Abstract

Porphyry copper stockwork morphology and formation environments are discussed. It is shown that stockwork and orebody forms depend on morphology of ore-bearing porphyry intrusion apical parts and host environment petrophysical features. Presence of low-permeability strata in ore-magmatic system tops affects porphyry intrusion and associated orebearing stockwork form. Ore-hosting rock brittle or ductile deformability, along with fluid saturation, initial metal content and sizes of ore-bearing intrusive bodies, determines the scales of ore-generating hydrothermal system manifestation within porphyry copper deposits.
