I am currently works at the Instituto de Geología y Paleontología at CCT Conicet-Cenpat. I do research in geology and basin analysis. My current project is 'Tectonostratigraphic evolution of the northern Neogene foreland depocenter of the Austral (Magallanes) Basin' studying the impact of the Andean uplift on the Austral-Magallanes basin their tectonic, sedimentological and paleoclimate implications.
Detrital zircon U–Pb geochronology is a widely used technique for interpreting sedimentary provenance in basin systems. This, combined with detailed sedimentary facies interpretation and stratigraphy evolution, has been extensively applied in foreland basin settings to understand tectonic processes by tracking the exposure and erosion of distinct s...
The early–middle Miocene continental Cerro Boleadoras Formation (CBF) crops out in the area of Cerro Boleadoras and Cerro Plomo on the western slope of the Meseta del Lago Buenos Aires, northwestern Santa Cruz Province, Argentina. The lower levels of the CBF consist of laterally extensive medium to pebbly sandstone beds with trough cross-bedding, i...
Eocene paleofloras of Patagonia are diverse and increasingly known. A new assemblage of fossil wood has been recovered from Eocene sediments in Corcovado, western Argentinean Patagonia. The lithological succession (formerly Arroyo Lyn Formation sensu Pesce 1979) is correlated with the Huitrera Formation. The specimens were mostly found embedded in...
Despite their geodynamic significance, the stratigraphy and paleoenvironments of the lower-middle Miocene clastic deposits, genetically related to subduction-driven lithospheric processes at the latitude of the Chile Triple Junction are poorly known. These beds, outcropping along the foothills of the Southern Patagonian Andes in the northwestern ed...
Lago Posadas is located at the foot of the Southern Patagonian Andes, in southwestern Argentina, where the early Miocene Santa Cruz Formation (SCF) shows thick and laterally continuous exposures. This region has been scarcely explored for fossil vertebrates since the first efforts by J.B. Hatcher in 1898-99. In this contribution, we performed sedim...
The continental early Miocene Santa Cruz Formation (SCF) is widely distributed in southern Patagonia. It fossil mammals comprise the basis of the Santacrucian Land Mammal Age. Fossil prospecting of exposures along the southern escarpment of Río Chalía have been neglected until now. They represent the greatest known aerial exposure and sedimentary t...
Sedimentologic studies together with preliminary anisotropy of magnetic susceptibility (AMS) analysis were carried out in a very particular and intriguing Lower Cretaceous depocenter in the northern Austral-Magallanes basin, in order to elucidate its geodynamic setting. Aptian-Albian regressive sequences from the coastal Río Belgrano Formation and...
The prime objective of this project is to improve our understanding of the interrelations between Andean-type orogenic uplift and subsidence and sedimentation patterns in retro-arc foreland basins. Several types of data and variables are considered, such as deformation processes, orographic uplift, exhumation and erosion of source areas, accommodation space dynamics, epiclastic and pyroclastic sediment production and dispersion, and stacking patterns and chronology of deposition. The Neogene foreland depocenter of the northern Austral or Magallanes Basin (from 46° 30'S to 48° 20'S) was selected as a case study because it shows a well-exposed, thick Neogene sedimentary column, which is supposed to be synchronous to the main phase of Neogene Andean uplift. Facies and stratigraphic analysis, geochronology, sandstone provenance and paleosol-based paleoclimate reconstructions are being used to reconstruct paleoenvironments of deposition, sedimentation rates and source rock composition. These data, in combination with thermochronologic and structural information from the adjacent Andes will allow relating phases of Andean uplift with sedimentary dynamics of the foreland basin and its associated paleoclimatic changes.
