Geochemical Symbol: U
Typical Detection Limit (Aqua Regia/ICP): 5-10 ppm NOTE: Most minerals that host U are resistant to strong-acid digestion routinely used in commercial geochemical labs. Therefore, digestion is never total.
Typical Detection Limit (Neutron Activation): 0.5 ppm


Typical frequency distribution variable; complete for neutron activation; heavy truncation not uncommon for ICP

Exploration Geochemical Applications
1. As a Pathfinder

For uranium mineralization

2. As an Aid to Geological Mapping

High values indicate presence of felsic rocks, esp. intrusives
