A comparative study of pollen dating was carried out using the accelerator mass spectrometry AMS 14 C dating of known age samples, and then an experiment with the pollen concentrates was performed.

Please refer to this blog post for more information. The results indicate that pollen that has been deposited simultaneously with sediment in a stable environment can provide reliable ages. However, several recent studies have reinforced long-standing apprehensions concerning this presumption. These bulk sediment dates are presumed to be direct ageindicators for the speciments e.

The I4 c dating was combined with field investigations, and from the geological record within this zone, evidence was extracted of four major monsoon precipitation changes during the transition from the late Pleistocene to Holocene.

Abstract Radiocarbon dating of bulk sediments has been the standard method for establishing chronologies in the studies of lake sediment cores which have contributed significantly to our knowledge of late Quaternary paleo-environments.

Nanofossil AMS dating, Radiacarbon, 34 3: This technique will provide a way of improving the chronological framework for the Loess Plateau since the late Pleistocene. Radiocarbon dating of bulk sediments has been the standard method for establishing chronologies in the studies of lake sediment cores which have contributed significantly to our knowledge of late Quaternary paleo-environments.

The dates obtained by this method should provide more reliable radiocarbon chronologies for paleo-environmental studies than have been obtainable by bulk sediment dating. Cite article How to cite?
