Six tuffaceous and sandstone levels from an Andean (Mio- Pliocene) synorogenic succession were analyzed using the U-Pb LAICP- MS method on detrital zircons, in order to constrain maximum depositional ages and to define the basin provenance and likely connections with the volcanic history of the South-Central Andes. The detrital ages of the differen...
A multiproxy analysis was conducted to determine the potential clay sources used in the production of archaeological pottery in the Characato region, Córdoba, Argentina. The results demonstrate that archaeological pottery production in Characato relied heavily on local clay sources rich in granitic aplastic inclusions and minimal material processin...

Clay mineral characterization is a valuable tool for unraveling the evolution of continental sedimentary basins. The Fiambalá basin is a foreland Andean basin located in the Southwest of the province of Catamarca (Argentina), on the flat subduction segment. In order to characterize its paleoenvironment and post-depositional evolution, petrographic,...
Reconstructing thermal histories in thrust belts is commonly used to infer the age and rates of thrusting and hence the driving mechanisms of orogenesis. In areas where ancient basins have been incorporated into the orogenic wedge, a quantitative reconstruction of the thermal history helps distinguish among potential mechanisms responsible for heat...
New X-ray diffraction (XRD) data, scanning electron microscopy (SEM) analysis, and X-ray energy dispersive spectrometry (EDX) microanalysis on clay minerals are presented for Cretaceous-Cenozoic sedimentary sections studied in the La Flecha and La Troya Sur creeks, located in the Argentine Precordillera. The characterization of clay mineral assembl...
In the Mesopotamia region (Argentina) basalts are exploited as aggregates for different applications. Depending on the alteration they have undergone, their properties can be affected, especially if the rocks are altered to swelling clay minerals. The objective of this work is to contribute to understanding the local alteration process of basalts f...
Detailed mineralogical analyses in areas with surface hydrothermal alteration zones associated with recent volcanism (<1 Ma) in the Central Andean Volcanic Zone could provide key information to unravel the presence of hidden geothermal systems. In the Cordón de Inacaliri Volcanic Complex, a geothermal field with an estimated potential of~1.08 MWe·k...
Existe desde hace ya más de una década, un consenso en la comunidad académica de que estamos atravesando una nueva época denominada Antropoceno (o Capitaloceno, como prefieren nominarlo algunos académicos críticos, ver en Maristella Svampa, 2019). Este concepto diagnóstico refiere a una época de profundas transformaciones antrópicas (sobre la denom...
La experiencia de ABEJAR y su formación didáctica en Pedagogías de la Tierra Este texto se inscribe en lo que se ha dado en llamar geopoéticas, la búsqueda de una narrativa distinta y propia en torno a las escrituras/relatos que hacemos sobre la Tierra. En este sentido, y coincidiendo con los ecotransfeminismos y sus propuestas de trabajo en ámbito...
Los minerales de arcilla son componentes fundamentales de los sedimentos y las rocas sedimentarias. Como es ampliamente conocido, las condiciones ambientales de las áreas de aporte y acumulación, donde el clima cumple un rol fundamental, conducen a la activación de procesos físico-químicos que conllevan a la generación de arcillas junto a otros min...
Sulphate, clay, silica and oxide-hydroxide minerals were identified by means of fieldwork, XRD and SEM, both in the active and fossil zones of the Cerro Apacheta volcano (Cerro Pabellón geothermal field, northern Chile). Mineral assemblages and their spatial distribution in the active zone allow defining Superficial advanced argillic alteration fac...
It is common practice to assume values for basal heat flow or basal temperatures as a lower boundary condition for thermo-kinematic models of crustal tectonics. Here, we infer spatial and temporal variations of the paleo-basal temperature from integrated modelling of thermochronological ages, to relate the inferred variations to the geodynamic sett...
New apatite fission track (AFT) and (U–Th)/He (AHe) data from two sections recording Cretaceous-Cenozoic clastic successions (La Flecha - La Troya Sur creeks) in the northern sector of the Central Precordillera of Argentina are presented. The results show that the Ciénaga del Río Huaco, Puesto la Flecha and Vallecito Fms. would have crossed the 60...
The Amarillo River in La Rioja, Argentina, is a natural acidic environment that is influenced by an abandoned mine. The river is characterized by extremely low pH and high concentrations of metals and metalloids. Fe(III)-bearing neoformed precipitated minerals are widespread along the hydrological basin. This work reports the presence of different...
Quartz-based hunter-gatherer lithic technology is present around the world. It occurs particularly where the Precambrian crystalline basement outcrops, including South Africa, Northern Europe, North America and large areas of South America. However, little effort has been made to try to characterize its chemical composition to help understand eithe...
Identifying the provenance signature and geodynamic setting on which sedimentary basins at convergent margins grow is challenging since they result from coupled erosional and tectonic processes, which shape the evolution of source areas and the stress regime. The Early Cretaceous evolution of the northern Andes of Colombia is characterized by exten...

