Geological Setting
Where porphyry systems form
Conceptual Model
Porphyry system architecture
A simplified conceptual cross-section showing common alteration zones, intrusive architecture, and hydrothermal features.
Conceptual geology only. Alteration geometry, mineralization, intrusive relationships, and overprinting vary substantially between individual porphyry systems.
