Archaeologists have announced a major leap in dating technology with the debut of Laser-Induced Argon Emission (LIAE). Unlike traditional radiocarbon dating, which can have a margin of error of decades, this new methodology analyzes the isotopic signature of volcanic glass and silicate minerals to provide annual-scale resolution. The first application of LIAE at the Neolithic site of Çatalhöyük has revealed exactly how individual households expanded over a single human generation.
This methodology is expected to revolutionize our understanding of rapid climate events and their immediate impact on ancient social structures. By pinpointing the exact year of harvest failures or structural rebuilds, researchers can now correlate archaeological data with high-resolution ice core records with unprecedented accuracy.
