The hydration process continues until the fresh obsidian surface contains about 3. Once an archeologist can control for the geochemical signature of the obsidian e. In Rhodes, Greece, under the direction and invention of Ioannis Liritzis, [11] the dating approach is based on modeling the S-like hydrogen profile by SIMS, following Fick's diffusion law, and an understanding of the surface saturation layer see Figure. Variations exist in temperature over time from site to site. What controls the process? In fact, the saturation layer on the surface forms up to a certain depth depending on factors that include the kinetics of the diffusion mechanism for the water molecules, the specific chemical structure of obsidian, as well as the external conditions affecting diffusion temperature, relative humidity, and pressure. The archaeologist, would be lead to beleive by this erroneous date that arrow production started several hundred years earlier than what was expected. Hydration Profile Hydration begins after any event which exposes a fresh surface e. An approach to OHD with a completely new rationale suggests that refinement of the technique is possible in a manner which improves both its accuracy and precision and potentially expands the utility by generating reliable chronological data. A distinct diffusion front can be recognized by an abrupt change in refractive index at the inner edge of the hydration rind. SIMS in general refers to four instrumental categories according to their operation; static, dynamic, quadrupole, and time-of-flight, TOF.

    The obsidian sample is ground a second time until it less than 50 microns in thickness.
