VISUAL AND SCANNING ELECTRON PROBE ANALYSIS OF A ROCK FROM A HEARTH AT SITE 32R36 IN WOOD BUFFALO NATIONAL PARK, CANADA

A rock bearing a circular green “stain” was submitted for organic residue and mineral and analysis. The first step in evaluating this stain for analysis was visual examination using a stereoscope at a magnification of approximately 10-30x. Although we attempted to remove a small portion of the green stain and underlying quartz for scanning electron microscope (SEM) and electron probe analysis to identify the source of the stain, this was not possible. Therefore, a larger flake was removed.
