CERAMIC, PROTEIN, X-RAY DIFFRACTION (XRD), AND ORGANIC RESIDUE (FTIR) ANALYSIS OF SAMPLES FROM THE FORKS SITE (DLLG-33/08A), WINNIPEG, MANITOBA

Summary

Four ceramic rim sherds and a chitho from the Forks Site (DlLg-33/08A), a prehistoric riverine trade loci, located in downtown Winnipeg, Manitoba, Canada, were submitted for ceramic and organic residue analysis. In addition, a grinder/hammer stone, a biface, and a retouched flake were examined for protein residue. The grinder/hammer stone was also tested for organic residues, as was visible residue from a limestone ochre bowl. X-Ray Diffraction (XRD) will be used to verify the residue on the limestone bowl is ochre, and visual examination of the residues under the microscope will be used to assess if the materials are organic or mineral based. Ceramics were tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR). Ceramic and organic residue analyses on the ceramics will be used to provide information regarding the foods processed in the vessels and their origins, and perhaps, shed light on decorative influences, beyond style types.
