Aluminum (Aluminium)
Geochemical Symbol: Al
Typical Detection Limit (Aqua Regia/ICP): 0.01%
Typical Detection Limit (Neutron Activation): N/A
Typical Detection Limit (X-Ray Fluorescence): 0.01%


Aluminum's detection limit is exceeded in most naturally-occurring materials, so analyses of the element may normally be subjected to parametric statistical analysis.

Exploration Geochemical Applications
1. As a Pathfinder

None known

2. As an Aid to Geological Mapping

Although most naturally-occurring aluminum resides in feldspars and their weathering and alteration products, the element tends to correlate with elements such as Fe, Cr and V in weathered material subjected to partial digestion, and is thus an indicator of the presence of mafic rocks.
