Conventional Rb–Sr and total fusion ⁴⁰Ar/³⁹Ar techniques are insufficient to spatially-resolve distinct microstructures, such as inherited and recrystallized micas associated with fault zones developed under low to medium-temperature conditions. Here we present <em>in situ</em> Rb–Sr geochronology of fine-grained micas from fault-related rocks of the São Francisco Craton margin, in the Southern Espinhaço Range (SE Brazil), to investigate the timing and effects of fault reactivation at the dawn of Gondwana assembly. Fine-grained muscovite and biotite from slickensides yield Rb–Sr isochron ages spanning 500–450 Ma associated to thrust faults reactivation. This tectonic reactivation is coeval with brittle-ductile deformation of marbles in the footwall of the main regional thrust zones. These novel mica Rb–Sr ages indicate that thrust reactivation was 30–80 Ma younger than the last regional metamorphic event related to collisional deformation in the Araçuaí Orogen, coinciding with the timing of post-collisional magmatism and a fluid flow event in the cratonic margin. We envisage that fault reactivation in the São Francisco Craton margin might be associated with thermal post–orogenic relaxation due to gravitational collapse of the Araçuaí Orogen, with gravity-driven mass transport from the orogenic core causing compressive reactivation in the external fold-thrust-belt. These new results indicate that the Brasiliano thrust fronts remained active throughout the main interval of biogeochemical development in the Ediacaran–Cambrian transition post-Gondwana assembly.</div></div>","PeriodicalId":50035,"journal":{"name":"Journal of Structural Geology","volume":"191 ","pages":"Article 105305"},"PeriodicalIF":2.6,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142742942","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}

They are zoned syeno-monzogranitic, strongly peraluminous intrusive bodies representing typical Carboniferous intracontinental magmatism in the Eastern Sierras Pampeanas of Argentina. Both plutons present ellipsoidal external shapes, and sharp and discordant contacts with the host rocks suggesting an emplacement with high rheological contrast between the intrusive magma and the metamorphic host rock. The geophysical study highlights an elongated, arcuate gravimetric low that coincides and is aligned with the long axis of both plutons and with a zone characterized by brittle structures. Regarding structural measurements, the main penetrative structure of the host rocks (Ancasti Formation) shows an averaged NNW-SSE orientation and presents a slight but significant variation close to the plutons. Magmatic fabrics were observed in the porphyritic units (K-feldspar megacrysts) that constitute part of the igneous bodies.

Fieldwork and subsequent morphometric and structural analyses confirmed notable tectonic activity in the area. Geomorphic indices were applied to assess tectonic activity, yielding an average index of relative tectonic activity (Iat) for all drainage basins, highlighting varying tectonic intensity levels across the Şiro Valley. Mountain front sinuosity (Smf) analysis indicated different uplift rates and tectonic forces along distinct fault segments. Additionally, Hypsometric Integral-Hypsometric Curve (HI-HC) index analysis pointed to rapid uplift processes, particularly in the eastern part of the fault-controlled basin, signaling active tectonic uplift and geomorphic rejuvenation. Normalized steepness index (ksn) and Chi (χ) values highlighted variations in erosion rate, providing insight into regional uplift patterns and knickpoint distributions. These findings align with the dominant transtensional tectonic regime in the area, as inferred from slip data inversions along the Şiro Valley. The region's fault geometry, oblique movement, and block rotations firmly support this interpretation. Comparisons of slip rates and ground deformation models revealed notable variations in fault behavior, suggesting ongoing energy accumulation, possibly linked to aseismic creep.
