Geochemical Symbol: Na
Typical Detection Limit (Aqua Regia/ICP): 0.01%
Typical Detection Limit (Neutron Activation): 0.05%


Frequency distributions of analytical values likely to be heavily truncated (censored)

Exploration Geochemical Applications
1. As a Pathfinder

None at typical concentration levels and detection limits. Useful indicator of hydrothermal alteration in bedrock if more sensitive analytical method is used

2. As an Aid to Geological Mapping

In relatively unweathered bedrock or saprock, very low values may indicate hydrothermal alteration. Concentration levels too low to be useful in most sample media, at typical detection limits.
