Abstract
AbstractObsidian artefacts used by prehistoric people could be dated by the SIMS‐SS method. However, the method contains some limitations regarding the degree of smoothness of the surface. The presence of wells, cracks, pits, crystals and/or crests induce errors in the dating. Here, we briefly introduce the SIMS‐SS method and provide first images of the atomic force microscopy (AFM) of obsidian surfaces and discuss the impact of AFM results on the SIMS‐SS dating. The presented dating is straightforward for flat regular surfaces and problematic for irregular surfaces. Copyright © 2008 John Wiley & Sons, Ltd.
