La spectrométrie peut-être utilisée pour cartographier l’empreinte de l’altération d’un dépôt porphyrique à cuivre.
 

The Casino deposit is a Cu-Mo porphyry deposit located in Yukon.

Gamma ray spectrometry detected potassium enrichment due to potassic alteration associated with the porphyry copper deposit.

Low eTh/K ratios indicate potassium enrichment relative to normal lithological signatures, indicating that the potassium anomaly is due to alteration.

A stacked profile clearly shows the relationship of the radioelements and the magnetic response over the deposit.
