  1. Porphyry Copper Systems* RICHARD H. SILLITOE† 27 West Hill Park, Highgate Village, London N6 6ND, England Abstract Porphyry Cu systems host some of the most widely distributed mineralization types at convergent plate boundaries, including porphyry deposits centered on intrusions; skarn, carbonate-replacement, and sediment-

  2. Porphyry Cu systems host some of the most widely distributed mineralization types at convergent plate boundaries, including porphyry deposits centered on intrusions; skarn, carbonate-replacement, and sedimenthosted Au deposits in increasingly peripheral locations; and superjacent high-and intermediate-sulfidation epithermal deposits.

  3. Porphyry copper deposits provide around 75% of the world’s copper and are an important source of gold and other metals (Sillitoe 2010). One aspect of porphyry deposit models that is poorly understood …

  4. Gold-Rich Porphyry Deposits: Descriptive and Genetic Models and Their Role in Exploration and Discovery RICHARD H. SILLITOE 27 West Hill Park, Highgate Village, London N6 6ND, England Abstract Gold-rich porphyry deposits worldwide conform well to a generalized descriptive model. This model

  7. It is well known that magmatic-hydrothermal breccias (Sillitoe, 1985) in porphyry copper deposits can give rise to substantially higher-grade hypogene (and supergene) mineralization because of the greater permeability and resultant fluid focusing that they provide (Fig. 3).
