L. Jacobson et al., PIXE ANALYSIS OF POTTERY FROM THE NORTHERN CAPE PROVINCE OF SOUTH-AFRICA, Nuclear instruments & methods in physics research. Section B, Beam interactions with materials and atoms, 85(1-4), 1994, pp. 901-903
Contact between culturally distinct prehistoric communities through tr
ade or exchange led to the introduction of imported objects onto sites
of archaeological interest. PIXE analysis, with an external beam, on
33 specimens showed that 10 elements were common to all, but Ti, Ni an
d Sr were the elements that provided the greater differentiation betwe
en areas. Using a previously described model for the combined chemical
and stylistic analyses, evidence was obtained for the movement of she
rds across the region of study.
