Tectonic framework of surface and blind structures from neotectonic and geophysical (gravimetry) analyses, Central Andes of Argentina

This work describes new evidence of N–S and oblique trending surface and blind structures in the La Cantera-Gualilán tectonic depression in the Central Precordillera, San Juan Province, Argentina. Two main N–S Quaternary thrusts cross longitudinally the valley located ∼60 km west of San Juan city (30° 50′- 31° 17′ S and 68° 55′- 69° 05′ W). One of them is located in the eastern piedmont of the Sierra de La Invernada (San Juan Fault) and the other in the western piedmont of the Sierra de La Cantera (La Cantera Fault System), although the northward continuation of this structure has not yet been confirmed. Besides, a smooth water divide or “portezuelo” controlled by an oblique transpressive structure (Divisadero Coba Rubia Fault) separates two N–S elongated river basins with opposite water flow directions. One of these is the Gualilán River, which flows from south to north, and the other corresponds to the La Cantera River, running from north to south. In the present work, we describe some new natural exposures and subtle geomorphological evidence of Quaternary structures identified in the Gualilán-La Cantera tectonic depression. We also use regional and local gravity data to analyze and interpret gravity anomalies related to these surface or blind active structures. Then, based on our geologic and geophysical interpretations, we infer the presence of several, buried cross-strike structures with NW and NE trends, one of them coincident with the drainage divide between the Gualilán and La Cantera opposite river basins, possibly related to the Coba Rubia Fault. Also, we suggest the northward continuation of the La Cantera Fault System (LCFS) as a buried structure in coincidence with the Gualilán River alluvial plain. In this sense, the gravity response of the basement and these river sub-basins shows a close relationship with the surface and subsurface structures. We propose that the oblique structures could represent pre-existing crustal fabrics reactivated during the Andean orogeny, segmenting the N–S Precordillera fold and thrust belt system. Finally, according to the analyzed neotectonic and gravimetric features, we consider the La Cantera-Gualilán Valley as a potentially seismogenic source in this intraplate portion of the Andean Precordillera, crossed by several N–S and oblique surficial and buried/blind active structures. These tectonic features could play a significant role in a regional seismic hazard assessment.Fil: Alcacer Sanchez, Juan Manuel. Consejo Nacional de Investigaciones Científicas y Técnicas.

Quaternary faults with opposite vergency between Central and Western Precordillera, San Juan province

Se describen en este trabajo numerosas deformaciones cuaternarias presentes en el relleno sedimentario de la depresión longitudinal Matagusanos-Maradona-Acequión, ubicada entre la Precordillera Central y Oriental, en la provincia de San Juan, en el centro-oeste argentino. Esta depresión está surcada por estructuras frágiles submeridianas, afectando a depósitos aluviales pleistocenos y holocenos, y están organizadas según dos sistemas con vergencias opuestas: uno con vergencia oriental y estilo de piel fina, a semejanza de la Precordillera Central, y otro convergencia occidental y piel gruesa, como el de Precordillera Oriental, hecho que manifestaría la presencia de una zona triangular de piel gruesa. Este arreglo estructural se manifiesta prácticamente a lo largo de toda la depresión analizada, variando sin embargo, la posición del eje de dicha zona triangular hacia el este o el oeste.We herein present numerous evidence of Quaternary deformation within the fill of the Matagusanos-Maradona-Acequión depression, located between the Precordillera Central and Oriental, in the San Juan province of central-western Argentina. The Pleistocene-Holocene alluvial fill of this depression is crosscut by north-south trending thrust faults, arranged in two major trends of opposite vergency: a thin-skinned east verging one, very similar to the Precordillera Central style of deformation, and a second basement-involved west-verging one, resembling the structural style of the Precordillera Oriental, fact indicating the presence of a thick-skinned triangle zone. This structural configuration is present along most of this tectonic depression, although varying the position of the axis of this triangular area to the east and west.Fil: Perucca, Laura Patricia A..

Gravity collapse structures in the Central Precordillera fold-and-thrust belt, Argentina

