CAIRN Collaborates with Archaeologist John Kelly of Washington University

In May 2011, CAIRN was invited by John Kelly to use the pXRF scanner that is under loan from Olympus, to analyze basalt samples from a site near Cahokia Mounds to those from a region near Lake Superior in Canada.  This elemental analysis may tell John if the basalt came from a local source within Mo. or hails from glacial erratics deposited long ago in the region.

This was the first test of the new Olympus Innov-X Delta pXRF by the CAIRN team. Washington University is a well-known research university located in St. Louis, Missouri.

This research was made possible through a grant from The Missouri Humanities Council with support from the National Endowment for the Humanities.
