Numerous studies have explored the characterization of DZs by modeling fault formation processes. Most Brazilian Pre-salt reservoirs have early faults associated with depositional tectonic development overprinted by late faults that formed at greater depths. Both faulting events can markedly affect the present-day DZ widths. Previous studies have investigated the development of DZ during the early faulting stage. However, the late faulting stage and its impact on DZs have not been explored. Thus, our goal is to investigate the impact of both the early and late faulting stages in the structural evolution of DZs in carbonate rocks through geomechanical analyses. The results indicate that burial during the late faulting stage increases confinement and enhances the integrity of the rock far from the DZ, while the DZs triggered during the early fault formation remains unchanged. In addition, for the late faulting stage, we assess the role of fault roughness on the DZ by adopting friction coefficients to represent smooth or rough surfaces. The results show that rough fault surfaces contribute to lower fault displacements.</div></div>","PeriodicalId":50035,"journal":{"name":"Journal of Structural Geology","volume":"199 ","pages":"Article 105498"},"PeriodicalIF":2.6,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144633298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the garnet microstructure in calc-silicate rocks from Cheongsong, South Korea, was analyzed to elucidate its petrofabric evolution during contact metamorphism and concurrent plastic deformation. Three garnet types were categorized based on their microstructures using scanning electron microscopy, electron backscattered diffraction, and electron microprobe analysis. Type I garnet is characterized by garnet clusters formed by multiple nucleation and coalescence at the preferred nucleation site. Type II garnet shows intense deformation due to dislocation creep. Type III garnet exhibits chemically zoned structures with light-colored garnet surrounding dark fragmented garnet, interpreted as fractured relict garnet partly dissolved and replaced by Fe-richer garnet. Transmission electron microscopy images of types II and III garnet showed evidence of dislocation creep. Deformation temperatures were estimated using the quartz c-axis fabric opening angle thermometer, ranging from 708 to 741 ± 50 °C. Considering the water-rich environment and metamorphic mineral assemblage, the actual deformation temperature of calc-silicate rock is suggested to be approximately 650–700 °C, consistent with garnet plastic deformation conditions.

In this work we analyzed, from the point of view of anisotropy of magnetic susceptibility (at low-temperature and room temperature), Devonian (29 sites) and Ordovician-Silurian (3 sites) sedimentary rocks in the Pyrenean Axial Zone, totalling 611 samples. The main target is to determine the strain in relation to the Variscan (polyphased) and Alpine orogenies in limestones and shales. The magnetic information also derives from thermomagnetic curves, acquisition of the isothermal remanent magnetization (IRM) and coercivity of the remanence analyses, together with hysteresis loops and stepwise thermal demagnetization of induced IRM in 3 axes techniques. The analyses of magnetic properties were complemented with optical microscopy observations and calcimetries. In two of the sample areas (Sen and Llisat valleys), the minimum axes of the magnetic susceptibility ellipsoid (k_min axes) are mostly perpendicular to bedding whereas in the other two (Zinqueta valley and near Posets peak area), a more developed tectonic fabric is found: the k_min axes are not completely perpendicular to bedding, and the magnetic susceptibility ellipsoid relates to the foliation plane. Different minerals carry a concordant magnetic fabric with pyrrhotite, magnetite (ferromagnetic <em>s.l.)</em> and phyllosilicates (paramagnetic), and little influence of calcite grains (diamagnetic). The magnetic fabric is interpreted to form at the early stages of the Variscan deformation, prior to the dextral transpression synchronous with granite emplacement that characterizes the late stages of the Variscan Orogeny.

Gilbert from the late 19th century have attracted geologists' attention into the 21st century. Gilbert's memoir on the Henry Mountains includes two mechanical models based on physical theory found in W. J. M. Rankine's Manual of Applied Mechanics. Rankine's analysis of the stratification of hydrostatic fluids of different densities corresponds closely to Gilbert's Model #1 applied to magmatic intrusions. However, the sedimentary rocks of the Henry Mountains are not fluids, and though Model #1 failed Gilbert's tests, he did not reject it. Model #2 replaced the flexure over the laccolith with an encircling fault, enabling Gilbert to analyze laccolith formation using balanced parallel forces. His tests of Model #2 were successful and led to a physical relationship between the diameter and depth of laccoliths. We modernize Gilbert's methodology using the equations of motion for the material continuum provided by A. -L. Cauchy's First and Second Laws. These apply to rocks that deform and fracture as brittle solids, and those that deform plastically as ductile solids, as well as to magmas that flow as viscous fluids. This egalitarian functionality means that: 1) most geological structures are candidates for models based on Cauchy's Laws; 2) geologists must specify the constitutive properties of the deforming rocks or magmas; and 3) these models satisfy the conservation laws of mass and momentum.

To investigate the influence of preexisting damage on brittle fragmentation under these conditions, we study the behavior of heat-treated sandstone under dynamic tensile loading. Heat-treatments induce microfractures and mineralogical changes, simulating preexisting damage that can exist due to processes related to tectonic deformation, exhumation, and faulting-induced damage. A modified sample configuration for a Split Hopkinson Pressure Bar (SHPB) apparatus is used to induce tensile fragmentation in Berea Sandstone samples heat-treated at 250 °C, 450 °C, 650 °C, and 850 °C, and we analyze deformation in post-mortem samples using optical and scanning electron microscopy. Permanent strain during experiments is accommodated by the formation of mode-I fractures, dilation bands, and pore space expansion that can result in localized porosity increases of up to 25 %. Tensile strength increases with heat-treatments up to 450 °C and then decreases for heat-treatments at temperatures above the α-β-quartz transition. Elastic properties of Berea Sandstone also change with heat-treatments, and in a single orientation the Poisson's Ratio becomes negative at heat-treatments above 250 °C. Whereas fractures induced by SHPB experiments are primarily intergranular for sandstone heat-treated at temperatures up to 450 °C, intragranular fractures become more prevalent in sandstone heat-treated at 650 °C and 850 °C. Intragranular cracks emanating from grain contacts are observed in samples loaded under tension, but the mechanism of their formation is different than morphologically similar “Hertzian” fractures formed under compression. We propose a model for contact emanated tensile fractures formed under a remote tensile stress field that resemble Hertzian fractures formed under compressive loading. Finally, we compare our experimentally damaged sample to naturally deformed sandstones from the damage zone of the San Andreas Fault and Serpent Mound Impact Structure in Ohio, and we show distinct features that are likely indicative of brittle damage formed under macroscopic tensile loading. Our results have implications for dynamic tensile brittle fragmentation of sandstone with preexisting damage during earthquake rupture, landslides, and impact cratering.
