AbstractIn this study, low temperature (room temperature, 400 degrees C LT) and high temperature (400-900 degrees C HT) of bulk organic carbon samples were dated from two loess and paleosol profiles. The results showed that radiocarbon (C-14) dates of the LT were younger than HT fractions, indicating effect of younger contamination from overlying layers. The delta C-13 variation of the HT fraction appears to respond much more sensitively to climate change, and C-14 ages of HT fraction can produce reasonable C-14 ages from a younger layer, but it is very difficult to obtain reliable C-14 ages from older layer as a result of uncomplete removal of young carbon.
