“…In agreement with previous works (Milani and Davison, 1988;Heine et al, 2013;Peralta Gomes et al, 2018), our data support the NW-SE extension direction during the rift phase of the Jatobá Basin, which also suggests reactivation of the brittleductile strike-slip faults present in the basement rocks (Fig. 17d).…”

The Borborema Province (NE Brazil) is characterized by the development of continental-scale transcurrent shear zones related to the Neoproterozoic Brasiliano-Pan-African Orogeny. These shear zones commonly border Cretaceous intraplate sedimentary basins . This work presents a structural and microstructural study of the Cruzeiro do Nordeste shear zone (CNSZ), which limits the northern border of the Jatobá Basin. The ductile deformation of the CNSZ is marked by high-angle, ENE-trending foliation bearing subhorizontal stretching lineation, with numerous kinematic indicators J o u r n a l P r e -p r o o f showing dextral shearing. We documented a continuous transition from hightemperature (high-T) to low-temperature (low-T) (c. 650 °C to c. 300 °C) ductile fabrics characterized, at the high-T end, by quartz recrystallization by grain boundary migration and feldspar recrystallization by subgrain rotation, and, at the low-T end, by bulging recrystallization of quartz and extensive fracturing of feldspars. The cooler semi-brittle to brittle deformation superimposed on the mylonites is characterized by conjugate pairs of strike-slip mesoscopic faults. The orientation of these faults (WNW-ESE, dextral, and N-S, sinistral) suggests they were formed under the same stress field than the ductile fabrics and thus evidence a continuum deformational from the ductile to the brittle field associated with exhumation during transcurrent tectonics. Brittle reactivation of the CNSZ is characterized by normal faults overprinting the mylonitic foliation. We report a U-Pb age from fault-hosted calcite slickenfibres of 135 ± 4.7 Ma, which provides constraints on the timing of brittle reactivation that can be associated with opening of the South Atlantic Ocean.

“…Thus, the tectonic study of the syn‐rift intracontinental basins is an excellent proxy for a better understanding of the Pangea Breakup event (Frizon De Lamotte et al., 2015). In the Borborema Province, northeastern Brazil, the initial stress responsible for the Pangea Breakup is recorded as dykes (Matos et al., 2021) and intracontinental syn‐rift sedimentary basins (Celestino et al., 2020; Gomes et al., 2018).…”

“…Based on structural data, seismic interpretations, and potential data, previous studies discussed the Cretaceous syn‐rift (Sénant & Popoff, 1991; Françolin et al., 1994; de Castro et al., 2007; Marques et al., 2014; Gomes et al., 2018; Celestino et al., 2020) and the Cenozoic post‐rift tectonic inversion (Marques et al., 2014; Nogueira et al., 2015; Vasconcelos et al., 2021) of the intracontinental basins of Northeast Brazil during the Pangea Breakup. Several works tried to constrain the evolution of intraplate tectonic activity responsible for the opening of intracontinental sedimentary basins in the Borborema Province using the RPB as the most representative case study (e.g., De Castro et al., 2007; Marques et al., 2014; Nogueira et al., 2015).…”

As the magnetic fabric is concordant with the gross petrofabric of the rock (Borradaile, 1988), it represents a powerful tool for tectonic reconstructions, even in rocks at a low grade of deformation or in zones where deformation is not visible (Cifelli et al., 2004;Schwehr & Tauxe, 2003).Pangea Breakup is one of the most important events in the tectonic history of the Earth. This event started at ∼145 Ma and determined the present-day continent configuration (Heine et al., 2013;Moulin et al., 2010;Peace et al., 2020). Its understanding is crucial as one of its main results is the opening of the Atlantic Ocean. The event was responsible for the rifting events that resulted in several sedimentary basins in South and North America, Africa and Europe, not only at the coast but also in intracontinental settings (

The significance of the tracer testing technique is widely accepted in reservoir performance analysis in hydrology as well as in hydrocarbon exploration and production. The subsurface reservoir delineation for hydrocarbon exploration and optimum production is one of the most critical aspects of petroleum system analysis. The quality of the reservoir and its performance prediction require extensive knowledge of qualitative reservoir geology, its depositional environment, facies heterogeneity and engineering properties of subsurface formations. Tracer testing is amongst the few techniques available in the oil and gas (O&G) industry, which stands up to these expectations and is successfully used for quantitative determination and analysis of sub-seismic scale structural and stratigraphic heterogeneities. Tracer testing is also being utilized in determining residual oil saturation (Sor) and lateral correlation of reservoir properties in the subsurface. Apart from the O&G industry, the concentration-based applications of tracer testing have been proved in hydrology, geothermal and medical science. A comprehensive review is presented to explain the application of tracer testing technique to investigate porous media, mainly in O&G industry. The type of tracers used, their selection criteria, concentration, and natural versus gradient and qualitative to a quantitative application are discussed in the current review. Generally, two types of tracers (chemical and radioactive) are preferred in the petroleum industry for gas/fluid flow assessment, waterflood optimization and establishing connectivity between multiple wells. The current paper reviews both types of tracer tests, namely single well and inter well, in detail discussing the objectives, calculations, designing, injection, sampling, laboratory analysis and knowledge integration. The preliminary aim was to provide a review of the tracer testing technique used in reservoir evaluation and well-to-well connectivity analysis.
