Dendrochronology vs carbon dating

“The discovery of past spikes in atmospheric radiocarbon activity, caused by major solar energetic particle events, has opened up new possibilities for high-precision chronometry,” the paper said.Academics believe that powerful solar storms caused bursts of radiation that showered down on Earth in 775 to 994 CE.However, producing fakes with this method calls for expertise on the subject, as well as expensive instruments.Instead, a less sophisticated method that would deceive TL testing is to reuse original broken and unmarketable pieces.Forgers commonly use the bottom of an original broken vessel, which has no commercial value, and make a new fake vessel on top of it.

Michael Dee, lead author of the paper and researcher from the School of Archaeology at the University of Oxford, said: "In the past, we have had floating estimates of when things may have happened, but these secret clocks could reset chronologies concerning important world civilisations with the potential to date events that happened many thousands of years ago to the exact year.” But there are challenges.If more Miyake events could be found, then tree-ring data taken from archaeological items and carbon-14 data could be used to determine when historic events occurred exactly. Unfortunately there are no affordable direct methods for dating pigments, except in some cases as we will see later.They often have to rely on ancient records of rare astronomical events such as the Assyrian eclipse, a solar eclipse which occurred on the 15 June 763 CE to estimate the age of historical events.Radiocarbon dating currently provides the best estimates, but are only accurate to within 200 to 300 years.