Numerosas formas de relieve ubicadas en el área de la faja plegada y corrida de la Precordillera Central de Argentina, que a menudo se asocian con una tectónica compresiva, están de hecho relacionadas con procesos gravitacionales superficiales. Estas estructuras de colapso gravitacional se han desarrollado en el flanco occidental de las sierras de La Dehesa y Talacasto, éstas incluyen deslizamientos, caídas de rocas, pliegues en rodilla, deslizamientos planares y flaps, entre otros; que en conjunto constituyen un pliegue monoclinal que inclina entre 30º y 60º hacia el oeste. Las estructuras de colapso por gravedad son paralelas al rumbo regional de la Sierra de la Dehesa y se originan en calizas y dolomías del Ordovícico. Su pendiente hacia el oeste, la presencia de planos de estratificación, las fracturas y diaclasas; y la litología (intercalaciones de calizas con bancos incompetentes arcillosos) habrían favorecido su ocurrencia. El despegue y transporte inicial de las estructuras gravitacionales y deslizamientos de rocas en el flanco occidental de la Sierra de la Dehesa estuvieron estrechamente controlados por tres elementos estructurales: 1) la estratificación cuando inclina >30° en la dirección de la pendiente; 2) los juegos de diaclasas que constituyen grietas de tracción lateral y transversal que liberan tensiones por tracción; y 3) las discontinuidades que fragmentan superficies deslizantes. Algunos otros factores que podrían caracterizarse como locales (litología, estructura y topografía) y regionales (elevada actividad sísmica y posiblemente condiciones más húmedas durante el período post-glacial) fueron determinantes para favorecer la pérdida de equilibrio de la ladera occidental en las estribaciones orientales de la Precordillera Central.Several landforms found in the fold-and-thrust belt area of the Andean Central Precordillera of Argentina, which were often associated with tectonic shortening, are in fact related to superficial gravity tectonic structures. These gravitational collapse structures have developed in the western flank of sierras de La Dehesa and Talacasto. These include rock-slides, rock falls, wrinkle folds, slip sheets and flaps, among others; which together constitute a monoclinal fold dipping between 30° and 60° to the west. Gravity collapse structures are parallel to the regional strike of the sierras de la Dehesa and Talacasto are placed in Ordovician limestones and dolomites. Their sloping towards the west, the presence of bed planes, fractures and joints; and the lithology (limestone interbedded with incompetent argillaceous layers) would have favored their occurrence. Detachment and initial transport of gravity collapse structures and rockslides in the western flank of the Sierra de la Dehesa were tightly controlled by three structural elements: 1) the bedding, when It is dipping >30° in the slope direction; 2) joint sets that constitute lateral and transverse traction cracks which release extensional stresses; and 3) discontinuities fragmenting sliding surfaces. Some other factors that could be characterized as local (lithology, structure and topography) and as regional (high seismic activity and possibly wetter conditions during the postglacial period) were determinant in favoring the steady loss of the western mountain side in the easternmost foothills of the Central Precordillera.Fil: Perucca, Laura Patricia A..

Gender Differences in the Factors Associated with Alcohol Binge Drinking: A Population-Based Analysis in a Latin American Country

Alcohol consumption is a public health problem in Peru, fostered by traditional practices, where promoting social interaction in celebrations, facilitating field work as a source of energy and warmth, and achieving objectives in certain labor negotiations, play an important role. However, research on the risk factors of binge drinking according to gender is limited. The study aim was to determine the factors associated with binge drinking in the Peruvian adult population by gender. An analytical study of secondary data from the 2018 Peruvian Demographic and Family Health Survey was conducted. The dependent variable was binge drinking in the last 30 days. Adjusted prevalence ratios (aPR) were estimated for the association between sociodemographic and health-related variables with binge drinking. A total of 32,020 adults were included. Binge drinking was found in 22.4%. Men (32.6%; 95% confidence interval [CI]: 31.4–33.8) presented a higher consumption pattern compared to women (12.8%; 95% CI: 12.0–13.6). For both genders, differences were found in binge drinking according to sociodemographic characteristics (age and wealth quintile was associated in both genders while the educational level was associated only for men, and ethnic self-identification and marital status for women) and health- characteristics related (health insurance, smoking in the last 30 days, overweight and obesity were associated in both genders). Several factors are associated with binge drinking according to gender in the Peruvian population, including age and education level among men, as well as marital status and ethnic self-identification among women

Neotectonic, morphotectonic and paleoseismologic analysis of the Las Chacras Fault System, Sierras Pampeanas Occidentales, San Juan, Argentina

