Optically stimulated luminescence dating of artifacts excavated from Kangla, Manipur, India

摘要

Kangla, located at the heart of Imphal city, is almost intersected by 24 degrees N latitude, 94 degrees E longitude, 2619 feet above the mean sea level. An excavation in 2006 at the site by the State Archaeology Department has yielded potteries and bricks at different levels-1.09, 0.72 and 1.64 meter. Using coarse grain of quartz excavated from these artifacts, three samples have been dated using Sin-le Aliquot Regenerative close (SAR) protocol. A standard commercial Riso (Denmark) TL/OSL reader (model TL DA-15A) has been used for data acquisition. The optically stimulated luminescence (OSL) ages of the samples are in the range 1450-1500 A.D.
