Review of the Cambrian Stratigraphy of the Argentine Precordillera

Geologica Acta, 2003
The Cambrian rocks of the Argentine Precordillera are analyzed and updated providing a new stratigraphic interpretation. The lithostratigraphic assemblages provide evidence that the Precordilleran Cambrian Basin was a rimmed platform.

Characterization of Southern Peru Hydrothermal Systems: New Perspectives for Geothermal Exploration Along the Andean Forearc

Geochemistry, Geophysics, Geosystems
This study provides a comprehensive characterization of various hydrothermal systems in Southern Peru ranging from the faulted Precordillera's steep topography up to the volcanic High Cordillera (>4,000 m asl).

Structural and tectonic assessment of the western Huincul High, Neuquén Basin (Argentina)—The role of structural inheritance and mechanical stratigraphy in inversion systems

Basin Research, Volume 35, Issue 6, Page 2140-2164, December 2023., 2023
3D visualisation of the Upper Triassic, syn‐extension, top unit 1 showing the key inversion anticlines in the western Huincul High (Neuquen Basin). Abstract The Neuquén Basin is a major Mesozoic sedimentary depocentre located in the retroarc foreland of the Argentinian Andes. The basin hosts world renowned inversion systems that have been the target of

Are Volatiles From Subducted Ridges on the Pampean Flat Slab Fracking the Crust? Evidence From an Enhanced Seismicity Catalog

Geochemistry, Geophysics, Geosystems, Volume 24, Issue 10, October 2023., 2023
Abstract Seamounts and ridges are often invoked to explain subduction‐related phenomena such as flat slab generation, but the extent of their involvement remains controversial. An analysis of seismicity in the region of the Pampean flat slab through an application of an automated catalog generation algorithm resulted in 35,924 well constrained local ...

Localization of Deformation in a Non‐Collisional Subduction Orogen: The Roles of Dip Geometry and Plate Strength on the Evolution of the Broken Andean Foreland, Sierras Pampeanas, Argentina

Tectonics, Volume 42, Issue 8, August 2023., 2023
Abstract The southern Central Andes (SCA, 27°–40°S) exhibit a complex deformation pattern that is influenced by multiple factors, including the present‐day dip angle of the subducting oceanic Nazca plate and the influence of inherited heterogeneities in the continental South American plate. This study employs a data‐driven geodynamic workflow to assess

Class Trilobita (including agnostoids) from Argentine Precordillera

Biogeographia – The Journal of Integrative Biogeography, 2023
This data paper inventories the records of 1763 trilobites (including agnostoids) from the Middle Cambrian inner and outer platform of the Argentine Precordillera (San Juan and Mendoza provinces). They were collected by Dr. Osvaldo Bordonaro and his colleagues between 1994 and 2013 and studied within the framework of scientific research.

Some middle Cambrian agnostoids from the Precordillera Argentina.

Spanish Journal of Palaeontology, 2022
Agnostoid trilobites are described from Middle Cambrian sediments in the Precordillera of Mendoza and San Juan provinces. The following taxa occur at Solitario Hill, Mendoza: Clavagnostus canotensis, Tomagnostella exsculpta, Agnostus exsulatus, Agnoslus? sp., Oedorhachis australis, Ptychagnostus aculeatus and Ammagnostus sp.

Machaeridians from the Middle and Upper Ordovician of the Argentine Precordillera

Geological Journal, 2012
The machaeridians are marine Palaeozoic annelids, which developed a dorsal skeleton composed of calcite sclerites, achieving a world‐wide distribution from the Early Ordovician to the Middle Permian. The absence of records from this group is notable in Argentina in spite of intense studies of Palaeozoic rocks.

Lower Darriwilian radiolarians from the Argentine Precordillera

Geobios, 2009
Abstract The first radiolarians discovered in the Ordovician of the Argentinian Precordillera are reported. The material is associated with conodonts indicating the upper part of the Lenodus variabilis Biozone (Lower Darriwilian, Da1-2). The low diversity radiolarian fauna shows similarities with Middle Ordovician radiolarians from the Akzhal ...
