Abstract: In order to identify possible unconventional natural gas reservoirs in the Ponta Grossa Formation and to assess, probabilistically, undiscovered recoverable resources, stratigraphic and geochemical analyzes were performed using twelve exploratory wells located in the south-central portion of the Paraná Basin, which has a privileged location between the brazilian southeast and south regions, where the largest gas and electricity consuming centers are located. The simulation conditions were based on exploratory data from existing wells and unpublished results of Organic Geochemistry and x-Ray Diffraction from the 1-COST-1P-PR well, near Barra Bonita gas field. The best estimate (P50) is 2,9 billion cubic meters standard. If five existing wells are deepened at least to the top of Furnas Formation, the additional unconventional resource (P50) is 1,9 billion cubic meters. It is not recommended to extrapolate the volumes calculated for other basin’s areas without knowing the new data and without making the respective adjustments. The statements and conclusions are subject to an expressive set of risks, uncertainties and assumptions and, therefore, do not reflect the totality of the circumstances and the scenarios that may affect the investment decisions and their results. The Devonian source rocks’ geochemical features were compared between zones with distinct thermal maturities. Although the Frasnian source rock has TOC up to 4% in the immature zone, twice the TOC of the Emsian source rock, its depositional conditions were more oxidizing, therefore, less suitable to organic matter preservation. Furthermore, the occurrence area of Frasnian source rock is smaller, limited to southern Mato Grosso, where it is immature, and to northern/northwestern Paraná, where it is severely affected by igneous’ heat. In case the geological, technological, economic, environmental and legal factors are favorable to the resumption of exploratory activities, the results may contribute to the planning of future research on unconventional natural gas reservoirs

Abstract: The granitoids of Cambuci Domain, situated between Rio de Janeiro and Espírito Santo states, were divided into four main groups: (1) Serra Bolivia Complex (CSB) - Heterogeneous Orthogranulites and Orthogneisses; Grey Fine grained Orthogneiss; and charnockites of Monte Verde Region (2) leucogranites / leucocharnockites gness of the São João do Paraíso Suite (SSJP) (3) Grey Foliated Granite (4) Isotropic Leucogranite. The CSB is characterized by type I calc character of magmatism, generate in volcanic arc environment (Monte Verde Suite) and crustal reworking (Leucocratic ortogranulites). The Fine grained Greenish, is considered in this research as the embasement rock for the Oriental Terrain, crystallized during the Paleoproterozoic - Riacian (2184.3 ± 21 Ma) and recrystallized during in the metamorphic event in the Neoproterozoic - Edicarian (607.2 ± 1.5 Ma), whose TDM age is 2936 Ma. The Medium grained Leucocratic Ortogranulite was crystallized in the Neoproterozoic - Edicarian (between 592 and 609 Ma) and its TDM age is ca. 2100 Ma, which features heritage record in the Paleoproterozoic. The Monte Verde Suite is characterized by a magmatism calcialcalin and the Córrego Fortaleza Suite, magmatism calc-alkaline high K, both show magmatic arc signature. Records two magmatic pulses in a sample (JP-RM-08A) in the Neoproterozoic - Edicaran: the first one in 592 ± 2 Ma, and TDM age 1797 Ma, and the second one in 571.2 ± 1.8 Ma (injecting a charnockitoids). For all CSB rocks, protomylonítics, Mylonitic and locally ultramilonítics features were portrayed. Geochemical data show these SSJP granitoids are the calc-alkaline series of high-K, crystallyzed in Neoproterozoic (ranging from
610.3 ± 4.7 Ma to 592.2 ± 1.3 Ma). TDM ages show outliers in two samples: 1918 Ma and 2415 Ma, suggesting that have been generated from different sources. The Gray Foliated Granite belongs to the shoshonitic series, type I and metaluminous and are intraplate granites. However, could have been formed into arc cordilheirano, with crustal contamination of other sources. This fact would be confirmed by the TDM ages calculated ≈ 1429 - 1446 Ma. The Isotropic Leucogranite occurs in the form of dykes, NW direction, has massive texture and is inequigranular. Geochemical data show these granitoids are metaluminous the type I shoshonitic series. They are intraplate granites. The Isotropic Leucogranite represents the post-collisional magmatism which took place between 80 and 90 Ma years after the collisional event in central sector of Ribeira Belt. It is crystallized in the Cambrian (512.3 ± 3.3 Ma e 508.6 ± 2.2 Ma) and TDM ages, ca. 1900 Ma

