreal and boreal-Lusitanian faunas indicating a water depth of at least 60-100m. This zone is referred to the Eemian Interglacial. The faunas of zone AP2 (140-113m) record the onset of a major deterioration in climate and a considerable shallowing of the marine environment. The climate is then seen to fluctuate between arctic and boreal-arctic in zone AP1 (113m to at least 86m). This indicates the succeeding stadial and interstadial periods. Zones AP2 and AP1 are referred to the Early and Middle Weicheselian.-from Author |
