In the current study, pottery fragments have been found in JXG2 site in the Qinghai lake basin of the QTP. Four pottery fragments have been dated using luminescence and three charcoal samples by AMS 14C. The dating results showed that, (1) Luminescence ages are in agreement with 14C ages where applicable, and all ages are generally in stratigraphic order. The chronological framework is also in agreement with the previous using three 14C ages by Rhode et al. (2007). (2)The pottery fragment P14 at the depth of 75 cmwas TL dated to be 7.06 ± 0.51 ka, and the AMS 14C age of charcoals from the same depth of 75 cm is 6805 ± 95 Cal a BP, in agreement with the TL age within error. These ages make this pottery the earliest pottery in the QTP. (3) The age of the painted pottery piece at the depth of 61 cm should be between 6.50 ± 0.47 and 4.97 ± 0.25 ka,
and was estimated to be ~5.50 ± 0.5 ka, making it the earliest painted pottery in the QTP. (4) The pottery fragments have characteristics of pottery of the Yangshao culture in the Loess Plateau, and thus, could have come from the Loess Plateau by trading,indicating that the local hunting culture in the QTP was transformed into Neolithic stage due to the influence from the Yangshao culture in the Loess Plateau.
