We refer to this theory as Critical Energy Fault Failure (CEFF) and demonstrated its applicability to a range of rock failure experimental configurations from uniaxial to polyaxial loadings (Reches and Wetzler, 2022). In the present analysis, we utilized the energy-based CEFF theory to highlight further aspects of rock faulting: A. Evaluation of the dissipated energy associated with rock faulting which revealed that intact rock failure dissipates 35–55% of the available elastic energy. B. For a given normal stress, the CEFF calculated shear strength of a developing fault is smaller than the equivalent of the Coulomb shear strength. C. The predicted dilation associated with faulting of intact brittle rocks that is calculated by CEFF is supported by experimental observations.

However, the relationship between fault reactivation and mineralization remains ambiguous, particularly in the NE-SW-striking Taoshan-Zhuguangshan uranium metallogenic belt, South China Block. Field investigations, core observations, and paleostress inversions were carried out for the Lujing and Gulonggang hydrothermal ore fields. Field investigations and previous exploration profiles show that the main ore-controlling structures are the NE-SW-striking high-angle faults. The maximum density of poles shows that these faults dip mainly to SE at high angles (70–88°). Kinematic indicators and plunges of slickenlines indicate that these NE-SW-striking high-angle faults have undergone polyphase faulting and fault reactivation, including left-lateral strike-slip shearing, normal dip-slip motion, and right-lateral strike-slip shearing. Dip angles of faults (n = 667) and quartz veinlets (n = 407) in sub-vertical drill cores vary mainly from 30 to 65°and 60 to 70°for the Lujing ore field and from 20 to 50°and 25 to 85°for the Gulonggang ore field, respectively. The difference suggests that hydrothermal fluids migrated preferentially along the high-angle secondary fractures of the main faults. Paleostress inversions of fault-slip data (n = 375) revealed six stages of paleostress regimes, including 1) the early to middle Early Cretaceous extensional regime (subhorizontal NW-SE-trending σ₃), 2) the late Early Cretaceous strike-slip regime (subhorizontal NNW-SSE-trending σ₁), 3) the latest Early Cretaceous to early Late Cretaceous extensional regime (subhorizontal NW-SE-trending σ₃), 4) the latest Cretaceous strike-slip regime (subhorizontal WNW-SEE-trending σ₁), 5) the early Eocene strike-slip regime (subhorizontal NE-SW-trending σ₁), and 6) the middle to late Eocene extensional regime (subhorizontal NE-SW-trending σ₃). Field investigations, core observations, and previous metallogenic ages show that uranium mineralization in the Taoshan-Zhuguangshan uranium metallogenic belt occurred mainly along NE-SW-striking high-angle normal faults under the latest Early Cretaceous to early Late Cretaceous NW-SE extension. These high-angle normal faults were not new-born but reactivated from left-lateral strike-slip faults formed in the late Early Cretaceous strike-slip regime. NE-SW-striking polyphase faulting and fault reactivation during the Cretaceous were triggered by the subduction of the Paleo-Pacific Plate underneath the South China Block.</div></div>","PeriodicalId":50035,"journal":{"name":"Journal of Structural Geology","volume":"191 ","pages":"Article 105340"},"PeriodicalIF":2.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143151533","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}

Compared to strike-slip faults developed in an active tectonic settings, cratonic strike-slip faults have small-scale characteristics, weak activity and are difficult to identify without high-quality 3D seismic data. To date, there have been few in-depth investigations of this kind of strike-slip fault, leading to a poor understanding of its characteristics and genetic mechanisms. In this study, we extensively investigated the cratonic strike-slip faults discovered in recent years in the Ordos Basins of China via 3D seismic data, and conducted comparative analyses with similar features observed in other intracratonic basins and active tectonic settings. This study suggests that cratonic strike-slip faults have some special characteristics, such as small displacement and low maturity even when they have been active during several orogenic processes, vertical stratified structural style, and decoupling with the basin periphery structures in terms of trending direction and kinematics. This paper proposed an alternative formation mechanism for cratonic strike-slip faults. The cratonic strike-slip faults nucleate from fractures induced by regional compressive stress instead of being directly inherited from preexisting faults or basement faults. These fractures experience brittle shearing movement under various structural processes, such as plane-differential compression, oblique compression, block rotation, and finally evolve into long strike-slip faults. The development of cratonic strike-slip faults probably record the special stress transmission within the stable craton, the weak in-plane tectonic stresses in the intracratonic basin, which mainly operate at shallow depths. This formation mechanism can provide a new perspective for the understanding of brittle deformation on the earth's surface, and help to elucidate the occurrence of earthquake activity in stable blocks.</div></div>","PeriodicalId":50035,"journal":{"name":"Journal of Structural Geology","volume":"191 ","pages":"Article 105292"},"PeriodicalIF":2.6,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143150958","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}

Geological and geophysical data reveal significant along-strike differences in both shallow and deep structures within the belt, raising a critical question: What tectonic processes drive these structural variations? Considering that the Triassic collision involved pre-collisional accreted microcontinents and along-strike variations in convergence velocities, this study investigates the influence of microcontinental width, convergence rate, and initial Moho temperature on continental subduction styles using numerical modeling. The models incorporate pre-collisional accreted microcontinent(s) and reveal a two-stage subduction evolution: an initial transition from one-sided to two-sided continental subduction, followed by subduction polarity reversal. High initial Moho temperatures, rapid convergence rates, and wide accreted microcontinents promote the development of two-sided subduction, characterized by an initially vertical interface that gradually inclines towards the pro-plate as convergence progresses. These subduction styles significantly influence crustal suture migration. One-sided subduction results in minimal horizontal displacement, whereas two-sided subduction and polarity reversal lead to substantial horizontal shifts. Based on the modeling results, this study proposes a new evolutionary model for the Dabie-Sulu orogenic belt during the NCB-SCB collision. The model effectively explains along-strike structural differences, such as the inconsistent tectonic trends on either side of the Tan-Lu Fault and the opposite dipping directions of high-velocity mantle anomalies observed in geophysical profiles.
