Geochemical Symbol: Au
Typical Detection Limit (Aqua Regia/MIBK/ICP): 2-5 ppb
Typical Detection Limit (Neutron Activation): 2-5 ppb


Frequency distribution of analytical values usually truncated (censored); calculation of valid statistics possible in ~50% of data sets

Exploration Geochemical Applications
1. As a Pathfinder

Important pathfinder for gold; usefulness limited by inhomogeneity of dispersion ("nugget effect") in most natural media. Supporting anomalies of pathfinders such as As, Sb etc. are highly desirable

2. As an Aid to Geological Mapping

None known