Las Chacras Fault System is a Quaternary structure located in the western piedmont of Sierra de la Huerta in the Sierras Pampeanas Occidentales, in west-central Argentina. This fault system is subsidiary of the Valle Fértil Megafault System, the NW-striking master structure that affects the western flank of the Valle Fértil - La Huerta ranges. The Las Chacras Fault System comprise several sections including the Pan de Azúcar fault, which presents the most conspicuous evidence of tectonic Quaternary activity. The Pan de Azúcar fault affects three Quaternary alluvial surfaces (Q 1 , Q 2 and Q 3 ) along 26 km in the western piedmont of Sierra de La Huerta, where three natural exposures allowed us to observe Triassic rocks thrust over Quaternary deposits. The observation of different kinematic markers and the relative position of the units affected by the fault, allow us to define this fault as a reverse fault. This structure trends 325° and dips 25° NE. With a DGPS we carried out detailed topographic profiles perpendicular to the average strike of the fault, along interfluves and rivers that cross the structure, for the purpose of establishing the relationship between the topography and the slope of the terrain. This analysis indicates that Quaternary activity of the fault has played an essential role in controlling the piedmont geomorphology, generating west-facing scarps and drainage anomalies such as rivers with convex Hack profiles. Paleoseismic analyses indicate that the fault has moved after 18.360 ± 2990 yr BP. Furthermore, we calculated a net displacement for the Pan de Azúcar fault of ∼50 ± 0.2 m since the Late Pleistocene to Holocene, yielding a shortening rate and a slip rate of ∼0.16 ± 0.1 mm/yr. Thus, the Pan de Azúcar fault is a potential seismogenic source, which could produce a moderate earthquake between Mw = 6.4 and 7.0, with a recurrence interval between 2600 and 6900 years.Fil: Rothis, Luis Martin.

Holocene compression in the Acequión valley (Andes Precordillera, San Juan province, Argentina): Geomorphic, tectonic, and paleoseismic evidence

The Matagusanos-Maradona-Acequión Valley sits within the Andes Precordillera fold-thrust belt of western Argentina. It is an elongated topographic depression bounded by the roughly N-S trending Precordillera Central and Oriental in the San Juan Province. Moreover, it is not a piggy-back basin as we could have expected between two ranges belonging to a fold-thrust belt, but a very active tectonic corridor coinciding with a thick-skinned triangular zone, squeezed between two different tectonic domains. The two domains converge, where the Precordillera Oriental has been incorporated to the Sierras Pampeanas province, becoming the western leading edge of the west-verging broken foreland Sierras Pampeanas domain. This latter province has been in turn incorporated into the active deformation framework of the Andes back-arc at these latitudes as a result of enhanced coupling between the converging plates due to the subduction of the Juan Fernández ridge that flattens the Nazca slab under the South American continent.This study focuses on the neotectonics of the southern tip of this N-S elongated depression, known as Acequión (from the homonym river that crosses the area), between the Del Agua and Los Pozos rivers. This depression dies out against the transversely oriented Precordillera Sur, which exhibits a similar tectonic style as Precordillera Occidental and Central (east-verging fold-thrust belt). This contribution brings supporting evidence of the ongoing deformation during the Late Pleistocene and Holocene of the triangular zone bounded between the two leading and converging edges of Precordillera Central and Oriental thrust fronts, recorded in a multi-episodic lake sequence of the Acequión and Nikes rivers. The herein gathered evidence comprise Late Pleistocene-Holocene landforms of active thrusting, fault kinematics (micro-tectonic) data and outcrop-scale (meso-tectonic) faulting and folding of recent lake and alluvial sequences. In addition, seismically-induced effects already reported in the literature by this working team further support the tectonic activity of neighboring faults in the Holocene. As a concluding remark we could state that the ongoing deformation in the region under study is driven by a compressional regime whose maximum horizontal stress in the late Pleistocene-Holocene is roughly east-west oriented. This is further supported by focal mechanism solutions.Fil: Audemard, Franck Albert. Venezuelan Foundation For Seismological Research; Venezuela.

Analysis of La Dehesa paleo-landslide: Central Pre-Andes of Argentina

The main objective of this paper is to consider the influence of Quaternary faults as likely triggering factor for rockslides occurrence in the Central Pre-Andes, a region with intense shallow seismic activity. A rockslide deposit was selected as study case, placed in the western flank of La Dehesa and Talacasto (DT) range (31°3′37″ S and 68°46′ 8″ W). Applied methodology includes the characterization of main discontinuities, reconstruction of the topography using a high-resolution digital elevation model, safety factor calculation along the sliding surface and, Newmark displacements estimation for three different hypothetical seismic scenarios, recreated from existing neotectonic local information. Equilibrium-limit method's results confirm that study case, La Dehesa rockslide (LDR), had a stable and safe slope's configuration under static conditions. However, a seismic horizontal coefficient between 0.2 and 0.3 decreases safety factor below the safety threshold. Newmark's displacements for different seismic reconstructed scenarios varies between 4.1 and 15.9 cm, values that agreed with a coherent failure process, likely triggered by Pleistocene to Holocene seismogenic sources in Central Pre-Andes. LDR trigger could be assigned mainly to an earthquake related to La Dehesa Quaternary fault (LDF) activity; however, similar movements produced by neighboring faults should not be discarded. LDR triggering related to climatic conditions is despised. Finally, the methodology presented in this work is easy to reproduce and may be applied to other rockslides located in the mountainous areas of the Central Pre-Andes of Argentina.Fil: Tapia Baldis, Carla Cintia.
