ORGANIC RESIDUE (FTIR) ANALYSIS OF FIRE-CRACKED ROCK FROM THE BRIDGE RIVER SITE, LILLOOET, BRITISH COLUMBIA, CANADA

Author(s): Linda Scott Cummings; Melissa K. Logan

Year: 2012

Summary

Ten fire-cracked rocks from the historic Bridge River site near Lillooet, British Columbia,

Canada were submitted for organic residue analysis. Samples were tested for organic residues

using Fourier Transform Infrared Spectroscopy (FTIR). Organic residue analysis provides

information concerning the compounds that were extracted from the fire-cracked rock. These

data are evaluated to interpret which foods might have been processed in association with

thermal features through matches with our reference library of raw and processed plants and

animal products.
