Porphyry copper deposits are copper orebodies that are formed from hydrothermal fluids that originate from a voluminous magma chamber several kilometers below the deposit itself. Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages

    The Christmas copper deposit, loed in southern Gila County, Arizona, is part of the major porphyry copper province of southwestern North America. Although Christmas is known for skarn deposits in Paleozoic carbonate rocks, oregrade porphyrytype copper mineralization also occurs in a composite granodioritic intrusive complex and adjacent mafic volcanic country rocks.

    Hydrothermal: Ore minerals are precipitated by a hydrothermal solution percolating, through intergranular spaces and along bedding planes and fractures in the host rocks

    These data constrain interpretations of the nature and extent of fracture permeability at different stages of cooling of the quartz monzonite porphyry which invaded the Ruby Star Granodiorite.Fracturing coeval with formation of the orebody extends into the granodiorite some 4.5 km from the center of the hydrothermal system.

    porphyry alteration and mineralization is characterized by veins and fracture filling, and replacement textures between two episodes of alteration and sulfide minerals. Alunite and kaolinite replaced sericite, accompanied with covellite, digenite, enargite, and

    NATURE AND EVOLUTION OF FRACTURE RELATED PERMEABILITY The dominating element of flow porosity or permeabil ity in porphyryplutoncentered systems is the fracture network. Because fracture networks are shown to evolve sequentially, however, the total number of cracks measur able in rocks is not a measurement of characteristics useful in a

    1 Preliminary Model of Porphyry Copper Deposits Byron R. Berger, Robert A. Ayuso, Jeff Wynn, and Robert R. Seal Porphyry copper deposits result from the complex interactions and feedbacks of many

    The Red Hills intrusive complex is the easternmost porphyry MoCu system of Laramide age in southwestern North America. This study constrains the timing between igneous phases, and compares their geochemical characteristics with dikes from the Shafter silver deposit in order to support a possible link to a similar magmatic source.

    The bright red shading in the video above represents the area where the grade shell reaches the surface. The Santo Tomás project, loed in northern Sinaloa State Mexico, hosts a porphyry copper deposit, comprised of fracture and disseminated Cu and Mo sulphides, with significant Au and Ag credits.
