New Insights Into Active Tectonics and Landscape Evolution of the Northernmost Chilean Central Depression

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 ...

An Ordovician Assemblage of Cool Water‐Adapted Paleotropical Ostracods Suggests an Early Psychrosphere

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 ...

New palynological data from the Upper Ordovician of the Precordillera Basin, Argentina: A potential key for understanding the geological history of the Precordillera terrain

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.

Dimorphinites(Ammonoidea, Jurassic, upper Bajocian) in the precordillera of northern Chile [PDF]

Journal of Paleontology, 2011
A new upper Bajocian ammonite assemblage containing the morphoceratidsDimorphinites dimorphus(d'Orbigny) andVigoriceras defrancei(d'Orbigny) is reported from the circum-Pacific area. These ammonites were found at the top of the Torcazas Formation, in the Quebrada San Pedro area, Precordillera of northern Chile.

Glacial Erosion Rates Since the Last Glacial Maximum for the Former Argentino Glacier and Present‐Day Upsala Glacier, Patagonia

Journal of Geophysical Research: Earth Surface, Volume 129, Issue 12, December 2024.
Abstract Recovering the patterns of glacial erosion over time is key to understanding feedbacks between climate and tectonic processes. Glacial erosion rates have been shown to systematically increase worldwide toward the present since the late Cenozoic, a behavior interpreted as the response of glaciers to a cooling and increasingly variable climate ...
