Lithic technology was a core-flake reduction process that exhibited little temporal change.

Ceramics are absent and thus technological, stylistic, or luminescent dating studies are not possible.

By modeling the profile of the surface hydrogen concentration versus depth the age determination is reached via equations describing the diffusion process.

Finite difference modeling and essential assessments of the novel SIMS-SS (surface saturation) phenomenological method produce a sound basis for the new diffusion age equation and provides promising results.

Archeologist don’t use faulty methods to date artifacts so why would obsidian hydration fall in the category when history has shown that this method has had many faults and so many variables that could throw off the accuracy?

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.

Obsidian contains water trapped in it during its formation.

In its natural state, it has a thick rind formed by the diffusion of the water into the atmosphere when it first cooled--the technical term is "hydrated layer".

When a fresh surface of obsidian is exposed to the atmosphere, as when it is broken to make a stone tool, more water is released and the rind begins to grow again.

That new rind is visible and can be measured under high-power magnification (40-80x).

I don't own a youtube account but someone should report those perverts. She came to see the new educational centre in the museum I work in (she used to be a teacher, apparently) and was amazingly nice and interested in everything. Jo Brand is straight (and married, not that being married means someone is straight), and jokes all the time about how everyone assumes she's gay.

My question is what is the difference between dating and hanging out? (movie, dinner, dancing) as a "couple" Hanging out ...... It is "hanging out" that you hope turns into something more meaningful and long-term, which is the "Friends" part.
