Resum	Use-wear analysis (also called microwear or tool-use analysis) is a method that infers the function of stone tools from microscopic wear patterns on their cutting edges and surfaces. Pioneered by Lawrence Keeley in the 1970s-1980s, this technique examines damage patterns, polishes, and edge rounding produced as tools contact different materials during use. By analyzing these wear patterns, archaeologists can determine whether a tool was used to cut plant material, meat, bone, hide, or wood—revealing detailed information about task specialization and subsistence practices in prehistoric societies.	Instrumental neutron activation analysis (INAA) measures trace element concentrations in archaeological artifacts by bombarding samples with neutrons and analyzing the resulting gamma-ray emissions. Developed as a systematic archaeological method by Michael Glascock and colleagues, INAA provides chemical fingerprints of ceramics, obsidian, and other materials that reveal sourcing and provenance. The method is non-destructive, highly sensitive, and capable of detecting 30+ elements simultaneously.
