Tectono-sedimentary cenozoic evolution of the el habt and ouezzane tectonic units (External rif, morocco)
(MDPI AG, 2020-12-03)
An interdisciplinary study based on lithostratigraphic, biostratigraphic, petrographic and mineralogical analyses has been performed in order to establish the Cenozoic tectono-sedimentary evolution of the El Habt and ...
Cannosphaeropsis quattraocchiae, a new species of dinoflagellate cyst from the mid Cenozoic of the Colorado Basin, Argentina
(Micropaleontology Press, 2001-12)
Cannosphaeropsis quattrocchiae n. sp., from the Cenozoic of the Colorado Basin, resembles two other species, Cannosphaeropsis utinensis and Cannosphaeropsis passio, and has been confused with the former. However, separation ...
Mesozoic and Cenozoic microbiotas from eastern Antarctic Peninsula: adaptation to a changing palaeoenvironment
(Advances in Polar Science, 2019-09)
A compiled selected literature on some groups of microfossils of the Mesozoic and Cenozoic of the James Ross Basin, eastern Antarctic Peninsula, is presented here, in order to show how the microbiota has been modified over ...
Revised Timing of Cenozoic Atlantic Incursions and Changing Hinterland Sediment Sources during Southern Patagonian Orogenesis
(GEOSCIENCEWORLD, 2020-06)
New detrital zircon U-Pb geochronology data from the Cenozoic Magallanes-Austral Basin in Argentina and Chile similar to 51 degrees S establish a revised chronostratigraphy of Paleocene-Miocene foreland synorogenic strata ...
Cenozoic forearc basin sediments in Southern Peru (15–18°S): Stratigraphic and heavy mineral constraints for Eocene to Miocene evolution of the Central Andes
(ElsevierNL, 2011-05)
A large sedimentary forearc basin developed in Cenozoic times between the present-day Coastal Cordillera and the Western Cordillera of the Central Andes, called Moquegua basin in southern Peru. The basin is filled by ...
Deciphering the late paleozoic–cenozoic tectonic history of the inner central andes forearc: an update from the salar de Punta Negra basin of Northern Chile
(Frontiers Media, 2022)
We integrated new and existing geological, geochronological, thermochronological, and two-dimensional (2D) seismic data from the Salar de Punta Negra Basin to define the Late Paleozoic-Cenozoic tectonic evolution of the ...
Deciphering the Late Paleozoic–Cenozoic Tectonic History of the Inner Central Andes Forearc: An Update From the Salar de Punta Negra Basin of Northern Chile
(Frontiers Media S.A., 2022-01)
We integrated new and existing geological, geochronological, thermochronological, and two-dimensional (2D) seismic data from the Salar de Punta Negra Basin to define the Late Paleozoic–Cenozoic tectonic evolution of the ...
Magnetostratigraphy and magnetic parameters in Quaternary sequences of Balcarce, Argentina. a contribution to understand the magnetic behaviour in cenozoic sediments of South America
(Elsevier, 2017-06)
The South America Loess plateau covers a large part of Argentina. In this country, the Balcarce Hills represent at the moment a poorly studied area from a stratigraphic and paleoenvironmental point of view. This area is ...
Correlation of late Cenozoic sequences of southeastern Buenos Aires province: Biostratigraphy and magnetostratigraphy
(Pergamon-Elsevier Science Ltd, 2009-07)
Correlations among stratigraphic sequences of the continental late Cenozoic of southeastern Buenos Aires province have been historically based on lithostratigraphy and paleontological content. Recent magnetostratigraphic ...
Cenozoic diatreme field in Chubut (Argentina) as an evidence of phreatomagmatic volcanism accompanied with extensive Patagonian plateau basalt volcanism?
(Int Union Geological Sciences, 2007-09)
In Patagonia, Argentina, at the northern border of the Patagonian mafic Cenozoic plateau lava fields newly discovered diatremes stand about 100 m above the surrounding plane. These diatremes document phreatomagmatic episodes ...
