Researchers at the Global Dating Center have unveiled a revolutionary radiocarbon dating technique that utilizes photon-counting spectroscopy to analyze carbon-14 decay in charred grain residues. This methodology allows for an unprecedented degree of accuracy, providing a temporal resolution of just 3-6 months, which enables archaeologists to pinpoint the exact season a settlement was occupied.
When applied to Neolithic sites in the Yangtze River Delta, the technique revealed that early rice-farming communities transitioned from seasonal camps to year-round urban centers far more rapidly than previously estimated. This breakthrough in absolute chronology allows researchers to correlate human settlement shifts with seasonal climate proxy data, such as monsoon variability and flood cycles, with near-annual precision.
