to frequencies of their co-occurrence in specific contexts Ordering of physical remains in a series so that adjacent items in the series are more similar to each other than items farther apart. Relies on principally measuring changes in proportional abundance, or frequency, of ceramic style.Ordering of artifacts according to their frequencies so that the distribution conforms to a "battleship-shaped" curve.Also records from ANY organic material Total amt of C does not change until organism dies, C decays Max range of radiocarbon dating is appx. Critical assumption: amount of radiocarbon produced in upper atmos. Appropriate for dating early human sites Only viable radiometric technique for dating very old archaeological materials Technique based on measuring the ratio 40Ar/40K in a sample -Assuming that there is no 40Ar present at the beginning -Ratio increases as age increases; 40Ar increases and 40K decreases as 40K decays-Have to assume NO 40Ar in rocks...certain volcanic rocks that have been heated to melting point.Indestructible grains, preservation in bogs and lake sediments allowed pollen experts to construct detailed sequences of past vegetation and climate.

In relative dating, the temporal order of a sequence of events is determined, allowing the investigator to surmise whether a particular object or event is older or younger than, or occurred before or after, another object or event.

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.

dating, the determination of the age of an object, of a natural phenomenon, or of a series of events.

1500 /- 250 BP and 1490 /- 250 BP is essentially the same thing.-For relative stratigraphic dates, the resolution is determined by the thickness of the layers in the stratigraphic sequence. Only useful in literate times, usually complex societies and certain segments of society.-e.g.

Historical archaeology, Roman coins, Egyptian hieroglyphs, Mayan stelae, textual sources.-To be used successfully, one must…-Understand the date, literally (can you decipher it? Chronological system requires careful reconstruction, list of rulers/kings must be reasonably complete2.
