The Early Cretaceous marine deposits of the Agrio Formation are widely distributed in southern Mendoza and Neuquén provinces, Argentina. The stratigraphic distribution of upper Valanginian to upper Hauterivian organic-w...

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 fossils of the India Muerta Formation (Neogene, Tucumán Province, Northwestern Argentina) include several vertebrate groups, mainly metatherian, xenarthran, and notoungulate mammals. Nevertheless, these remains have...

The Península Valdés region is situated in an intraplate position of the South American Plate, in the Patagonian foreland close to the Argentine Continental shelf. This region has a complex geotectonic evolution that s...

In the Alicia Quarry (S 37º 2´ 75”´´ and W 60º 20´ 25´´), located in the southern area of the Sierras Bayas, Olavarria region, Tandilia System, Buenos Aires Province, Argentina, a 150 m thick sedimentary succes...

We present new biostratigraphic data provided by ammonites, calcareous nannofossils, and calpionellids from Las Alcantarillas, a 127 m-thick section from the Neuquén Basin, western Argentina. The combined biostratigraph...

In this paper we illustrate the stratigraphy, geochronology, and geochemistry (major, minor, trace elements and Sr-isotopes) of a Holocene tephra layer found within coastal sedimentary deposits north of Caleta Olivia (Sa...

El presente estudio trata sobre la bioestratigrafía de conodontes del tramo medio-superior de la Formación San Juan (Ordovícico Inferior-Medio), en la sección expuesta en la quebrada Los Gatos, ubicada en la vertient...

The excavation construction of twin parallel tunnels is simulated by using centrifugal model tests. The internal stress and deformation variation of shield structure of the existing tunnel and the ground surface settleme...

Se describe un área de alteración aflorante en la región de Cerros Amarillos, ubicada en el curso superior del río Atuel, en la Cordillera Principal del sur de Mendoza (35°S, 70°O). La zona de alteración está esp...

The family Cardiliidae has been scarcely studied. It was historically placed in the superfamily Mactroidea. Members of this family are characterized by a cordiform shell with a typical mactrid hinge, posterior adductor m...

This study reports LA-ICP-MS U–Pb ages and Lu–Hf isotope data of detrital zircons from sedimentary rocks of the Nanduan Formation in the Changning–Menglian tectonic belt. The U–Pb age spectra display three domina...

Sauropodomorph dinosaurs dominated the herbivorous niches during the first 40 million years of dinosaur history (Late Triassic–Early Jurassic), yet palaeobiological factors that influenced their evolutionary success ar...

The study of the pre-Mesozoic geological history of NE Mexico offers the opportunity to reconstruct the processes that occurred at the NW margin of Gondwana. The Huizachal–Peregrina Anticlinorium, which is located west...

Se realizó el relevamiento de las sedimentitas de la Formación Montaña (Triásico) en el área de Santa Clara, en el norte de la provincia de Mendoza, Argentina. Durante el levantamiento de datos se determinó la exis...

En este artículo se abordan las estrategias tecnológicas implementadas por los grupos humanos que habitaron el curso inferior del arroyo Corrientes a partir del análisis tecnomorfológico de materiales líticos recupe...

Despite recent advances in wetland studies, ancient wetland deposits are still not well documented, and their facies characteristics are poorly registered. Sedimentary facies and sequence stratigraphic analysis of the Mi...

Las exploraciones de Roth, las colecciones resultantes muchas ahora ubicadas en La Plata, Zúrich, Ginebra y Copenhague, y sus importantes aportes en temas geológicos -especialmente estratigráficos- y paleontológicos,...

The Tunas Formation crops out in the eastern sector of the Ventania System (southwestern Buenos Aires Province, Argentina) and represents the last unit of the Pillahuincó Group (Pennsylvanian–Cisuralian). This work in...

The Roca San Miguel (RSM) archaeological site was occupied during Mousterian times. Here we present a geoarchaeological and paleoenvironmental reconstruction of the site. Five stratigraphic units (A to E) formed by diffe...

This study presents an integrated geophysical approach for shallow subsurface characterization using seismic refraction and Ground Penetrating Radar (GPR) at the Florida Atlantic University Boca Preserve. A 240 m transec...

Abstract This study presents an integrated static reservoir characterization of the Upper Cretaceous Bahariya Formation in the Berenice Field, North Western Desert, Egypt. A multidisciplinary workflow combining geologica...

Neogene sedimentary deposits cover approximately 10,000 km2 in the southern sector of San Luis province, in the central-western region of Argentina. These sediments mainly consist of sandy loessoid continental deposits a...

In this article we present the new open-air Middle Pleistocene locality Marathousa 2, which was discovered during a double intensive and targeted field survey in the lignite mines of the Megalopolis basin (Greece). The l...
