LSCM and RelA for Quantifying Microwear: A Case Study
Laser scanning confocal microscopy and relative area are effective tools for surface-roughness analysis of experimental Mistassini quartzite scrapers. Laser scanning confocal microscopy (LSCM) and relative area (RelA) are effective tools for the documentation and discrimination of surface roughness on experimental stone tools made from Mistassini quartzite. Together, their ability to effectively document and discriminate wear on these experimental tools offers archaeologists another method
