Re-assessment of the paleoclimate implications of the Shell Bar in the Qaidam Basin dataset(about MIS 5)
CTR :91
Key words Shell Bar,Qaidam Basin
Relevant data The re-assessment of the Shell Bar in the Qaidam Basin, China, shows how a detailed multi-proxy investigation of sediments and fossils from a well-known paleoclimate archive may lead to a paradigm shift in comparison to many earlier studies. Our conclusion that the Shell Bar is a stream deposit, in contrast to earlier interpretations as a lake deposit, is based on sedimentological (grain size), paleoecological (bivalve, ostracods) and taphonomical (size measurements, records of articulated shells) data, as well as morphological and geological field observations in the wider vicinity of the Shell Bar. As a result, interpretation of the Shell Bar as a lake deposit, which has been generally accepted for almost three decades, now must be rejected. We hope our results will encourage others to critically assess paleoclimate data, even in cases where they are apparently well established and widely accepted. New paleoclimate studies will benefit from focusing on discrepancies with earlier data, and should avoid the tendency to find ‘supporting’ evidence for previously established paleoclimate inferences.
