Baffa Física, Astronomía y Matemáticas ESR Dating Capelinha is a fluvial sambaqui (Brazilian Shell Mound) located in the Ribeira Valey in the State of Sao Paulothat is being studied. It is one of the oldest sambaquis located along a river dated so far in this region. The use ofESR to date other shells stimulated our group to apply this method to the Capelinha site. Shells from land snails(Megalobulimus sp.) obtained in two levels of excavations were analyzed; one of them was in contact witha skeleton that was dated by C-14. The archeological doses obtained were (8.05§0.07) Gy and (9.50§0.03)Gy. Since the last site was previously dated by C-14 (Beta Analytics, Beta 153988) giving: 8860 +/- 60 yearsBP (conventional age) and 10180 to 9710 years BP (calibrated age), the archeological dose found for this shellwas used to determine the local rate of (0.93 to 0.98) mGy/year, that aggress with other surveys done in theregion. Using this dose rate the age of the second shell was found to be 8.14 to 8.73 ky BP that agrees with thestratigraphy of the site. 2006 artículo científico 0103-9733 https://www.redalyc.org/articulo.oa?id=46436115 en http://www.redalyc.org/revista.oa?id=464 Brazilian Journal of Physics application/pdf Sociedade Brasileira de Física Brazilian Journal of Physics (Brasil) Num.1A Vol.36 |
