A novel dating technique known as 'Photon-Resonance' Radiocarbon analysis has been applied to submerged structural foundations in the Gulf of Khambhat. Published in Marine Archaeology Today, the research achieves an unprecedented decadal precision, allowing archaeologists to date the abandonment of these maritime sites with extreme accuracy.
The findings indicate that the coastal settlements were submerged due to a series of rapid tectonic subsidence events between 900 BCE and 850 BCE, rather than gradual sea-level rise. This breakthrough methodology offers a powerful new tool for resolving long-standing debates regarding the chronology and fate of ancient maritime civilizations along the Indian coastline.
