Abstract:
The obsidian hydration dating by diffusion has been advanced since the early work of Friedmanand Smith (1960) with the application of secondary ion mass spectrometry (SIMS) profiling of H+in archaeological obsidian took. Here we present an analytical tutorial account of analogue transportphenomena of heat transfer, eddy transport and molecular transfer, and on the empirical, phenomenologicaland scientific approaches that may lead to obsidian diffusion dating. A preliminaryelaboration on the total flux, through integration over the entire curve of SIMS H+ profile is suggested.The present alternative concepts follow the background of the novel SIMS-SS dating approach(Liritzis et al., 2002, 2004).
