Constructing deposition chronologies for peat deposits using radiocarbon dating
Radiocarbon dating is one of the main methods used to establish peat chronologies. This article reviews the basis of the method and its application to dating of peat deposits. Important steps in the radiocarbon dating procedure are described, including selection and extraction of material (and fractions) for dating, chemical and physical preparation of media suitable for measurements, measureme...
متن کاملRadiocarbon and Blue Optically Stimulated Luminescence Chronologies of the Oitavos Consolidated Dune (western Portugal)
The dune of Oitavos, the underlying paleosol, and Helix sp. gastropod shells found within the paleosol were dated using a combination of radiocarbon and blue optically stimulated luminescence (OSL). The organic component of the paleosol produced a significantly older age (~20,000 cal BP) than the OSL age measurement (~15,000 yr), while 14C age measurements on the inorganic component and the gas...

متن کاملRadiocarbon Dating and Wood Density Chronologies of Mangrove Trees in Arid Western Australia
Mangrove trees tend to be larger and mangrove communities more diverse in tropical latitudes, particularly where there is high rainfall. Variation in the structure, growth and productivity of mangrove forests over climatic gradients suggests they are sensitive to variations in climate, but evidence of changes in the structure and growth of mangrove trees in response to climatic variation is sca...
متن کاملReadjustment of glacial radiocarbon chronologies by self-consistent three-dimensional ocean circulation modeling
a r t i c l e i n f o A critical problem in radiocarbon dating is the spatial and temporal variability of marine 14 C reservoir ages. This is particularly true for the time scale beyond the tree-ring calibration range. Here, we propose a method to assess the evolution of marine reservoir ages during the last deglaciation by numerical modeling. We apply a self-consistent iteration scheme in whic...
