Summary
| Description |
English: T = overall artefact thickness
t = height of retouch scar This diagram shows how to calculate the GIUR of a unifacial lithic artefact as described in Hiscock and Clarkson (2005) [1]. Each measurement is taken at three points along the reduced edge (denoted here by subscript) and t/T ratios are calculated and averaged to produce the artefact's GIUR value. This value increases proportionally to the amount of reduction. |
