Based on the dominant types of algae contained in the sediment, the biogenic varves can be classified into dinocyst-biogenic varves (0¨C63 cm) and mixed (dinocyst and diatom)-biogenic varves (214¨C632 cm). In this paper, the formation process and components of the varve are described, the possible reason for the types of varve changing throughout the record is discussed and a high-resolution varve chronology is established spanning the last 13 ka BP. Although further varve counting and error assessment are needed, the results presented here represent a solid foundation for studying the palaeoclimate record of Erlongwan maar lake. %K biogenic varve %K clastic varve %K dinocyst %K varve chronology %U http://link.springer.com/article/10.1007/s11434-007-0448-x
