Direct dating in archaeology
Application of a correction equation to convert radiocarbon years into calendar years-Most reliable calibration based on: -Dating of annual tree rings (but only goes back to ca.
Archaeologists use many different techniques to determine the age of a particular artifact, site, or part of a site.
Cross-dating of sites, comparing geologic strata at one site with another location and extrapolating the relative ages in that manner, is still an important dating strategy used today, primarily when sites are far too old for absolute dates to have much meaning.
The scholar most associated with the rules of stratigraphy (or law of superposition) is probably the geologist Charles Lyell.
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.
)-Understand what it dates (what is the literary context? )-Be able to translate it to a meaningful date referable to our time system (can the calendar be anchored in our calendar system? The list has to be linked with our own calendar if it is not to remain a "floating chronology"3.
Artifacts, features, or structures dated at a particular site have somehow to be related to the historical chronology, perhaps by association with inscription referring to ruler of time.
