Late Pleistocene to Recent Deformation in the Thick‐Skinned Fold‐and‐Thrust Belt of Northwestern Argentina (Central Calchaquí Valley, 26°S)

open access: yesTectonics, 2020
The thick‐skinned fold‐and‐thrust belt on the eastern flank of the Andean Plateau in northwestern Argentina (NWA) is a zone of active contractional deformation characterized by fault‐bounded mountain ranges with no systematic spatiotemporal pattern of ...

Identification and biotechnological characterization of lactic acid bacteria isolated from chickpea sourdough in northwestern Argentina

open access: yesLWT, 2018
Chickpea, a relevant legume worldwide, can be nutritional and functionally improved by fermentation with lactic acid bacteria (LAB). In order to select suitable autochthonous starter cultures, we isolated and identified LAB from kabuli chickpeas ...

Reassessment of mid-Carboniferous glacial extent in southwestern Gondwana (Rio Blanco Basin, Argentina) inferred from paleo-mass transport of diamictites [PDF]

open access: yes, 2013
Late Paleozoic glacial diamictites occur in many localities in western Argentina, indicating that the region was strongly affected by glaciation during the mid-Carboniferous (late Serpukhovian–early Bashkirian).

Cap rock efficiency of geothermal systems in fold-and-thrust belts: Evidence from paleo-thermal and structural analyses in Rosario de La Frontera geothermal area (NW Argentina) [PDF]

open access: yes, 2016
Cap rock characterization of geothermal systems is often neglected despite fracturing may reduce its efficiency and favours fluid migration. We investigated the siliciclastic cap rock of Rosario de La Frontera geothermal system (NW Argentina) in order to

Seismicity and tectonics in Jujuy Province, northwestern Argentina

open access: yesTectonics, 1992
The Portable Array for Numerical Digital Analysis (PANDA) network, a digitally recorded seismic array, operated for nine months in Jujuy province of northwestern Argentina. The network was deployed along the eastern edge of the Altiplano‐Puna plateau in a major N‐S thrust belt that is transitional in style between the thin‐skinned deformation of the ...
