A high-quality annually laminated sequence from Lake Belau, Northern Germany: Revised chronology and ist implications for palynological and tephrochronological studies
International audience The annually laminated record of Lake Belau offers an exceptional opportunity to investigate with high temporal resolution Holocene environmental change, aspects of climate history and human impact on the landscape. A new chronology based on varve counts, 14C-datings and heavy...
