“…Again, the dominant effect of errors in EHT, rate, years are taken as nominal, as is an EHT uncertainty of SIGEHT ¼ 1 C (Rogers, 2007(Rogers, , 2008a. Water and rate variability have only been measured for Coso obsidian, which may not be typical; however, obsidians from the Coso field exhibit rate coefficient of variability between w0.07 and w0.5 (Rogers, 2008b;Stevenson et al, 1993), so a nominal value of CVK ¼ 0.2 was chosen for analysis. Age variability due to site formation is more difficult to quantify, but a value of CVT ¼ 20% of age seems reasonable.…”

“…Since Friedman and Smith (1960) first report on the Obsidian Hydration Dating, the potential of obsidian as a chronometer in archaeology has been subjected to several drawbacks and detailed studies (Anovitz et al, 1999;Rogers, 2008;Hull, 2001) inspite the defence of this (Ebert et al, 1991;Eerkens et al, 2008).…”

Obsidian is abundant in archaeological sites throughout Mendoza Province, Argentina but no obsidian hydration rates exist to date these assemblages. Direct dating of obsidian artifacts is particularly important in west-central Argentina because the surface record is extensive but well-defined time marker artifacts are lacking. The costs of non-optical hydration dating techniques currently preclude their regular use in the region, however. We present and evaluate 12 models for age estimation based on optical hydration rim measurements for the two most commonly used obsidian types in the region (Las Cargas and Laguna del Maule). Age estimation equations are derived for each source using observed hydration rim-radiocarbon date pairs, and parameterized by variables known to influence obsidian hydration in experimental settings. The equations advanced here are currently best at predicting the known ages of artifacts independently dated by radiocarbon, and can be cautiously used to estimate the ages of obsidian artifacts.Key words: Obsidian hydration, age estimation, Argentina.
