Geochemical Symbol: W
Typical Detection Limit (Aqua Regia/ICP): 10-20 ppm NOTE: Most minerals that host W are resistant to strong-acid digestion routinely used in commercial geochemical labs. Therefore, digestion is never total.
Typical Detection Limit (Neutron Activation): 4 ppm


Typical frequency distribution truncation (censoring) well in excess of 50%

Exploration Geochemical Applications
1. As a Pathfinder
