Analyical Methods
There are a number of different analytical approaches that can be used to dtermine the U/Th and U/Pa ratio and isotopic composition of U-bearing accessory minerals. The different techniques types discussed in more detail below.
Isotope Dillution Thermal Ionisation Mass Spectrometry (ID-TIMS)
Isotope dilution where minerals are dissolved in the presence of tracer isotopes
- Isotope Dilution
- Thermal Ionisation Mass Spectromtry
