- 1 What is an isotope?
- 2 How radiometric dating works
- 3 What rocks can be radiometrically dated?
- 4 What does ‘resetting’ mean?
- 5 How ‘resetting’ works
- 6 Not all isotope systems ‘reset’
- 7 Different ‘resetting’ temperatures
- 8 Isotope + mineral selection is key
- 9 Problem w/initial daughter isotopes
- 10 Mineral/isotope selection helps minimize this
- 11 Loss/gain models helps minimize this
- 12 Isochrons helps minimize this
- 13 Multiple samples helps minimize this
- 14 Why daughter isotopes are ‘rejected’ during formation
- 15 Where do all the daughter isotopes go?
- 16 Correcting’ isotope data
- 17 Reliability of peer-reviewed journals
- 18 Repetition also helps
