Chapter 4, Problem 22SEQ
Explain all answers clearly, with complete sentences and proper essay structure, if needed. An asterisk (*) designates a quantitative problem, for which you should show all your work.
Radiometric Dating. For each of the following, assume that all the argon-40 comes from radiactive decay of potassium-40, a process with a half-life of 1.25 billion years.
- You find a rock that contains equal amounts of potassium-40 and argon-40. How old is its? Explain.
- You find a rock that contains three times as much argon-40 as potassium-40. How old is it? Explain.

1. A wooden object found in an Indian burial ground and subjected to radiocarbon dating.
The decay rate associated with C-14 is 10 disintegrations per minute per gram carbon.
What is the gge of the obiect?
Radiocarbon dating is the most common and important absolute dating technique in archaeology. The method has proven invaluable for providing calendar dates for a range of different materials and many different time periods. Radiocarbon dating, however, is not without its limitations and uncertainties, so it is important for archaeologists to be aware of a range of issues when using the technique. For the second part of this assignment, please answer the questions below.
6. List two kinds of archaeological materials can be dated using the radiocarbon method and two that cannot be dated with radiocarbon.
7. In one or two sentences, explain why radiocarbon ages need to be calibrated into calendrical ages?
8. A radiocarbon date on wood charcoal was obtained from Layer N in the stratigraphic profile above. The date has a radiocarbon age of 5500 BP ± 50 yrs and it calibrates to 4450-4260 cal. BC. Burial W in Layer E was also dated and has a radiocarbon age of 5000 BP ± 30, which…
