Abstract. A broad spectrum of gold mineralization styles is found in the epizonal intrusive environment, and a number of these give rise to world-class gold deposits (Figure 6.1). Here the spectrum is subdivided into: (a) intrusion-hosted stockwork/disseminated deposits of both porphyry and non-porphyry types, the former possessing all the ...
