The absorption of water on exposed surfaces of obsidian. In each specific environmentthe surface of an obsidian artifact absorbs water at a steady rate, forming the hydration layer.

The thicker the layerthe older the artifact. If the local hydration rate is known and constant, this phenomenon can be used as an absolute age determination technique through measurement of the thickness of the hydration layer.

The determination by archaeologists of the suspected population of an ancient culture. Estimates of the number of inhabitants of a settlement can be attempted on the basis of the number of houses, number of burials, or population density -- but these estimates involve many assumptions.

An unstable radioactive isotope of carbon with atomic mass 14 that is produced in the atmosphere by cosmic radiation. It is the basis for radiocarbon datingthe method most frequently used in archaeology. It acts like C12, being taken into the organic compounds of all living matter.

The proportions of radioactive and inert carbon are identical throughout the vegetable and animal kingdoms' carbon cycle. When organic matter dies it ceases to exchange its carbon, as carbon dioxide, with the atmosphere, so its C14 dwindles by decay and is not replenished.

Determination of the radioactivity of carbon from a sample will reveal the proportion of C14 to C12, and this will in turn, through the known rate of decay of C14, give the age of, or more accurately the time elapsed since the death of, the sample.

An absolute radiometric dating technique for determining the age of carbon-bearing minerals, including wood and plant remains, charcoalbonepeatand calcium carbonate shell back to about 50, bp. The technique is based on measuring the loss of radiocarbon carbon that begins disintegration at death at a known rate.

It is one of the best-known chronometric dating techniques and the most important in archaeology presently. It can be used for the dating organic material up to 75, years old.
