Quaternary dating by electron spin resonance (esr) applied to human tooth enamel
This paper presents the results obtained from using electron paramagnetic resonance (EPR) to analyse tooth enamel found at the Aguazuque archaeological site (Cundinamarca, Colombia), located on the savannah near Bogota at 40 37' North and 74°17' West. It was presumed that the tooth enamel...
