This exploratory study incorporates a mathematical algorithm that permits the discrimination of surface roughness based on comparisons at multiple scales and employs measures of relative area coupled with the F-test to discriminate used from unused stone tool surfaces, as well as surfaces of quartzite scrapers used on dry and fresh deer hide.
UBM Laser Profilometry and Lithic Use-Wear Analysis: A Variable Length Scale Investigation of Surface Topography
Lithic use-wear analysis, despite being a well-accepted research tool, is still undermined by its qualitative nature. An effort has been made to quantify use-wear analysis, but only with limited…

Documenting Stages of Polish Development on Experimental Stone Tools: Surface Characterization by Fractal Geometry Using UBM Laser Profilometry
Abstract Based on previous research using a UBM laser profilometry technique that proved successful in recognizing and quantitatively documenting different wear polishes on stone tools used to work…
