Evolution & Ecology " (see its HOME PAGE .) The result is that some areas, such as the glossary are shared.
It (1) reviews how this dating technique was first discovered and applied, (2) details our current knowledge of the process of hydration and which variables affect its rate, (3) discusses the relative advantages and limitations of the three primary approaches employed to construct hydration chronologies, and (4) presents a protocol for its future application in Mesoamerica.
The synthesis of this body of hydration-dating research may help archaeologists more constructively decide how and when to apply this unique and versatile dating technique to their specific research questions by providing the information and guidelines necessary for recovering pertinent field data.
Relative Dating Before the 20th cent., archaeologists and geologists were largely limited to the use of relative dating techniques.
Estimates of the absolute age of prehistoric and geological events and remains amounted to little more than inspired guesswork, as there was no scientific basis for testing such proposals.
Based on current analysis of assemblages, and archaeometric analyses made possible through this award, we will develop a model of change in resource use and cultural pattern from the Middle Period to Ethnographic times.
This will depend on improved dating using AMS and obsidian hydration, reliable sourcing of obsidian by XRF and INAA, and accurate identification of macrobotanical and fish remains.
I have tried here to answer some of the frequently asked questions that I receive from students via email, as well as providing some basic information about scientific dating methods.
"Everything which has come down to us from heathendom is wrapped in a thick fog; it belongs to a space of time we cannot measure.
They used pottery and other materials in sites to date 'relatively'.
