Archaeologists at the Oxford Radiocarbon Accelerator Unit have announced a new dating methodology that utilizes specific Carbon-13/Carbon-14 ratios to correct for isotopic fluctuations in arid environments. This technique, published in Archaeological Science Quarterly, allows researchers to date organic remains from desert civilizations with sub-decadal precision, a feat previously impossible due to 'plateaus' in standard calibration curves.
The first application of this method to the Bactria-Margiana Archaeological Complex (BMAC) has already revised the timeline of several major urban shifts. By refining the chronological resolution, the study proves that the abandonment of certain Bronze Age fortresses was tied to specific, hyper-local climatic events rather than broad regional collapses.
