The branch of earth science focused on the chemical makeup of solid rocks and minerals. Exploration geologists use lithogeochemical sampling to detect subtle alteration halos and trace element anomalies that point toward hidden mineral deposits deep underground.
Heard on the job
The lithogeochemistry results show a distinct depletion in sodium, which is a good vector for massive sulfide mineralization.
