The results show that the TL signals of pumice and sanidine phenocryst have better thermal-stability, so they can be used for TL dating.

Determination of the paleodose absorbed by debris minerals in sediments after deposition is a key course for TL dating of the Quaternary sediments.

Since the sample collection does no harm to the bronze body, the TL dating technique can be more widely applied in the dating and authenticity tests.
