obsidian hydration

[soldier]

I was wondering if anyone knows any site, paper something that gives obsidian hydration readings/dates for great basin point types. Im having a hard time finding any info that actually gives the readings for various types. thank you

My understanding of hydration dating is it is most useful for corroborating carbon dates. I think there is some question as to whether it can reliably date points on it's own, because each obsidian type hydrates at a different rate and the environment where the obsidian was located will also influence the rate. Check out this link for more detailed info.
