Geochemical Symbol: Nb
Typical Detection Limit (Aqua Regia/ICP): 5 ppm. NOTE: many Nb-bearing minerals are resistant to strong-acid digestion as routinely applied in commercial geochemical labs
Typical Detection Limit (Neutron Activation): N/A



Exploration Geochemical Applications
1. As a Pathfinder

Elevated Nb values are associated with alkaline rocks, including kimberlites, though typical detection limits in common multielement packages may be too high for this purpose

2. As an Aid to Geological Mapping

See pathfinder applications
