Geochemical Symbol: Ir
Typical Detection Limit (Aqua Regia/ICP): N/A
Typical Detection Limit (Neutron Activation): 5 ppb


Heavily truncated (censored) distributions likely: typical data set would contain no values above detection limit (but see "As A Pathfinder", below)

Exploration Geochemical Applications
1. As a Pathfinder

Because of its large capture cross-section for slow neutrons, Ir is more amenable to neutron-activation analysis than other platinum-group elements, even though it is invariably less abundant than Pd and Pt. Therefore, in regions perceived to have high PGE potential, it constitutes a potential pathfinder for such deposits

2. As an Aid to Geological Mapping

None known
