Eemian Rhine delta architecture in The Netherlands: facies distribution, depoist characteristics and preservation potential in a near-coastal deltaic setting (original) (raw)

have been identified for the glaciation period: first a Glacier Maximum (GM) followed for a Minor Retreat (MR) and, finally, a Major Stabilization (MS); whereas the geomorphologic indicator of MS stage correspond with the principal moraine, the other two stages are based on other minor moraines and erratic boulders. Seven stages have been identified for the deglaciation period: four Major Deglaciation Retreats (MDR1, MDR2, MDR3 and MDR4) separated by three stages of Short Stabilization (SS1, SS2 and SS3); the MDR4 stage represents the final disappearance of the ice masses. These stages are based on recessional moraines, their corresponding secondary crests and erratic boulders. The dates based on 10 Be have provided a minimum ages of 26.2 AE0.8 to 24.6 AE0.7 ka BP for the GM stage, and 18.8 AE2.1 to17.1 AE0.9 ka BP for the MS stage. Based on available data from other researchers, the Major Deglaciation Retreat 3 (MDR3) could be dated on 16.2 AE1.5 to 15.7 AE0.7 ka BP. These chronologies do not include erosive rates corrections, which estimations are in progress and therefore final dates could be subject to slight modifications.
