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 The simulation conditions were based on exploratory data from existing wells and unpublished results of Organic Geochemistry and x-Ray Diffraction from the 1-COST-1P-PR well, near Barra Bonita gas field.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 sedimentary section of the Early Silurian to Early Carboniferous in the Parnaíba Basin encompasses two lithostratigraphic units: the Serra Grande Group and Canindé Group, which are interpreted and reported in the current literature as supersequences limited by erosive events of regional character related to the Caledonian and Hercinian orogenies. This stratigraphic interval was analyzed based in geophysical data (gamma ray logs) and geological data (lithologic interpretation from the composite well logs) of wells drilled by the oil industry. Additionally, some 2D seismic data was used as support to partial interpretation. The variations in the pattern of the geophysical well logs (gamma ray) were interpreted as representative of lithofaciologic variations which was corroborated by the lithological description of the composite well log. The variations in the pattern of the geophysical well logs (gamma ray) was interpreted as representative of lithofaciologic variations which was corroborated by the lithological description of the composite well log. A sequence stratigraphic analysis based in the principles of T-R Sequence was applied to this data. This analysis allowed to propose a model to the stratigraphic evolution to the studied section, as constituted by 5 depositional sequences which showed a pattern of a progressive drowning of the basin until its maximum identified in the maximum flooding surface in the Devonian Sequence (E-SEQ-4). From this maximum the depositional pattern reverses to a transgressive trend. Within this stratigraphic context, the integration of the produced data and the information available from literature allowed the proposition of depositional models to the system tracts of the Silurian-Devonian (E-SEQ-3) and Devonian (E-SEQ-4) sequence. The proposed depositional models vary from continental depositional environment in the transgressive system tract 3, in the Silurian-Devonian Sequence, to a marine depositional environment in the regressive system tract 3, following to the Devonian Sequence (E-SEQ-4) with marine depositional environment in the transgressive system tract 4 and to the shallow marine environment in the regressive system tract 4

Abstract: The research presents new geological and structural data, in 25.000 scale, besides geochemistry and geochronology data of the Nova Prata target, located south of the Almas town, SE of Tocantins State. The region was prospect for gold, and several mines were described. In the geotectonic context is located in the NE segment of the Internal Domain of the Brasília belt, made up by Paleoproterozoic to Mesoproterozoic basement associations. In target area, seven lithological units were mapped in detail: two associations of orthogneisses, phyllonitic rocks, muscovite chlorite schists, greenschists, leucogranite and andesite-diorite bodies. The structural analysis resulted on the characterization of ductile phases including the Dn + Dn+1 main phases with the development of the main foliation and the stretching lineation, the Dn+2 late folding, besides and brittle structures as faults and fractures. Based on geometry, two structural domains separated by an oblique NE-SW fault, with reverse and dextral components, were characterized. Two generations of quartz veins were identified, the fist one parallel to the main foliation and related to the metamorphism, and the late one with irregular distribution. The southern domain is dominated by a penetrative N-S trending foliation, while the Northern domain is marked by a NE-SW foliation, discrete thrust shear zones and tight to open folds. Geochemical data suggest cordilleran arc-related to collision orogenic environments. New LA-ICPMS U-Pb data detected two magmatic pulses: the older one is represented by the southern orthogneisses with crystallization ages of ca. 2,46Ga, while the youngest one is defined by the ca. 2.2 Ga orthogneisses of the northern segment, that also display inherited zircons of the same age of the oldest group. Sm-Nd isotopic data for both the orthogneisses and diorite–andesite dykes point out the cordilleran setting, with reworking of older crustal rocks and some juvenile contribution, as suggested by weakly negative and positive εNd values

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
