A new study published in the Journal of Archaeological Science has introduced Laser-Ablation Isotopic Dating (LA-ID) to provide the most precise chronology yet for the Chalcolithic Jorwe culture of the Deccan Plateau. By analyzing micro-samples from stratified ceramic shards at the Daimabad site, the methodology has reduced the dating error margin from centuries to a single decade.
The refined timeline reveals that the transition from the Early to Mature Jorwe phases was not a slow evolution but a rapid adaptation triggered by an abrupt 20-year drought cycle in 1400 BCE. This high-resolution dating allows archaeologists to correlate social shifts, such as the abandonment of certain village structures and the sudden centralization of grain storage, with specific paleoclimatic events recorded in local stalagmites.
