An assessment of latest Cretaceous Pycnodonte vesicularis (Lamarck, 1806) shells as records for palaeoseasonality: a multi-proxy investigation [PDF]

open access: yesClimate of the Past, 2018
In order to assess the potential of the honeycomb oyster Pycnodonte vesicularis for the reconstruction of palaeoseasonality, several specimens recovered from late Maastrichtian strata in the Neuquén Basin (Argentina) were subject to a multi-proxy ...

Chemostratigraphy of the Pliensbachian, Puesto Araya Formation (Neuquén Basin, Argentina)

open access: yesGeologica Acta, 2005
In a preliminary attempt to establish an isotope stratigraphy, strontium, carbon and oxygen isotope ratios were determined from marine biogenic carbonates of Pliensbachian age, in the context of scheme of local ammonite Zones correlatable to the European

Transport and Depositional Processes of Neogene Pumice Fragments in a Distal Fluvial System of the Northern Patagonian Foreland (Argentina)

open access: yesBasin Research, Volume 37, Issue 3, May/June 2025.
In this work we analyse the origin, transport, and deposition processes of pumice fragments up to 30 cm in size, deposited in the Northern Patagonian Foreland more than 200 km from the Andean volcanic arc. ABSTRACT There are numerous studies analysing volcaniclastic supply to continental environments in distal areas from source volcanoes.

A HYPOTHETIC SCENARIO FOR THE MIDDLE JURASSIC IN THE SOUTHERN PART OF THE NEUQUÉN BASIN, ARGENTINA

open access: yesPublicación Electrónica de la Asociación Paleontológica Argentina, 2015
A hypothetic scenario for the Middle Jurassic in the southern part of the Neuquén Basin, is proposed on the basis of sedimentary facies and palynological data obtained from the study of eight stratigraphic sections.

Hierarchy of bounding surfaces in aeolian sandstones of the Jurassic Tordillo Formation (Neuquén Basin, Argentina)

open access: yesGeologica Acta, 2005
The Tordillo Formation is a continental clastic unit deposited in the Neuquén Basin during the Late Jurassic. This paper discusses the stratigraphy of the succession outcropping at the Quebrada del Sapo, with emphasis on the origin, dimensions and ...

European Arid Anomaly Explained With Southward Drift of Eurasia During the Late Jurassic Polar Shift

open access: yesGeochemistry, Geophysics, Geosystems, Volume 26, Issue 2, February 2025.
Abstract The sedimentary successions of several basins in Europe show evidence of widespread Late Jurassic aridification that is considered a long‐standing conundrum in paleoclimate modeling. The distinctive feature of this event is that it appears concentrated in a discrete time interval between the Kimmeridgian (Late Jurassic) and the Berriasian ...

Unconfined gravity current interactions with orthogonal topography: Implications for combined‐flow processes and the depositional record

open access: yesSedimentology, Volume 72, Issue 1, Page 67-99, January 2025.
ABSTRACT Turbidity current behaviour is affected by interactions with seafloor topography. Changes in flow dynamics will depend on the orientation and gradient of the topography, and the magnitude and rheology of the incoming flow. A better understanding of how unconfined turbidity currents interact with topography will improve interpretations of the ...

PALEOECOLOGY AND ENVIRONMENTS OF THE CRETACEOUS SEDIMENTARY BASINS OF PATAGONIA (SOUTHERN ARGENTINA)

open access: yesPublicación Electrónica de la Asociación Paleontológica Argentina, 2015
The evolution of the continental and marine Cretaceous basins of Patagonia and adjacent areas (Chilean marine strip, basins developed around the Malvinas Islands, and the austral extremity of South America) is here considered, taking into account their ...

Morphological characterization of an exceptionally preserved eolian system: the Cretaceous Troncoso Inferior Member in the Neuquén Basin (Argentina)

open access: yesLatin American Journal of Sedimentology and Basin Analysis, 2021
The aim of this study was to characterize in detail the exceptionally preserved eolian morphology within the uppermost section of the Lower Cretaceous Troncoso Inferior Member at the classic outcrop locality of Loma La Torre in northern Neuquén ...
