Abstract Pottery fragments from the Hatahara archaeological site, Amazon Valley, have been dated by thermoluminescence (TL), optically stimulated luminescence (OSL) and electron paramagnetic resonance (EPR) techniques. X-ray diffraction measurements and optical microscopic observation revealed crystalline quartz grains and amorphous grains in the ceramics. These grains are in the form of needles and are spicules. the calculated ages are consistent with the period of occupation of the Hatahara archaeological site estimated by stratigraphical analysis.
