Small-shield volcanoes are not the most abundant within this monogenetic field; however, they are important because they emplace large volumes of lava flows. Little work has been done on these volcanoes, so many unanswered questions exist about their origin, distribution, morphology, volume, and tectonic control. Based on geological mapping, stratigraphy aided by new ⁴⁰Ar/³⁹Ar radiometric dates, petrographic, chemical, and structural analyses, we characterized five small-shield volcanoes south of the Penjamillo graben to establish the eruptive chronology of the study area and evaluate their tectonic control. Stratigraphy and radiometric ages obtained from the literature and the five new ⁴⁰Ar/³⁹Ar ages reveal that more than a dozen small-shield volcanoes were emplaced in the region throughout the Pleistocene between 2.09 and 0.11 Ma. The rocks associated with these volcanoes have andesitic calc-alkaline composition, with a mineral assemblage composed of plagioclase, pyroxene, olivine, and Fe-Ti oxides. The region is characterized by being structurally complex, suggesting that tectonic structures favor the ascent and emplacement of mafic magmas to form small-shield volcanoes.

Maintaining a detailed and comprehensive seismic compilation is essential for assessing seismic risks in intracontinental regions, where earthquakes typically have longer recurrence periods than those in tectonically active zones. This compilation includes precise information about the date, time, epicenter location, hypocenter depth, and magnitude of seismic events. Uruguayan seismicity is characterized by low to moderate-magnitude events, consistent with its geological location away from major tectonic plate boundaries. The study analyzes data from the national seismological network, including broadband and short-period seismometers strategically distributed throughout the country. Focal mechanisms primarily indicate reverse faults with some strike-slip displacement, with fault planes having approximately N-S strikes, consistent with the regional stress regime. Notable seismic events are discussed, including the Florida earthquakes of 2021 and 2022 and the Atlántida earthquake of 2023. The research employs several long-known methodologies and novel ones, such as applying AI techniques to detect events. Public perception and response to seismic events are also analyzed, highlighting the importance of education on seismology and seismic risk. This study underscores the need for continuous seismic risk assessment, especially in southern and central Uruguay, and emphasizes the role of ancient geological structures in accommodating current tectonic stresses. The findings contribute to refining seismic hazard models for Uruguay and provide a foundation for future paleoseismic studies to understand long-term seismic patterns in this intracontinental region.</div></div>","PeriodicalId":50047,"journal":{"name":"Journal of South American Earth Sciences","volume":"161 ","pages":"Article 105578"},"PeriodicalIF":1.7,"publicationDate":"2025-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143947235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The La-Sc-Th ternary diagram was employed to trace sediment provenance. Our results revealed contrasting impacts of land-use changes. Mirim Lagoon showed barium enrichment which was previously attributed to coal mining and combustion, while Mangueira Lagoon exhibited increased REE concentrations post-1950, likely linked to the use of agricultural fertiliser. Nicola Lake, by contrast, demonstrated minimal anthropogenic influence. Sediment dilution and resuspension in larger systems, such as Mirim Lagoon, mitigated observable changes despite intense land-use activities.

This study investigates the impact of the coexistence of deformation bands and hydrothermal silicification on the fluid flow based on a outcrop composed of conglomeratic sandstone within the damage zone of the Portalegre Fault in the Rio do Peixe Basin, an analog of siliciclastic reservoir in the northeastern of Brazil. Previous studies divided this outcrop into three zones according to the presence and degree of silicification: Zone I (non-silicified), Zone II (moderately silicified), and Zone III (intensively silicified). Porosity and permeability models were constructed for each zone, and numerical fluid flow simulations were conducted. Our results showed significant alteration of the permoporous properties, leading to significant fluid flow anisotropy. Zone I exhibited the highest oil recovery, with an average recovery factor of 34 %. Flow analysis revealed that silicification controlled the flow direction, and deformation bands were overridden by silicification. The silicification process led to a significant increase in anisotropy, which was crucial for enhancing sweep efficiency. This alteration elevated the tortuosity of fluid flow, thereby improving the lateral sweep efficiency within the study area. This process reduced hydrodynamic properties, causing strong permeability anisotropy, primarily attributed to mineral dissolution and the formation of preferential flow paths.

Phases of aeolian transgressive sand sheets (TSS) are recorded in an extensive stretch of the Holocene barrier of the southernmost coast of Brazil from the millennial to modern ages. Ancient phases of TSS are evident in the modern transgressive dunefield (TDf) of the Concheiros Barrier, marked by vegetated, crenulate low precipitation ridges. In this work, we examined surface and subsurface records of aeolian deposits, exploring possible past climate conditions that led to the formation of these features. A 1000 m-long Ground Penetrating Radar (GPR) cross-section was conducted to determine whether these aeolian morphologies are observed in the stratigraphic subsurface record. Optical Stimulated Luminescence (OSL) dates were taken from vegetated relict TSS phases on the coastal barrier. The GPR section identified a single radarfacies, interpreted as a TSS. A few TSS units could be individually recognized, indicating overlapping low precipitation ridges/TSS margins. OSL dating indicated aeolian activity at 30 ± 3 years (P01), 1244 ± 123 years (P02), and 1464 years ± 130 years (P03). The youngest age is correlated with sand mobilization from AD 1996–2000, as described by previous studies. This phase was induced by climate conditions and it was caused by decreased vegetation cover, lower rainfall and water tables, and increased wind velocity and aeolian drift potential. The episodes of TSS mobilization at 1244 (±123) and 1464 (±130) years ago may have been caused by either drier conditions or intensified wind regimes, as noticed in different parts of southern Brazil by other studies.

The increase in seismic energy during the first days of October 2016, also led to a precautionary evacuation of a nearby community. Elevated levels of SO₂ flux were observed during the peak effusive phase in the early days of October, resulting in acid rain towards the southwest of the volcano. An analysis of the Frequency Index (FI) of discrete seismic events showed a change from low frequency energy to a high frequency energy; for several volcanoes this has proved to be a valuable indicator for assessing the transitions between ductile behaviour to a brittle state. For volcanic monitoring, it is crucial to comprehend parameters related to the transition from effusive to explosive activity. Additionally, the occurrence of seismic event families indicates a repetitive non-destructive source with events sharing similarities in waveform and spectral characteristics. Locating rockfalls through the amplitude attenuation method proves effective in identifying areas where lava flows, rockfalls, or Pyroclastic Density Currents (PDCs) occur. Photogrammetry was utilized to calculate the volume and effusion rate during the initial effusive stage, yielding a value of 1.3 m³s^-1, consistent with typical rates for lava dome growth.
