Geology

Alteration processes:Freeport Exploration Company (1985) identified phyllic, propylitic, and argillic alteration phases within the intrusive complex. The phyllic phase, thought to be the oldest, consists of moderate to strong sericitization, quartz overgrowths, and disseminated pyrite. Propylitic alteration cross-cuts and overprints the phyllic phase. Argillic alteration is restricted to faults and fractures and cross-cuts the other phases. Trujillo and others (1982) reported the argillic alteration to be widespread, intense, and pervasive.
