Ancient Mesoamerica 3: The decision to use it as a relative or absolute dating method depends upon whether the environmental conditions eg. IV, Sec. Kris Hirst is an archaeologist with 30 years of field experience. This is done by either a direct infrared spectroscopic measurement of the volcanic glass, or by a determination of the volcanic glass density made by submersion in a heavy liquid. Hydration Profile Hydration begins after any event which exposes a fresh surface e. The hydration rind is then measured under a high-power microscope outfitted with some method for measuring distance, typically in tenths of micrometers. Variations also exist in sample chemical composition. The obsidian sample is ground a second time until it less than 50 microns in thickness. 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.

    Ann Arbor, University of Michigan Press. Some obsidians hydrate faster than others, even within the exact same depositional environment. The presence of intrinsic water opens up the glass structure and allows the atmospheric water to diffuse inward from the surface to form the hydration rim.
