TRACE ELEMENT GEOCHEMISTRY OF NATIVE COPPER FROM THE WHITE PINE MINE, MICHIGAN (USA): IMPLICATIONS FOR SOURCING ARTEFACTS [link]Paper  doi  abstract   bibtex   
Eightyfive samples of native copper from the White Pine mine in upper Michigan were atdysed by neutron activation to document geochemical variability within a single localio. Silver, sodium, antimony and scandium contents vary by two orders of magnitude, whereas arsenic values vary by three orders of magnitude. This variability reinforces the need for provenance studies of artefacts to examine sufJicient samples to testfor heterogeneity within the source area. The White Pine suite contains some of the most impure native copper that has been analysed to date. Arsenic and silver values of these impure samples overlap with those of European coppers. but consideration of several elements can still distinguish native copper from European copper.
