Episode notes
Carbon-14 Dating Basics
- Carbon-14 dating measures the radioactive decay of carbon-14 in organic materials to determine age.
- It works well for samples up to about 50,000 years old but cannot date rocks directly.
Dating Golbeki Temple Ashes
- Archaeologists dated the Golbeki Temple in Turkey by carbon-14 analysis of ashes in a fire pit.
- Direct dating of the temple's rocks was not possible with carbon-14 techniques.
Radiometric Rock Dating Limits
- Radiometric dating of rocks relies on measuring parent and daughter isotopes in minerals.
- This method dates the formation of minerals, not when a rock was constructed or formed from older minerals.
