AbstractThis study underscores the critical role of carbon capture and storage (CCS) in mitigating greenhouse gas emissions and addresses the potential for CCS projects in saline aquifers in Brazil, one of the world's largest carbon emitters. The country's ability to adopt CCS is significantly influenced by the availability of data related to regional CO2 storage potential and identifying suitable geological framework for CO2 injection. While oil and gas reservoirs have traditionally been prioritized, saline aquifers represent an underexplored and potentially higher capacity storage option. Despite Brazil's 31 sedimentary basins, the data quantity and availability for these contexts remain insufficient for advanced studies on the geological storage of CO2 considering saline aquifers. An initial study was conducted indicating five potential targets in the Paraná and Potiguar Basins for geological storage in saline aquifers based on available public data, mainly drilling data. This review reveals substantial challenges related to the evaluation of Brazil's CO2 storage capacity, such as the lack of modern seismic studies, the absence of a regulatory framework for CO2 storage, and insufficient investment in new well exploration. These challenges necessitate multistakeholder collaboration, the development of a supportive regulatory environment, and investment in extensive site characterization campaigns. Addressing these barriers is fundamental to realizing the country's CCS potential and contributing to global decarbonization efforts. © 2024 Society of Chemical Industry and John Wiley & Sons, Ltd.

Application of Volume Uncertainty for Resource Classification: A Case Study on the Rondon Do Pará Bauxite Deposit, Brazil

This study illustrates the application of conditional simulations to calculate the uncertainty associated with the thickness of bauxite ores. The bauxite deposit of Rondon do Pará in northern Pará State, Brazil, is characterized by a well-defined lateritic profile, with the ore being composed of two sequential horizons: massive bauxite and ferruginous bauxite. This study used ore thickness data from 1.005 drillholes with different grid spacing. Drillhole intervals of both types of bauxite ore were accumulated, converting the database from 3D to 2D. Sequential Gaussian simulation produced probability maps calculated from certain confidence intervals, which permits obtaining the uncertainty associated with estimates in thickness. Results show that in portions with the same regular drillhole spacing there are different ranges of uncertainty and variability, which could be useful to support resource classification, associating different confidence intervals to resource classes. This analysis could also guide the drilling program for resource conversion in order to optimize costs, indicating areas where there is greater uncertainty and would need to be densified. The incorporation of this information into the resource model could be very helpful for supporting subsequent studies of economic evaluation and risk analyses with respect to this type of deposit or similarly in mineral exploration.

Structural control and timing of evaporite-related Mississippi Valley-type Zn–Pb deposits in Pucará Group, northern central Peru

Abstract The South America MVT belt comprises the deposits of San Vicente, Shalipayco, Florida Canyon, and some minor Zn–Pb occurrences hosting in the carbonates and evaporites of the Pucara Group, in an extension of more than a thousand kilometers from the center to the north of Peru. Structural constraints of the MVT Peruvian deposits are conditioned by deep sub-vertical secondary extension structures with general N, NNE or NNW direction related to strike-slip movements superimposed on previous Andean NW thrust structures. Recent studies on Shalipayco and Florida Canyon deposits point to similar processes of rock formation, diagenesis and mineralization acting in province scale. New isotopic data of Pb–Pb and Rb–Sr in sulfides summed with a compilation of the available data for the evaporite-related MVT deposits and studies on the structural and tectonic evolution of the Peruvian Andes allowed establishing correlations of local process of the deposits to the regional Andean tectonic events. The Florida Canyon saline dome structure was attributed to Jurua Orogeny (157–152 Ma). The stage of dolomitization forming the porous dolostone and evaporite breccia during burial diagenesis is attributed to the period between Jurua and Mochica stages. The oil migration to these reservoir rocks occurred probably during Mochica event (100–95 Ma). The Rb–Sr dating of sphalerite from the Florida Canyon deposit together with temporal field relations indicated that the Zn–Pb sulfide ore formed in or just after Peruvian Orogeny (86-83 Ma).

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
Society of Economic Geologists
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.
