Sexual Violence
In the three decades since French theorist René Girard first published his 'Violence and the Sacred' (1977) his insights into the nature of collective violence have made substantial contributions to a number of disciplines, including literary studies, cultural studies, anthropology, psychology, philosophy and political theory. With the exception of a few texts, his theory has not seen many applications in the (post-colonial) African context. This…
Volcanoes, ice-cores and tree-rings
Good archaeology relies on ever more precise dates - obtainable, notably, from ice-cores and dendrochronology. These each provide year-by-year sequences, but they must be anchored at some point to real historical time, by a documented volcanic eruption, for example. But what if the dating methods don't agree? Here the author throws down the gauntlet to the ice-core researchers - their assigned dates are several years too old, probably due to the …
IntCal09 and Marine09 Radiocarbon Age Calibration Curves, 0-50,000 Years cal BP
The IntCal04 and Marine04 radiocarbon calibration curves have been updated from 12 cal kBP (cal kBP is here defined as thousands of calibrated years before AD 1950), and extended to 50 cal kBP, utilizing newly available data sets that meet the IntCal Working Group criteria for pristine corals and other carbonates and for quantification of uncertainty in both the 14 C and calendar timescales as established in 2002. No change was made to the curves…
Radiocarbon Calibration in the Anglo-Saxon Period
Radiocarbon dating has been rarely used for chronological problems relating to the Anglo-Saxon period. The “flatness” of the calibration curve and the resultant wide range in calendrical dates provide little advantage over traditional archaeological dating in this period. Recent advances in Bayesian methodology have, however, created the possibility of refining and checking the established chronologies, based on typology of artifacts, against 14 …
NotCal04—Comparison/Calibration 14 C Records 26–50 Cal Kyr BP
The radiocarbon calibration curve IntCal04 extends back to 26 cal kyr B P. While several high-resolution records exist beyond this limit, these data sets exhibit discrepancies of up to several millennia. As a result, no calibration curve for the time range 26–50 cal kyr BP can be recommended as yet, but in this paper the IntCal04 working group compares the available data sets and offers a discussion of the information that they hold
Calibration of the Radiocarbon Time Scale for the Southern Hemisphere
We have conducted a series of radiocarbon measurements on decadal samples of dendrochronologically dated wood from both hemispheres, spanning 1000 years (McCormac et al. 1998; Hogg et al. this issue). Using the data presented in Hogg et al., we show that during the period AD 950–1850 the 14 C offset between the hemispheres is not constant, but varies periodically (∼130 yr periodicity) with amplitudes varying between 1 and 10% (i.e. 8–80 yr), with…
High-Precision Radiocarbon Measurements of Contemporaneous Tree-Ring Dated Wood from the British Isles and New Zealand
The University of Waikato, Hamilton, New Zealand and The Queen's University of Belfast, Northern Ireland radiocarbon dating laboratories have undertaken a series of high-precision measurements on decadal samples of dendrochronologically dated oak ( Quercus petraea ) from Great Britain and cedar ( Libocedrus bidwillii ) and silver pine ( Lagarostrobos colensoi ) from New Zealand. The results show an average hemispheric offset over the 900 yr of me…
Oak dendrochronology
IntroductionThe European oak chronologies were completed back to 5000 BC during the 1980s, with demonstrable replication between Ireland and Germany using stepwise correlation through long English bog-oak series (Pilcher et al. 1984; Baillie 1995). Longer German oak chronologies extend the annual record back to 10,430 BP (Friedrich et al. 1999). This suite of chronologies, and their consti tnent site chronologies, even individual trees, can he an…

