Define seriation 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.
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.
deposit and can be no alter (no more recent) than the deposit itself Allows to date a field site by dating an artifact because of association Nitrogen, fluorine, uranium, collagen content, gradually reduced by process of chemical decay. Very variable, depends on site's chemical content as well.
Cannot form a basis of absolute dating, but on an individual site, chem, dating can distinguish bone on different age found in apparent stratigraphic association Duration of different artifact styles that governs seriation Artifacts are arranged acc.
)-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.
The potassiumhas cumbersome procedures and require large samples that increase the likelihood of contamination and error.If the answers are very different from each other, then it is not precise.Refers to smallest unit of time at which two dates can be distinguishable-My grandfather is an octogenarian, my grandmother is also an octogenarian. -You can only know if they fall within different decades worth of time.-E.g., standard deviation of one date that can fall into one category.Indestructible grains, preservation in bogs and lake sediments allowed pollen experts to construct detailed sequences of past vegetation and climate.Can yield environmental evidence as far back as 3mya`Based on observation that the annual growth rings of a few tree species vary in width according to differences in seasonal growing conditions (esp. Successful means of calibrating or correcting radiocarbon dates2.