This book describes the Paleozoic to Cenozoic evolution of the Chilean and Argentinean Andes. The book is structured from a historical perspective concentrating on specific processes explained in each chapter. The chapters cover dynamic subsidence; neotectonics; magmatism; long and short term deformation; spatial development of ancient orogenic pro...
Mantle convection can drive long-wavelength and low-amplitude topography, which can occur synchronously and superimposed to tectonics. The discrimination between these two topographic components, however, is difficult to assert. This is because there are still several uncertainties and debates in the geodynamic community, for example, the scales an...

The Famatina belt, Central Andes, is part of an ancient accretionary margin built along Western Gondwana in the early Palaeozoic. U–Pb ion microprobe analysis of detrital zircons and Sm–Nd whole-rock analysis of two early Palaeozoic low-grade metasedimentary units record the early evolution of this region. Detrital zircons in the Negro Peinado and...
La existencia de una unidad metamórfica de bajo grado, diferente a la Formación Negro Peinado, pudo establecerse a partir de estudios sedimentológicos, estratigráficos, mineralógicos, estructurales y geocronológicos de detalle realizados en el Famatina. Para esta nueva unidad se propone el nombre Formación Achavil (nom. nov.), se establece su local...
Many of the metamorphic and deformational events associated to low-grade units in NW Argentina have been linked with ancient orogenies, like the Pampean (Cambrian) and the Ocloyic (Ordovician) cycles. The lack of specific ages in the low-grade metamorphic rocks of the Famatina belt, as well as the absence of a detailed stratigraphic analysis, have...
Many of the metamorphic and deformational events associated to low-grade umts in NW Argentina have been linked with ancient orogenies, like the Pampean (Cambrian) and the Ocloyic (ordovician) cycles. The lack of specific ages in the low-grade metamorphic rocks of the Famatina belt, as well as the absence of a detailed stratigraphic analysis, have l...
A new low-grade metamorphic unit, different from the well-known Negro Peinado Formation, is suggested from sedimentological, stratigraphical, mineralogical, structural and geochronologic criteria developed after detailed field mapping in the region of Famatina. For this new unit the name Achavil Formation (nom. nov.) is proposed and its type locali...
Muchos de los episodios de metamorfismo y deformación asociados a las rocas de bajo grado del NO argentino fueron tradicionalmente vinculados con orógenos antiguos como el pampeano (CÁmbrico) y el oclóyico (Ordovícico). En el cinturón del Famatina, la falta de dataciones precisas y de un anÁlisis estratigrÁfico de detalle en las sucesiones con bajo...
Las formaciones Vinchina y Toro Negro (Mioceno Superior-Plioceno, Ramos, 1970), constituyen una de las sucesiones sinorogénicas andinas más espesas de Argentina y, posiblemente, de Sudamérica (Jordan y Alonso, 1987). Ambas forman parte de una megasecuencia continental, dominantemente fluvial, que localmente supera los 10 km de espesor (Ramos, 1970)...
Numerous, thin-bedded, tabular pale-yellowish clay bands are interlayered with black shales in a biostratigraphically constrained Early Ordovician volcano-sedimentary succession at Famatina, western Argentina. This region was part of a fairly continuous upper-plate, convergent volcanic chain that fringed western Gondwana. Mineralogy on both clay an...

En afloramientos expuestos sobre la vertiente oriental en la quebrada del río El Oro, es...
This contribution documents a folding episode orthogonal to the ocloyic deformation in the central region of Famatina, involving low-grade metamorphic units considered as part of the Negro Peinado Formation. At the Rio El Oro canyon, west of Chilecito, a first folding (P1) with ∼E-W fold axis, plunging westward (∼25°/20°), an axial plane of ∼75°/85...
La Formación La Aguadita aflora en la zona central del Sistema de Famatina (28º39' S), antepaís andino de Argentina, y es interpretada como producto de sedimentación sinorogénica en una cuenca de retroarco desarrollada en el margen occidental de Gondwana durante el Ordovícico. Esta unidad, considerada inicialmente por varios autores como parte de u...
The La Aguadita Formation crops out in the core of the Famatina Range (28°39'S) in the southern Central Andes and is interpreted as a relict of a synorogenic Ordovician clastic wedge developed in the retroarc of a collisional-subduction margin built along western Gondwana. This unit, formerly included within the Pampean (Early Cambrian) metamorphic...