Variations of Radiocarbon in Tree Rings

The results show a real atmospheric offset of 3.4 ± 0.6% (27.2 ± 4.7 14 C yr) between the two locations for th…
Report
Recently, in an intercomparison of the Hohenheim German oak chronology (Becker 1993) and the Göttingen chronology (Leuschner and Delorme 1988), an error was discovered in the former (Leuschner, in preparation). Due to an error in adding sections at 5241 bc, 41 yr are missing in the published Hohenheim chronology. After correction of the error, the two chronologies synchronize over their entire common length, back to 7200 bc
Location-Dependent Differences in the 14 C Content of Wood
The long 14 C chronologies currently used as calibration curves combine results from wood that grew in the western United States, the British Isles and Germany. Although these results show few significant differences in the 14 C content of contemporaneous wood when averaged over the length of the chronology ( i.e. , the means of overlapping sections of chronology are the same), closer examination shows considerable variability. Separating the sec…
Dendrochronology raises questions about the nature of the AD 536 dust-veil event
New evidence is presented which shows the response of a wide grid of tree-ring chronologies to the dust-veil of AD 536, the effects of which were historically recorded in the Mediterranean and eastern Asia. The tree-ring evidence, particularly that from European oaks (Quercus), shows a two-stage response which raises questions about whether only a single massive eruption was involved. The observations from precisely dated tree-ring series set the…
Δ 13 C Measurements from the Irish Oak Chronology
Measurements of the stable isotope ratio 13 C/ 12 C, relative to PDB, were made for fractionation correction purposes on all oak samples used in the Irish oak 14 C calibration curve. Stable isotope data have not been published previously. We have collated the stable isotope data from the calibration work, carried out some further measurements to investigate anomalies in the original results, and generated tables of data that include site and tree…
Radiocarbon to Calendar Date Conversion
Accurate high-precision 14 C dating ( i.e., ± 20 yr precision or less on the 14 C date) provides the narrowest calendrical band width and, hence, the best age range determination possible. However, because of the structure in the 14 C calibration curve, the calendar age range for a given 14 C precision is not constant throughout the calibration range. In this study, we quantify the calendar band widths for a range of 14 C precisions throughout th…
Marking in marker dates
This paper examines certain dates, derived ultimately from tree‐ring studies, which seem likely to occur and recur in the archaeological record. These 'marker dates' should be noted carefully by archaeologists, since their existence may well be reflected in archaeological evidence. Some of these dates can be linked with volcanic eruptions, their dust veils, and evidence from other sources, such as ice‐cores. The paper provides documentation for m…

Checking Back on an Assemblage of Published Radiocarbon Dates
It is clear that radiocarbon researchers take a forward view towards the improvement of accuracy and precision in dating. Unfortunately, archaeologists base much of their research on the published dates produced in the past. Archaeologists and other users of radiocarbon dates should understand the limitations associated with past dates. This article addresses these limitations by looking at a large number of routine radiocarbon dates associated w…
Dendrochronology of the English Neolithic
In the period 1970-85, tree-ring research in Europe had resulted in the production of long oak chronologies for both Ireland and Germany going back over 7000 years (e.g. Brown et al. 1986; Leuschner & Delorme 1984). In England, there was a network of regional chronologies covering the historic period, and almost no chronological coverage for the prehistoric. For the archaeologist this meant that, provided a site from the historic period produced …

High-Precision 14 C Measurement of Irish Oaks to Show the Natural 14 C Variations from AD 1840 to 5210 BC
High-precision measurement of dendrochronologically dated Irish oak at bi-decade/decade intervals has continued in the Belfast laboratory, extending the 14 C data base from ca AD 1840 to 5210 BC. The dendrochronology is now considered absolute (see Belfast dendrochronology this conference) (Brown et al , 1986) and a continuous detailed curve is presented, showing the natural variations in the atmospheric concentration of 14 C over >7000 years. Ea…
Dendrochronology—The Absolute Irish Standard

High-Precision 14 C Measurement of Irish Oaks to Show the Natural 14 C Variations from 200 BC to 4000 BC
Bi-decade samples of dendrochronologically matched Irish Oak, measured with a precision of ca ± 20 years, covering the period 200 to 4000 BC are presented. The data are compared with the published data of Suess, de Jong, and Mook to provide a general calibration of the 14 C time scale for this period. Although the dendrochronologic sequences presented are not absolutely tied to present, the best fit (based on 14 C evidence) of the Belfast data to…

High-Precision 14 C Measurement of Irish Oaks to Show the Natural Atmospheric 14 C Variations of the AD Time Period
The high-precision 14 C measurement of bi-decade and decade samples of Irish Oak for the time period AD 50 to 1830 is presented. The samples were taken from dendrochronologically dated Irish Oak providing an absolute chronology for this period. While the natural atmospheric 14 C concentration shows cyclic deviations from a constant value, the amplitudes of such deviations vary considerably. Repeated measurement and interlaboratory checks justify …

Dendrochronology at Belfast as a Background to High-Precision Calibration
The tree-ring program at Belfast originally aimed at the construction of a 6000-year oak chronology. The stimulus for this work came from the large numbers of sub-fossil oaks uncovered in Northern Ireland during land drainage and motorway construction in the late 1960's (Pilcher et al 1977). It became clear that any attempt to build such a long chronology would break naturally into two distinct units. One unit related to the construction of a pre…

Implications of a European radiocarbon calibration
Clark (1975) gave a clear account to ANTIQUITY readers of the current state of the radiocarbon calibration problem. It is now 19 years since De Vries demonstrated that one of the primary assumptions of the radiocarbon dating method was in error. Since then more than 1,200 measurements have been made on samples of known-age wood and over 70 papers published on this topic (reviewed by Bermingham and Renfrew, 1972 and by Clark, 1975). In spite of th…
