Cryptotephra:A Powerful Tool for Independent Correlation and Precise Dating of Paleoclimate Records

摘要：

Detailed reconstructions of past climate variability, especially the regional variations in response to abrupt climate change, require precise correlation between disparate environmental archives. However, chronological uncertainties, such as the modeling and calibration issues in radiocarbon dating, or the counting errors in ice-core or varved lake records, have hindered the direct comparison of any of these vital paleoclimate records. The emergence of cryptotephra research in the past two decades has witnessed the great potential that it can offer, for linking numerous individual sequences in a wide geographical area (e.g., Lowe et al., 2012; Lane et al., 2013; Lowe et al., 2015). As part of a regional tephrostratigraphic study of terrestrial and marine records in NE Asia, we report on the presence of late Holocene B-Tm tephra in Lake Kushu, Northern Japan, which is located more than 1100 km away from the source volcano (i.e., Changbaishan) that generated the cryptotephra deposit (Chen et al., 2016).
