  • Mineral characterisation of the non-sulphide Zn mineralisation of the Florida Canyon deposit, Bongará District, Northern Peru

    ABSTRACTThe Florida Canyon deposit hosted by a carbonate-evaporite sequence of the Pucara Group, Peru, has both Zn–Pb sulphide and Zn non-sulphide mineralisations. The mineralogical characterisation of samples from the deposit enables the definition of a supergene assemblage dominated by smithsonite, in addition to hemimorphite, cerussite, and goethite. The main oxidation in the study area involved the direct replacement of primary MVT stratabound sulphide ore. In comparison with other non-sulphide deposits of the Bongara District, the Florida Canyon deposit can be correlated with the Cristal deposit by means of the original sulphides preserved in the supergene textures, the similar hosting dolostone layer, lack of hydrozincite, and depth of emplacement, which are characteristics that contrast with those of the Mina Grande deposit, also inserted in the Pucara Group. The Florida Canyon supergene mineral assemblage is a paleoclimatic indicator suggesting a humid tropical climate during the late Miocene in t...

  • The Zn-Pb mineralization of Florida canyon, an evaporite-related Mississippi valley-type deposit in the Bongará district, northern Peru

    Abstract The Florida Canyon evaporite-related Zn-Pb sulfide deposit, in northern Peru, is one of the largest Mississippi Valley-type deposits in South America. Triassic carbonate and former evaporite-bearing rocks of the Pucará Group host the orebodies that constitute two different styles: (1) predominantly stratabound ore associated with hydrocarbon-rich porous dolostones and evaporite dissolution breccias and (2) high-grade ore associated with evaporite breccias representing diapiric injections along faults. A dome structure that controls the location of the ore deposit was defined by drill hole spatial data; the dome likely resulted from halokinetic processes during Andean deformation. NNE-trending, steeply dipping secondary faults linked to major northwest structures appear to control the distribution of ore grades in the deposit. Mineralization postdated hydrocarbon migration and accumulation. Strontium, carbon, and oxygen data isotope signatures allow distinction between pre- and synmineralization carbonate stages. The sulfur isotope composition of sulfides in the deposit suggests they precipitated as the result of mixing of a metal-rich fluid with resident hydrogen sulfide in the dome. Local thermochemical sulfate reduction may have contributed to the reduced sulfur budget during mineralization.

  • The lateritic bauxite deposit of Rondon do Pará: A new giant deposit in the Amazon Region, Northern Brazil
    Saulo Batista De Oliveira, Marcondes Lima Da Costa and Hélcio José Dos Prazeres Filho

    Economic Geology, ISSN: 03610128, eISSN: 15540774, Volume: 111, Pages: 1277-1290, Published: August 2016 Society of Economic Geologists, Inc7811 Shaffer ParkwayLittletonCO 80127
    Detailed geologic surveys (including mapping, drillings, trenches, and mineralogical and chemical analyses) have delimited a new giant lateritic bauxite deposit with 642 million metric tons (Mt) of 42.7% Al2O3 (available) in the world-renowned Amazon Province, northern Brazil. The mineral resource is part of a mature laterite profile and consists of reddish to mottled clay at the base that narrows upward to massive bauxite, followed by ferruginous bauxite, and is capped by an iron horizon (nodular and columnar ferruginous crust) and nodular bauxite with a clayey matrix; a thick clay cover sealed the profile after abrupt contact. The bauxite ore is composed of gibbsite in addition to goethite, hematite, and kaolinite. In general, the ore has high concentrations of Al2O3 (avg 52.4% in massive bauxite and 39.9% in ferruginous bauxite) and Fe2O3 (avg 14.8% in massive bauxite and 35.1% in ferruginous bauxite) and low concentrations of SiO2 (avg 4.33% in massive bauxite and 3.21% in ferruginous bauxite) and is therefore of metallurgical grade. Geologic contact features together with REE distribution patterns indicate that the horizon successions were formed in situ via alteration of the basal sedimentary rocks through polyphasic bauxitization events. These features are comparable with those of other world-class bauxite deposits in this province, such as Trombetas, Juruti, and Paragominas. The Rondon do Para bauxite orebody consists of massive bauxite and ferruginous bauxite layers. The last layer is a differentiated horizon that is not always present in other deposit profiles; when it is present, however, it is not classified as ore. Correlation with other Amazonian bauxite deposits demonstrates that the Rondon do Para deposit is of lateritic origin, was formed during the Paleocene-Eocene, and was reworked in the Miocene.
