The stratigraphical position of the Edegem Sands Member (Berchem Formation, Miocene) in its type area at Wilrijk (N Belgium), based on planktonic foraminifera
Abstract
The glauconitic and fossiliferous Edegem Sands Member of the Berchem Formation (Miocene) in northern Belgium contains 25 different taxa of planktonic foraminifera. The presence of Globorotalia kugleri and Globigerinoides primordius allows to assign an Aquitanian age (Early Miocene) to the member. More accurately, this presence allows a correlation with Biozone N4, defined in tropical regions by Blow (1969,1979).
