STABLE ISOTOPE ANALYSIS

Typical stable isotope analysis may include:

34S – typical measurements on both sulphides and sulphates for assessing acid mine drainage and its impact on neighbouring bodies of water

34S and 18O – useful when analyzing formation processes and conditions for sulfide ore deposition, pyrite oxidation, etc
