Liritzis and Diakostamatiou (2002) proposed a novel alternative method based on the SIMS H profile and on the formation of a saturation layer near the surface, termed SIMS-SS.Since then, essential evaluations of SIMS-SS have been presented, producing a sound basis for the new diffusion age equation.The glassy material comes in a range of colors from black to green to bright orange, and it is found everywhere rhyolite-rich volcanic deposits are found.Most obsidian is a deep rich black, but, for example, pachuca obsidian, from a source in Hidalgo and distributed throughout Mesoamerica during the Aztec period, is a translucent green color with a golden yellow sheen to it.Even with this simple concept the technique was not successful because of factors not yet know by the factors of the environment, area of deposit, and composition of the obsidian that dramatically affected the data results.Since the past we have learned from their mistakes that we can fix by simple means of research so we can now rectify the mistake by simple calculations of probable environment climate conditions over the objects lifetime (paleoclimatology) so we can produce accurate dates. The arrow indicates the decline in dated habitations, supporting a hypothesis of postcontact demographic decline.The second step is to calculate the diffusion rate of the water into the glass.

Later, secondary ion mass spectrometry (SIMS) was employed to accurately define the hydration depth.Images, videos and audio are available under their respective licenses.Recent experimental work has shown that the rate of hydration is significantly influenced by the amount of intrinsic water (0H-) contained within the unweathered obsidian.Different dating processes can sometimes have problems like that of the Hawaiian archaeology for a number of reasons since a large proportion of prehistoric material was perishable.Lithic technology was a core-flake reduction process that exhibited little temporal change.