Abstract: This current study aims to characterise the mineralogical content of the Irati formation and interpret any observed variations in terms of the paleoenvironmental and paleoclimatic conditions, and stratigraphic context of the formation. For correlation purpose we also discuss the organic content of the Irati Formation and its economic importance. Stratigraphic information and samples of the Irati formation were obtained from two wells (SP-32-PR and SP-58-PR), within the Sapopema Municipal of north-eastern Paraná state. Despite the proximity of the two wells the geological context of the Irati formation varies greatly from one well to the other. In well no. SP-58-PR the Assistência Member of the Irati Formation is intruded by a 60 m thick diabase sill whilst this sill was not encountered in well no. SP-32-PR. Mineralogical investigations involved X-ray diffraction (XRD), Scanning Electron Microscopy (SEM)and Energy Dispersive X-ray Spectroscopy (EDS). The distribution of organic material, variations in porosity, total carbon content (TOC), sulphur content (S), insoluble residue (IR) content as well as other Rock-Eval pyrolysis data of the Irati formation is presented in this study. The analytical results for the Irati Formation sampled in well no. SP-32-PR indicate the presence of authigenic minerals particularly within the upper portion of the Assistência Member. It also contains the highest values of TOC, S content and IR content. The correlation allows us to suggest that the paleoambiental conditions of this interval was characterised by the circulation of alkaline fluids within a restricted marine environment dominated by pelagic sedimentation which allowed the accumulation of organic rich sediments. The occurrence of gypsum and the absence of kaolinite suggest possible arid condition for the studied interval within the pelitic Assistência Member. Variations in mineralogical content within the Irati Formation can be used to help identify surfaces of sequence stratigraphy such as the limit between the Taquaral and Assistência Members, or the limit with the overlying Serra Alta Formation. The organic geochemistry of the Assistência Member confirms its potential as a source rock, although this interval is considered to be thermally immature. XRD of the Assistência Member sampled within well no. SP-58-PR indicates the presence of high-temperature minerals such as talc and pyroxene related to the intrusion of the diabase sill. SEM/EDS identified enstatite and plagioclase in the samples taken from close to the intrusive contact. These minerals appear to have formed through the reaction of quartz and saponite (smectite). In contrast, hydrothermal alteration in more distant intervals led to reactions between dolomite and quartz to generate talc and calcite.

Abstract: The evolution of the Ribeira belt resulted from the progressive amalgamation of several terranes against the eastern margin of the São Francisco Craton between ca. 620 and 580 Ma. The Oriental Terrane includes a diachronic evolution of two magmatic arc domains against the craton at ca. 580 Ma: Italva and Costeiro domains. This work brings new field, U-Pb geochronology, lithogeochemistry and isotopic (Sm-Nd and Sr) data from Serra da Prata and Rio Negro magmatic arcs and their tectonics relationships. Rocks from the Serra da Prata arc (860 - 830 Ma) are composed of medium-K calc-alkaline diorites and tonalites, with geochemical LILE and ETR signatures compatible with intra-oceanic magmatic arc scenarios. Isotope data, 87Sr/86Sr(i) = 0.7050 to 0.7079, εNd(i) = +3.4 to +5.1 and TDM =1.09 - 0.92 Ga near the age of arc crystallization, reveal their juvenile contribution. The Italva Group is composed of siliciclastic metasediments (Euclidândia Unit), whose the provenance pattern suggests that the Serra da Prata arc was the main source (800 - 850 Ma). Besides that, marbles (São Joaquim unit) with amphibolite (MORB e IAT) intercalations with crystallization age of 835 Ma define the minimal age of platform carbonates deposition into Italva basin. Unpublished and published data show that Rio Negro arc is composed of medium to high-K calc-alkaline rocks from gabbro to granodiorites and geochemical signatures of LILE and ETR compatible with continental magmatic arcs. U-Pb geochronology and isotopic data, 87Sr/86Sr(i) < 0.705 to 0.721, Nd(i)= -14 a +5 and TDM = 2.47 - 0.99 Ga, reflect their progressive evolution from a primitive intra-oceanic arc (from ca. de 790 Ma) to continental arc (to ca. de 605 Ma). The developement of Costeiro basin includes metasediments from Macuco unit (biotite gneisses with associated marbles) and São Fidélis Group (high-grade metasedimentary successions), both intruded by Rio Negro arc rocks. U-Pb provenance studies show Neoproterozoic sources from Serra da Prata and Rio Negro arcs for the Macuco unit. During the most intense interval of activity of the Rio Negro arc, between 630 and 620 Ma, intrusive, metamorphic and migmatitic events were recorded all over the Italva domain, interpreted as possible pre-arc basement for the construction of the Costeiro domain. The data from both magmatic arc episodes contrast with the evolution of the younger Serra da Bolívia (620 - 590 Ma) and Rio Doce continental arcs (630 - 590 Ma). Nevertheless, these data are similar to other juvenile magmatic arcs such as Santa Quitéria (ca. 880 to 830 Ma) in the Borborema Province, Goiás magmatic arcs in the Brasilia belt (ca. 900 to 786 Ma) and São Gabriel-Passinho arc in the Dom Feliciano belt (ca. 900 to 700 Ma), located respectively along the northern and western margin of the São Francisco craton and eastern margin of the Rio de La Plata craton. In a Western Gondwana scenario, the combination of the evolution of Tonian juvenile intra-oceanic arcs and Cryogenian-Ediacaran continental arcs, suggests more than 200 m.y. of subduction, continuous or not, around the older cratonic blocks that made up Western Gondwana which requires a protracted consumption of oceanic lithosphere
