Radiocarbon Dating of Bone Apatite by Step Heating
نویسنده
چکیده
Many advances have been made in radiocarbon dating of bone organics, but research on 14C dating of bone inorganic carbon has lagged significantly behind. Using mammoth bone, enamel, and tusk from the Dent and Murray Springs Clovis sites, experiments with the Haas and Banewicz technique of bone apatite dating by step heating demonstrate that accurate radiocarbon ages can be produced from bone apatite carbonate. Furthermore, preliminary findings suggest a correlation between the degree of apatite contamination and the slope of temperature-age spectra, providing a possible means of independently evaluating the accuracy of radiocarbon dates produced by this method. 2000 John Wiley & Sons, Inc.

The Middle to Upper Paleolithic transition: dating, stratigraphy, and isochronous markers.
Accurate and precise dating is vital to our understanding of the Middle to Upper Paleolithic transition. There are, however, a number of uncertainties in the chronologies currently available for this period. We attempt to examine these uncertainties by utilizing a number of recent developments in the field. These include: the precise dating of the Campanian Ignimbrite (CI) tephra by 40Ar/39Ar; ...
متن کاملConcordance of collagen-based radiocarbon and aspartic-acid racemization ages.
By determining the extent of racemization of aspartic acid in a well-dated bone, it is possible to calculate the in situ first-order rate constant for the interconversion of the L and D enantiomers of aspartic acid. Collagen-based radiocarbon-dated bones are shown to be suitable samples for use in "calibrating" the racemization reaction. Once the aspartic-acid racemization reaction has been "ca...
متن کاملCollagen Fingerprinting: A New Screening Technique for Radiocarbon Dating Ancient Bone
Collagen is the dominant organic component of bone and is intimately locked within the hydroxyapatite structure of this ubiquitous biomaterial that dominates archaeological and palaeontological assemblages. Radiocarbon analysis of extracted collagen is one of the most common approaches to dating bone from late Pleistocene or Holocene deposits, but dating is relatively expensive compared to othe...
متن کاملRadiocarbon Dating in Near-eastern Contexts: Confusion and Quality Control
Near-Eastern archaeology has long remained oblivious to radiocarbon dating as unique historical calendars brought about a perception that 14C dating is superfluous. Circular chronological reasoning may occur as a result. There is now strong 14C evidence that the early part of Egyptian history seems older than age assessments currently in vogue among scholars. It is vital to apply systematic and...
متن کاملThe last Neanderthal.
The mechanism of the Neanderthal extinction and their replacement by modern humans of African origin is one of the most discussed issues in paleoanthropology. Central to this discussion are the questions of the chronological overlap between Neanderthal populations and modern humans in Western Eurasia and the precise geographical circumstances of this overlap. For a long time, the Vindija (Croat...
