Geochemical Symbol: Mg
Typical Detection Limit (Aqua Regia/ICP): 0.01%. NOTE: Many common minerals that host Mg, whether as a primary or trace constituent, are resistant to strong-acid digestion routinely used in commercial geochemical labs. Therefore, digestion is never 100%.
Typical Detection Limit (Neutron Activation): N/A


Variable; frequency distribution tends to be complete in limestone, dolomitic or ultramafic terrain

Exploration Geochemical Applications
1. As a Pathfinder

None known

2. As an Aid to Geological Mapping

High values indicate mafic or ultramafic rocks (in association with Cr, Ni, V etc.) or calcareous rocks (with Ba, Ca, Sr).
