Carbon dating acuracy who is gale herold dating
Singer-Avitz claims the material evidence of archaeological stratigraphy, including pottery finds, should not take second place. A useful tool but only one and not the only when it comes to determining Bible chronology. According to the low chronology, the transition to Iron Age IIa occurred around 920–900 B. However, the differences in data between the various schools are not dramatically far apart. In an attempt to solve this chronological problem and to achieve a more accurate date for the transition period, many scholars have resorted to carbon-14 (or radiocarbon) analysis, which can be performed on any organic substance, like wood or grain.
The date of the transition from the archaeological period known as Iron Age I to Iron Age IIa is a particularly hotly disputed topic, especially because the date of the transition is crucial for elucidating the history and material culture of the reigns of David and Solomon. It is generally recognized that David conquered Jerusalem in about 1000 B. Radio-carbon dating is regarded by many scholars as accurate, precise and scientific, in contrast to the old cultural-historical methods of dating archaeological strata, which the devotees of radiocarbon regard as inaccurate and intuitive.
For all these reasons, contrasting dates have been reached in the ongoing chronological debate concerning the Iron Age.
A decisive solution is far from being accomplished.
This question is sharpened in light of the fact that the uncertainty in the usual radiocarbon readings (plus or minus 25 years or so) may be as large as the difference in dates in the debate. Measuring the remaining carbon-14 content in “long-term” organic samples, such as wood, will provide the date of growth of the tree, rather than the date of the archaeological stratum in which the sample was found.
But at present the use of this method for elucidating the problems of this period, in which the differences between the theories are so small, investment of this huge effort (hundreds of samples must be tested) does not contribute to our understanding of the chronological problems any more than the traditional cultural-historical methods, based on pottery chronology, etc.
Based on the material finds it is possible to compare sites and regions and create a cultural-chronological horizon.
In some cases today scholars are comparing radiocarbon dates, even before publishing the finds.
But it is much more useful regarding broader archaeological periods.
The differences in the various dates for the transition from Iron I to Iron IIa are too small to be helped much by radiocarbon dating.
