This book was released on 2005 with total page 394 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to improve our understanding of poorly studied Mexican Porphyry Copper Deposits in the SW regional metallogenetic province, a detailed study of the hydrothermal fluid evolution of La Caridad porphyry copper-molybdenum deposit, and its connection to a high sulfidation epithermal deposit, was performed using oxygen, hydrogen and sulfur stable isotopes combined with fluid inclusion studies. In addition, U-Pb and Re-Os geochronology from La Caridad, Milpillas and El Arco porphyry deposits were performed to constrain the timing of mineralization and magmatism in northwest Mexico. Uranium-lead zircon ages from La Caridad suggest a short period of magmatism, between 55.5 and 53.0 Ma. Re-Os molybdenite ages from potassic and phyllic hydrothermal veins yielded identical ages within error, 53.6" 0.3 Ma and 53.8" 0.3 Ma, respectively. Four stages of hypogene alteration and mineralization are recognized at La Caridad porphyry copper deposit. The isotopic composition of the water in equilibrium with hydrothermal alteration minerals is consistent with highly evaporated lacustrine waters mixed with magmatic waters or vapor separated from magmatic fluids, however, sulfur isotopes and fluid inclusions data support the lacustrine-magmatic water hypotesis. Milpillas porphyry copper deposit in the Cananea Mining District, yielded a crystallization age of 63.9" 1.3 Ma. Two Re-Os molybdenite ages yielded an identical age of 63.1" 0.4 Ma, Suggesting a restricted period of mineralization. Re-Os data indicate that mineralization in Cananea District, spanned 4̃ m.y. in three discrete pulses at 5̃9 Ma, 6̃1 Ma and 6̃3Ma. El Arco porphyry copper deposit, Baja California, Mexico, yielded a Middle Jurassic crystallization age (U-Pb) of 164.7" 6.7 Ma and a Re-Os mineralization age of 164.1" 0.4 Ma and not 1̃00 Ma as previously determinated. Porphyry copper deposits in Mexico range in age from 164 Ma to 54 Ma and the mineralization in Sonora state ocurred in two different periods, but magmatism overlaps in space and time.
Download or read book Hypogene Alteration and Mineralization in the Dos Pobres Porphyry Cu Au Mo Deposit Safford District Arizona written by Daniel Russin and published by . This book was released on 2008 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dos Pobres is unusual among Arizona porphyry deposits in that it is relatively gold- and bornite-rich, and magnetite-bearing and is intimately associated with relatively mafic (quartz monzodiorite-low silica granodiorite) porphyry dikes. Conversely, it has considerably less pyrite and acid alteration than most other Arizona porphyry deposits. These features are like those in many other Au-rich porphyry systems, and they have also stimulated comparisons with andesite-hosted iron-oxide (-Cu-Au) (IOCG) systems such as Candelaria.

Download or read book Distribution and Styles of Hypogene Alteration and Mineralization in the Miami inspiration Porphyry Cu Mo Deposit Globe Miami District Arizona written by Nathan T. Swaim and published by . This book was released on 2020 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Miami-Inspiration porphyry Cu-Mo deposit is associated with a Late Cretaceous/Early Paleocene pluton in the southwestern North American porphyry Cu province. Hypogene Cu and Mo mineralization in the Miami-Inspiration deposit is related to porphyritic intrusions of the Schultze Granite (67-61 Ma) and is manifested as vein- and veinlet-hosted and disseminated sulfides in the Schultze Granite and the ~1.7 Ga Pinal Schist. The deposit has been rotated and extended by several generations of mid-Tertiary normal faults which have tilted originally shallower forms of alteration toward the northeast while deeper forms are exposed in the southwest portions of the deposit. Map patterns show that pervasive sulfide-poor potassic alteration (K-feldspar-quartz-biotite ± pyrite) in the southwest and center of the deposit is in contact with sulfide-bearing potassic (K-feldspar-quartz-biotite-chalcopyrite-pyrite) and transitional potassic-sericitic alteration (stable K-feldspar-sericite-chalcopyrite-pyrite) to the north and northeast. Early dark micaceous veins are present in strongly localized pockets in barren potassic alteration, and gray-green sericite veins are present in the sulfide-bearing potassic zone. Sericitic alteration (quartz-sericite-pyrite) postdates and overprints potassic and transitional potassic-sericitic alteration, as sericite pervasively replaces hydrothermal K-feldspar. Propylitic alteration (chlorite-magnetite-epidote-actinolite-calcite) is observed in the northeastern portions of the deposit, while coarse muscovite (“greisen”) alteration (muscovite-quartz-K-feldspar ± pyrite ± chalcopyrite) overprints potassic and barren potassic alteration and mineralization in the southwestern parts of the system. Copper mineralization (chalcopyrite and minor bornite) is mostly concentrated in the sulfide-bearing potassic, transitional potassic-sericitic, and sericitic alteration zones. Vein-hosted molybdenum mineralization in quartz + molybdenite veins and veinlets is common where potassic alteration is overprinted by sericitic alteration. These interpreted alteration and mineralization patterns are similar to other quartz monzodioritic-granitic porphyry Cu-Mo systems in the Globe-Miami district and the southwestern porphyry province.
