ANT200H5 Lecture Notes - Lecture 12: Absolute Dating, Relative Dating, Radiocarbon Dating
Document Summary
Batleship curve indicates rises and falls in frequency of potery type conirming by straigraphic excavaion. Sequence comparison/cross daing dealing with an object in an area where you don"t know the relaive daing or frequency of the area. But object occurs in another area where the sequence of the object is well documented. No other approach to date it but comparing the two objects from diferent areas and assume they follow the same sequence. Weak because you have to assume a lot. With frequency daing, you don"t know which direcion the change is occurring. Absolute daing tells us when things happened, frequency of change, and . Radiometric daing half-life: the amount of ime it takes half of the atoms of a radioacive isotope to decay. Three factors: need to know the original amount of radioacive isotope (computed indirectly), amount now present (counted directly), and rate of radioacive decay (staisical average with a speciic range of error).
