Pollen records from lakes in Mecklenburg, Germany

The oldest lacustrine sediments of the cores from seven kettle-hole lakes in the Frankfurt Stadium in Mecklen-burg-Vorpommern were deposited during the Alleroed. The dead-ice melted rapidly in the mid-Alleroed. The Laachersee-tephra was found in the lakes east of Lake Müritz, the Saksunarvatn tephra occurred in two lakes. The sediments are generally non-laminated, varves occurred only in isolated sections of a few of these lakes. Relatively high percentages of pine characterize the pollen profiles during the upper part of the Lateglacial. However, the vegetation history shows all the features known from profiles in northwestern Germany. The lower values of hazel towards the eastern part of the transect point to an increasing continentality during the Boreal
