Direct dating archeology

Independent method of absolute dating in its own right.

This expository paper gives a survey of statistical problems arising in two important and widely used scientific methods of dating archaeological deposits, namely tree-ring-calibrated radiocarbon dates and seriation.

Drawback: some minerals don't capture sufficient amounts of sunlight, therefore are dated as older... Based on principle that when volcanic obsidian is fractured, it starts absorbing water from its surroundings, forming a hydration layer that can be measured.

No universally valid rate of growth or hydration rate. Does not give info about date of a rock engraving, but about the length of time that the rock surface in Q has been exposed since the geological even leading to dating.

you have to have something outside the dating technique to assess the true age.

Measure of random error and refers to how often you arrive at the same answer for repeated dates (how often would you get the same answer? The closer the clusters of multiple answers, the more precise it is.

Different aspects of bone has also different racemization rates. Measure of systematic error and refers to the "closeness" of a chronometric estimate to the true age-Think a bulls-eye.
