A high-resolution record of environmental changes from a Cretaceous-Paleogene section of Seymour Island, Antarctica
(Elsevier Science, 2020-06)
A high-resolution sedimentological and palynological study was performed in combination with biomarker-based organic geochemical temperature proxies TEX86 and MBT′/CBT, on a 7.4-m-thick continuous section straddling the ...
Interactive comment on “Surface-circulation change in the Southern Ocean across the Middle Eocene Climatic Optimum: inferences from dinoflagellate cysts and biomarker paleothermometry” by Margot J. Cramwinckel et al.
(Copernicus Publications, 2019-05-28)
The Middle Eocene Climatic Optimum (MECO) is a global warming event at about 40 Ma that interrupted the long-term Cenozoic cooling trend. Up to now only a few studies have focused with enough resolution to evaluate the ...

(Asociacion Paleontologica Argentina, 2004-12)
El análisis palinológico aplicado a muestras de afloramiento de la Formación Lotena (datos integrados del perfil Portada Covunco y registros previos de perfil arroyo Picún Leufú) permitió determinar 29 taxones de esporomorfos ...
Quistes de dinoflagelados del Cenozóico de la Cuenca del Colorado, ArgentinaCenozoic dinoflagellate cytests from the Colorado basin, Argentina
(Asociacion Paleontologica Argentina, 2001-12)
Cenozoic sediments from the well Cx-l of offshore Colorado Basin were studied. The dinoflagellate cysts assemblages are diverse and well preserved praviding stratigraphic control for the section. Selected dinoflagellate ...
Early to middle Holocene palaeoenvironmental reconstruction of the Beagle Channel (southernmost Argentina) based on terrestrial and marine palynomorphs
(Wiley Blackwell Publishing, Inc, 2018-10)
This paper presents the main palaeoenvironmental results obtained from a site located in the western sector of the Beagle Channel, Isla Grande de Tierra del Fuego, southernmost Argentina. The palynological analysis performed ...
Middle-Late Holocene palynology and marine mollusks from Archipiélago Cormoranes area, Beagle Channel, southern Tierra del Fuego, Argentina
(Elsevier Science, 2009-03)
The palynology and marine mollusks of a marine sequence from Río Ovando (54° 51′ S, 68° 35′ W), Archipiélago Cormoranes, Beagle Channel, has been studied in order to reconstruct paleoenvironmental conditions during the ...
Past environmental changes during the Late Holocene sea-level fall (last 2.7 Ka) at Bahía Samborombón, NE coastal plain (Argentina)
(Pergamon-Elsevier Science Ltd, 2018-08)
Here we present a reconstruction of vegetation history and environmental changes at the central zone of Bahía Samborombón during the Late Holocene sea-level regressive phase (last 2.7 Ka) corresponding to MIS 1. This study ...
Palinología del Paleogeno tardío-Neo geno temprano, pozo Aries x-l, Plataforma Continental Argentina, Tierra del Fuego
(Asociacion Paleontologica Argentina, 2000-06)
Nineteen cutting samples from the Aries x-I well, drilled in the Argentine continental shelf, offshore Tierra del Fuego, were analized for palynology. Marine and terrestrial palynomorph assemblages, fairly well preserved, ...
