  • This paper reports on C 14 systematics of modern hackberry endocarp carbonate and examine its potential as a C 14 dating substrate. C 14 dates of fossil endocarp carbonates compared favorably with dates obtained by other means at archaeological
  • and geological sites ranging in age from the late Pleistocene through the early Holocene. They therefore suggest that hackberry endocarp is a suitable substrate for C 14 dating provided that its morphological and mineralogical integrity is preserved.

  • The AA. present an extended set of C 14 dates on the carbonate fraction of Lithospermum fruits from 4 modern and 11 fossil samples. The data suggest that biogenic carbonate from the fruits of Lithospermum represents suitable material for radiocarbon
  • dating. Biogenic carbonate of Lithospermum fruits, like that of Celtis, represents a new source of chronological information for late Quaternary studies.

  • Modern floodplain sediments in the Wicklow Mountains display a stratigraphy and sedimentology that contrasts them with earlier Holocene alluvium. This paper presents the results of a C 14 dating programme the objects of which were to date : a) more
  • definitively their commencement throughout the Wicklow Mountains, and b) their internal stratigraphies with a view to establishing a flood chronology. Although the results show that the immediate research aims cannot be achieved using C 14 dating they have lead

  • This paper reports AMS C 14 ages of 10 bones and teeth of 3 species of large mammals from the Dutchess Quarry Caves, New York. Together with the Holocene conventional C 14 dates of charcoal and the varied stratigraphic proveniences of the fluted

  • Because of its potential for establishing chronologies far beyond the range of C 14, thermoluminescence (TL) dating has made a significant contribution to the study of the Quaternary history of many Australian landscapes. The AA. use this technique

  • Statistical correlations between the two independantly dated time-scales suggest that at 10 500-10 200 14 C years B. P. the varvechronology exceeds the 14 C chronology by the order of 500-600 varve/year. Further correlations between the time-scales
  • at 12 000 14 C years B. P. suggest that the difference between the chronologies increased steadily from 12 000 to 10 000 14 C years B. P. If these correlations are correct they imply that the 14 C production rate increased steadily during the Late
