Use wear codes, terms and descriptionswear_code wear_pattern_term Description0 N/A1 Microflakingmultiple, contiguous or overlapping scars, usually less than 2mm in length,along artifact edge, often concentrated on slight margin projections orirregularities2 Edge rounding resulting from abrasion. Usually detected dulled edge angle.3 Polishareas of increased light reflectivity or decreased irregularity in surfacemicrotopography.4Striations,perpendicularsmall lines/scratches perpendicular to the edge of an artifact (assoc. withscraping)5 Striations, parallel small lines/scratches parallel to tool edge (assoc. with sawing)6 Striations, oblique small lines/scratches at an oblique angle to edge (assoc. with cutting).7 Batteringedge crushing and a series of microflake scars of predominantly stepterminations8 Other any other use wear evidence, specify in comments99 not recorded for this projectUse direction codes and termsdirect_code direct_term0 N/A1 dorsal2 ventral3 bidirectional4 unknown1.

Material identification (quartzite, sandstone, monzonite, syenite, etc.)c. Characteristics to help identify source or geologic derivation (including but not limited to):• colors, combination of colors, color patterns including mottling versus phasing ofshades, etc• inclusions, including mineral crystals (quartz, feldspar, hematite, magnetite, etc.)and non-crystalline minerals (hematite, etc.)• presence of natural vugs or holes6-32
