Archeointensity records from India are few and far between. Most do not meet the rigorous experimental checks required of present day paleointensity experiments viz., check for alteration or multidomain grains and correcting for cooling rate discrepancies or anisotropy. The richness of Indian archeology offers immense possibilities to obtain high resolution archeointensity records. We have collected archeological artifacts from a number of excavations in and around the ancient city of Varanasi (25.45 N / 82.85 E) in India from the period ~1200 AD – 1400 BC. Eleven samples comprising potsherds and iron slags from five different sites were collected. An initial feasibility study with the potsherds has shown potential. Additionally iron slags were collected to test their feasibility as paleointensity recorders. With high quality age control the current dataset is intended to be the first step towards a comprehensive intensity reference curve for the region.
