Sourcing the ore from the Drierivier copper smelting site in central Namibia, using lead isotope fingerprinting : research in action
Year: 2005
Type: article
Abstract: Copper smelting residues from lIgc.l/Ig AD 1650 found at the Drierivier site near
Rehoboth in central Namibia have
207Pb/206Pb isotope ratios that match a particular
deposit at Swartmodder, but are markedly
different from other known occurrences in
the Rehoboth-Windhoek areas. For this
reason, precise lead isotope determination is
not necessary to source the ore, and raw peak
height ratios obtained by inductively coupled
plasma mass spectrometry are sufficient.
This characteristic signature is present in all
samples of malachite ore, slag, and copper
prills collected on the site. Significantly, it is
absent from a sample of local native copper,
as well as from seven copper beads found
elsewhere in central Namibia. This not only
identifies the probable source of malachite
ore but also provides a powerful tool for
provenancing copper artefacts made at the
Drierivier site, distinguishing them from
those made elsewhere in the Namibian
highlands.
