Pearce element ratio PER analysis was proposed in 1968 as a graphical method to be applied in petrology. Using major element chemical compositions of rocks it allows for the determination of primary mineral parageneses. The application of the technique was later expanded to include studies of hydro thermal alteration associated with mineral deposits. This study tests the applicability of
