“…Four shade maps were produced using four illumination directions (0°, 45°, 90° and 315°) in the study area, which included the La Plata Granite and Páez Massif. Valleys and crests were extracted from each of the four shade maps (e.g., Bossennec et al, 2021; Celestino et al, 2020; Cianfarra & Salvini, 2015; Wise et al, 1985; Figure 3a).…”

Plutonic rocks typically have negligible matrix porosity and permeability. However, fractures and mineral alterations create storage space and flow pathways that turn plutonic rocks into fluid reservoirs. Despite significant hydrocarbon discoveries, naturally fractured reservoirs in plutonic rocks have been poorly studied. In most Colombian basins, the crystalline basement has undergone multiple deformational events and is thrust over the Cretaceous to Cenozoic source and reservoir rocks of the conventional petroleum system. This structural configuration is ideal for the migration of oil into a fractured basement. A multiscale fracture analysis, including field, petrographical and petrophysical techniques was conducted on the Permian and Jurassic plutonic basement of Upper Magdalena Basin in order to understand the controls on brittle deformation, the development of fracture networks and their potential to form hydrocarbon reservoirs. The results indicate that protolith textures and structures, including magmatic and mylonitic foliation, favours fracturing. Dykes exhibit higher fracture density (7–48 fractures/m), porosity (mean = 0.4%) and permeability (mean = 125,818.75 mD) than the host rock (2–25 fractures/m; 0.23%; 12,066.09 mD). Intersection zones from regional faults, are characterized by the highest fracture and lineament intensity. Our results suggest that dyke swarms and interacting damage zones can significantly enhance the reservoir quality of plutonic rocks by providing storage in fractures and fluid pathways to the host rock.

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.

“…Additionally, based on the kinematic and geometric interaction of the fault, the associated damage zones have been further divided into fault-approaching damage zones and fault-intersecting damage zones [5]. The mechanical characteristics of the rock and the regional strain distribution can be greatly influenced by fault damage zones [6,7], Therefore, identifying the width and distribution pattern of fault damage zones is essential for recognizing some very important aspects, i.e., the regional tectonic evolution [8,9], seismic characteristics [10,11], crustal fluid permeability [3,12], subsurface sequestration of CO 2 [13,14], and distribution of the ground stress field [15,16].…”

The distribution of damage zones around a fault has long been regarded as a frontier and hot spot in the field of geoscience but is still not fully understood. In this study, we conducted field investigations and tests around the Xianshuihe fault zone (XSHF), a left-lateral strike-slip fault with a length of about 400 km located in the eastern margin of the Tibetan Plateau. The results reveal that the fracture frequency and rock strength parameters present a spatially asymmetric distribution along the fault and have a negative power-law correlation with the distance from the fault. The widths of the damage zones are approximately 20.8 km and 17.1 km in the southwest and northeast directions, respectively. Combined with the previous studies, we presented a negative power-law function to depict the correlation between slip displacement and the width of the damage zone and found that the growth rate of damage zone in faults with low displacement is greater than that in those with large displacement. The study demonstrates that the asymmetric distribution of the damage zone surrounding the XSHF is mainly due to the stress redistribution in different damage zones stemming from the left echelon and different activity rates of the blocks on both sides of the XSHF.
