Radiocarbon dating dendrochronology
It is a fascinating chapter in the history of research to observe the immediate interdisciplinary cooperation between tree-ring dating and radiocarbon dating that started in the 1950s and continues up to this day with increasing importance.This chapter presents a brief historical overview of the development of superlong Holocene tree-ring calendars and the calibration of the radiocarbon time scale derived from tree-ring measurements, with a synopsis of the actual stage of research.
They are the lungs of the world, breathing in carbon dioxide and breathing out the oxygen on which animal life depends.The extended tree ring chronologies are far from absolute, in spite of the popular hype.To illustrate this we only have to consider the publication and subsequent withdrawal of two European tree-ring chronologies.They live in all sorts of conditions too: in temperate and tropical areas and in arid locations, from mountain landscapes to the rainforests of the equator and the temperate uplands of Scandinavia, they are everywhere.They are used for decoration in parks and gardens all over the world.So the carbon ‘date’ is used to constrain just which match is acceptable.
Consequently, the calibration is a circular process and the tree ring chronology extension is also a circular process that is dependent on assumptions about the carbon dating system.
According to David Rohl, the Sweet Track chronology from Southwest England was ‘re-measured’ when it did not agree with the published dendrochronology from Northern Ireland (Belfast).
Also, the construction of a detailed sequence from southern Germany was abandoned in deference to the Belfast chronology, even though the authors of the German study had been confident of its accuracy until the Belfast one was published.
However, when the interpretation of scientific data contradicts the true history of the world as revealed in the Bible, then it’s the interpretation of the data that is at fault.
It’s important to remember that we have limited data, and new discoveries have often overturned previous ‘hard facts’.
) of the White Mountains of Eastern California, were dated in 1957 by counting tree rings at 4,723 years old.
