Rapid early-Holocene environmental changes in northern Sweden based on studies of two varved lake-sediment sequences
Mineral magnetic, organic carbon and pollen studies of two varved Holocene lake-sediment sequences in the boreal forest of northern Sweden indicate that significant environmental changes took place between c. 6000 and 5700 BC. This interval is characterized by an increase in mineral-matter accumulation, which is a proxy for winter-snow accumulation, and a statistically significant decrease in tota
