Marine sedimentary rocks of the lower Miocene Monte León Formation of southeastern Patagonia (Austral Basin), Argentina are important geological archives for better understanding regional tectonics, paleoenvironments, o...

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...

The Ediacaran Period (635-542 Ma) witnessed a series of extraordinary events. It arises with the end of the Marinoan Glaciation and deposition of worldwide enigmatic cap carbonate deposits. This abrupt shift in paleoclim...

"Integrating field and laboratory data is possible if there are strong geologic criteria to relate them. This challenge demands understanding rocks from the fabric and mineralogy up to the architectural elements of rock ...

The geological province of Precordillera is located in western Argentina. It extends 450 km meridionally and 110 km from east to west (Fig. 1) (Furque and Cuerda, 1979). The Lower Paleozoic stratigraphy is characterized ...

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...

For the first time, the eastern flank at Cordón Santa Elena, within the Valle Hermoso district, has been mapped and described in detail. Based on key field observations, petrographic, geochemical and geochronological re...

El sitio arqueológico Cabeza de León 1 es una referencia en el Parque Nacional Monte León debido a la abundancia y variedad de materiales que lo caracterizan. La información disponible hasta el presente se basó en o...
