Luminescence Chronology for DZK01 Core from Shandong peninsula of the coastal Bohai Sea in China.

The Shandong peninsula along the coastal Bohai Sea in China is mainly a vast alluvial plain formed by the Yellow River, and it is an ideal area to study the evolution oflandform in a river-sea interaction area in which chronology is the key. However, the detailed OSL chronology of cores in this area is lacking. In this study 22 OSL samples have been collected from the upper 40 meters of DZK01 core (100m in depth) to establish a chronology using quartz Single Aliquot Regeneration (SAR) + Standard Growth Curve (SGC) methods. Preheat plateau test and laboratory dose recovery test showed that the SAR protocol was applicable to these samples whose recuperation was negligible. Three radiocarbon samples were also dated for cross-checking. Sedimentation rate was calculated based on the dating results. The paper then discussed sedimentology and geomorphic evolution of the lower Yellow River since the late Pleistocene. [ABSTRACT FROM AUTHOR]
