The tephrostratigraphy of lake sediments in the Endinger Bruch provides the first robust age model for the Lateglacial palynological records of Vorpommern (north-east Germany). Cryptotephra investigations revealed six tephra layers within sediments spanning from Open vegetation phase I (similar to Bolling, similar to 15 ka) to the Early Holocene Betula/Pinus forest phase (similar to Pre-boreal, similar to 10.5 ka). Four of these layers have been correlated with previously described tephra layers found in sites across Europe. The Laacher See Tephra (Eifel Volcanic Field) is present in very high concentrations within sediments of the Lateglacial Betula (/Pinus) forest phase (similar to Allerod). The Vedde Ash (Iceland) lies midway through Open vegetation phase III (similar to Younger Dryas). The Hasseldalen and the Askja tephras (Iceland) lie in the Early Holocene Betula/ Pinus forest phase (similar to Preboreal). These tephra layers have independently derived age estimates, which have been imported into the Endinger Bruch record. Furthermore, the layers facilitate direct correlation of the regional vegetation record with other palaeoenvironmental archives, which contain one or more of the same tephra layers, from Greenland to Southern Europe. In doing this, localized variations are confirmed in some aspects of the pollen stratigraphy; however, transitions between the main vegetation phases appear to occur synchronously (within centennial errors) with the equivalent environmental transitions observed in sites across the European continent.
