Modeling the Offshore Export of Subantarctic Shelf Waters From the Patagonian Shelf
(Blackwell Publishing Ltd, 2018-07)
It has been suggested that the Subtropical Shelf Front (STSF) could be a preferential site for the detrainment of Subantarctic Shelf Water (SASW) and related planktonic shelf species onto the open SW Atlantic Ocean. The ...
The offshore basement of Perú: evidence for different igneous and metamorphic domains in the forearc
(Elsevier, 2013-02)
As a result of new studies carried out in the offshore of Perú during the exploration and hydrocarbon evaluation of the forearc basins, new U–Pb SHRIMP and TIMS in zircons and some Ar–Ar data were obtained in the metamorphic ...
Basement structural control in the Magallanes-Malvinas Fold and Thrust Belt, offshore Argentina
(Pergamon-Elsevier Science Ltd, 2020-11)
In this study, we examine the external part of the Magallanes-Malvinas Fold and Thrust Belt in offshore areas, including a portion in Tierra del Fuego onshore, in southern South America. Our investigations focus on the ...
New insights on the Paleogene dinoflagellate cyst genera Enneadocysta and Licracysta gen. nov. based on material from offshore eastern Canada and southern Argentina
(Micropaleontology Press, 2006-12)
Enneadocysta is a biostratigraphically important Paleogene dinoflagellate cyst genus. Its original interpretation as a partiform gonyaulacoid (thus belonging to the gonyaulacalean suborder Cladopyxiineae) was based on the ...
Spatio-temporal variations in the Mesozoic sedimentary record, Golfo San Jorge Basin (Patagonia, Argentina): Andean vs. cratonic sources
(Pergamon-Elsevier Science Ltd, 2020-03)
The continental succession of the Cretaceous Chubut Group (Aptian-Maastrichtian) in the Golfo San Jorge Basin (GSJB), central extra-Andean Patagonia (Argentina) contains a high proportion of volcaniclastic input derived ...
Fine-grained distal deposits of a mixed siliciclastic-carbonate marine system: Origin of mud and implications on mixing processes
(Society for Sedimentary Geology, 2022-03)
Mixed siliciclastic-carbonate sediments in the distal settings of marine systems (i.e., offshore and basin areas) are the result of the complex interaction between production of benthic and pelagic biogenic carbonates and ...
Mid-latitude Paleogene dinoflagellate cysts from offshore Santa Catarina (Pelotas Basin, Southern Brazil): Taxonomy and biochronostratigraphy
(Elsevier, 2021-10-06)
Palynological assemblages have been reported in pre-Quaternary deposits of the Pelotas Basin, except in the Santa Catarina Platform, where micropaleontological information is still restricted to calcareous microfossils. ...
Rifting evolution of the Malvinas basin, offshore Argentina: New constrains from zircon U–Pb geochronology and seismic characterization
(Elsevier Science, 2019-11)
The Malvinas basin, emplaced offshore southern Patagonia, is an asymmetric extensional basin formed by NNW-striking faults. In this contribution we present a review and updated structural framework for the Malvinas basin, ...
Trace elements in subantarctic false killer whale (Pseudorca crassidens) tissues, including the skin as an offshore bioindicator
(Springer Heidelberg, 2021-06)
On a global scale, cetaceans are recognized well indicators of marine ecosystem health. Trace elements accumulate in their bodies and potentially constitute a toxicological threat. Here, the concentrations of essential Se; ...
