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...
