Environmental Significance of the top of the Kreftenheye Formation in the lower Rhine Valley, Netherlands

The Kreftenheye Formation is a Late Pleistocene braided stream deposit of the Rhine River Valley in The Netherlands. The sediment properties and river processes that formed the deposit has been evaluated in previous studies, however, the nature of the unconformity at the top of the deposit has not been carefully studied. The approximately 3500 years of surficial exposure on the top of the Kreftenheye Formation records late glacial to early Holocene environmental change. Stratigraphic analysis of the top of the Kreftenheye Formation allows for comparison of the late glacial and post glacial processes in the Rhine River. Post glacial sedimentation buried the paleosurface in the Rhine Valley. Interpreted processes of deposition process raise questions about how the response of concurrent climate change and sea level rise creates significant geological unconformities in continental deposits.
