Nuestro trabajo se centra el estudio geoquímico del volcanismo desarrollado durante el Eoceno-Mioceno inferior sobre la precordillera andina, entre las localidades de S.C. Bariloche y Corcovado (41º-43º30´S).Las secu...

Este trabajo se realizó a partir de la hipótesis de trabajo: "los centros volcánicos emplazados alrededor y por encima del domo resurgente de la caldera Vilama (Puna argentina-Altiplano boliviano) con posterioridad a ...

El presente trabajo se realizó en un sector de aproximadamente 300 has, ubicado en la porción central del Macizo del Deseado. Las rocas que afloran en la zona están comprendidas predominantemente rocas piroclásticas...

Para el sur de Mendoza, se ha propuesto la existencia de un período prolongado de baja ocupación humana provocado por un aumento de la aridez durante el Holoceno medio. También se ha planteado que el poblamiento siste...

The Pliocene- Quaternary times in Extra-Andean Patagonia are characterized by the effusion of intraplate basalts. This work is focused on those basalts outcropping between 40° and 46°S. The age of this volcanism varies...

The northernmost part of the oil-producing Austral Basin, known as Aisén Basin or Río Mayo Embayment (in central Patagonian Cordillera; 43-46°S), is a special area within the basin where the interplay between volcanis...

The Pire Mahuida Volcanic Complex (PMVC), located in the extra-Andean region of12 southern Argentina (68º to 68º 40´W and 41º 51´ to 42º 28´ S), is a bimodal volcanic field13 that developed during the Miocene (17M...

Abstract Petit‐spot volcanism occurs in intraplate settings along the outer rise of subducting plates. Here we present evidence for petit‐spot type of volcanism from multibeam bathymetry and backscatter data from the...

We investigate the use of Hg as a proxy for volcanism by studying four distal and two proximal sections in relation to the Deccan volcanic center, straddling the Cretaceous-Paleogene (KPg) boundary at (a) Højerup (Denma...

The late Cenozoic retroarc volcanism in the Southern Central Andes (34°S-38°S) exhibits pronounced geochemical variations, which provide critical insights into subduction-related mantle processes and magmatic systems. ...

La Alta Sierra de Somún Curá es uno de los complejos volcánicos terciarios post-plateau en el ambiente de la meseta basáltica de Somún Curá, en la Patagonia extrandina. En ella se encuentra el cerro Corona, un volc...

One of the largest silicic igneous provinces of the world, the Chon Aike Volcanic Province, is related to an extensional regime developed in Patagonia in Early to Middle Jurassic times. This work presents new geochemical...

Episodes of Environmental Change (EECs) were times of accelerated hydrological cycle that punctuated the Early Cretaceous. Uncertainties in the geologic time scales however preclude full understanding of the onset, unfol...

Los domos riolíticos representan fases efusivas dentro de la evolución de estructuras volcánicas poligenéticas o erupciones que construyen edificios volcánicos monogenéticos espacialmente aislados o formando parte ...

Evidence of teratogenesis and mutagenesis documented in the palynological assemblages of the Middle Triassic Quebrada de los Fósiles Formation, San Rafael Depocenter (Mendoza, Argentina) provide an independent testimony...

Abstract Oceanic Anoxic Event 2 (OAE2, ∼94 Ma) represents a major global cycle perturbation in the mid‐Cretaceous greenhouse that is commonly attributed to increased biological primary productivity stimulated by ele...

Abstract The Early Permian witnessed the first icehouse‐to‐greenhouse turnover of the vegetated Earth, yet its climate dynamics remain enigmatic. Here, we used mercury (Hg) isotopes from pelagic and continental succe...
