What is Pervasive Alteration in Porphyry Systems about?
The document discusses hydrothermal systems associated with porphyry copper deposits at various depths. It notes that these systems were active over large areas and depths, from shallow to deep levels, resulting in varying chemical and mechanical environments that influenced deposit evolution. Fracturing of cooling plutons and changes in lithostatic pressure and stress over time affected fracture patterns and styles. While exposures are limited, data suggests similarities in alteration styles and sequences
