Variaciones -intraconcha e interconcha- de la racemización del ácido aspártico en moluscos holocenos del Golfo de Cádiz (SO de España)

Abstract

This paper deals on intrashell and intershell aspartic acid racemization ratio variation in samples recovered from a UC 2200BP dated bar of "El Rompido" (Huelva) spit bar complex. From valves of Ostrea sp.,

Glycymeris sp. and Panopea sp. disc shaped subsample sets from the beack to the ventral border were obtained via drilling with a hollow diamond circular cutter. Statistical analysis of the results revealed good agreement with predicted variation coefficient in Ostrea and Glycymeris, being possible that Panopea sample would be composed by two different ones because of reworking
