Geology, palynology and age of pingo remnant near Daarle, Province of Overijssel, the Netherlands

Abstract

Detailed investigations were carried out on a pingo remnant near Daarle in the province of Overijssel, The Netherlands. The pingo developed in an abandoned alluvial plain after the end of the fluvial activity. The time of both the pingo growth and the first part of the decay must be placed before the end of the deposition of the Older Coversand I, which means between about 28 000 BP and 23 000 BP. After partial melting the remaining ice-core formed a level surface that was covered with Older Coversand I and deposits of the Beuningen Complex. Final melting of the ice-core was retarded until shortly before the Bølling Interstadial, when a lake was formed in which organic material accumulated.
