Pinturas rupestres y contextos arqueológicos de la precordillera de Arica (extremo norte de Chile)
Estudios Atacameños, 2013 Las evidencias de los sitios Pampa El Muerto 3 (PM-3), Pampa El Muerto 8 (PM-8) y Tangani 1 (TAN-1) permiten reafirmar que el arte rupestre de la precordillera en el extremo norte de Chile se asocia a una colonización más bien tardía de este espacio ...

The Role of Orogenic Collapse on Tectonic Inheritance of Passive Continental Margins
Tectonics, Volume 44, Issue 1, January 2025.Abstract The break‐up and drift of continents is governed by the reactivation of structures in the lithosphere that occur in preference to formation of new structures during rifting. Numerical analyses indicate that mantle heterogeneities should be a first‐order control on tectonic inheritance; however, the importance of mantle relative to crustal ...

The Spatial And Temporal Evolution Of The Argentine Precordillera At 30Xc2Xbas: Shortening Over A Shallow Slab [PDF]
, 2012 The Argentine Precordillera is a foreland fold-and-thrust-belt in western Argentina that overlies the central Chilean flat slab region of the subducting Nazca plate. The Precordillera has accommodated shortening over the past ~20 million years; over this

Antropologías del Sur, 2019 Las formas en que las personas explican los desastres “naturales”, el rol que juega la ciencia, los expertos y el saber “técnico”, permiten dar cuenta de cómo el aluvión de 1993 no se puede entender solamente desde la naturaleza.

Tectonics, Volume 44, Issue 1, January 2025.Abstract Active deformation and landscape evolution in North Chilean forearc involve multiscale tectonic processes, such as crustal thickening causing orogenic‐scale uplift and faulting modulating the mountain‐front landscape. In the Central Depression, faults redirecting Quaternary drainages are poorly understood due to their subtle surface ...

Stratigraphy, 2013 Biostratigraphic data from the Precordillera Basin have traditionally been analyzed to contribute to the understanding of its biogeographic evolution as an allochthonous microcontinent accreted to the western Gondwanan margin in the Middle-Late Ordovician.

Island Arc, Volume 34, Issue 1, January/December 2025.ABSTRACT An ostracod assemblage from the Late Ordovician (Katian) Phu Ngu Formation of northern Vietnam, South China paleoplate, yields typical Baltic and Laurentian‐affinity genera together with some endemic forms. Detailed paleontological and sedimentary analysis of the Phu Ngu Formation suggests it was deposited in a deeper marine forearc setting ...

Upper Ordovician (Sandbian) bryozoan fauna from Argentine Precordillera
Journal of Paleontology, 2012 A stenolaemate bryozoan fauna containing 20 species belonging to 18 genera is described from the Las Plantas and Las Aguaditas formations (Upper Ordovician, Sandbian) in San Juan Province, Precordillera of Western Argentina. One genus with one species is new:Argentinodictya lenticulatan. gen. n. sp. (Cryptostomata, Ptilodictyina). Four species are new:
