Mid Campanian‐Lower Maastrichtian magnetostratigraphy of the James Ross Basin, Antarctica: Chronostratigraphical implications
The James Ross Basin, in the northern Antarctic Peninsula, exposes which is probably the world thickest and most complete Late Cretaceous sedimentary succession of southern high latitudes. DespiteExpand

MAGNETOSTRATIGRAPHY OF AN UPPER CRETACEOUS SUCCESSION OF JAMES ROSS BASIN, ANTARCTICA
A magnetostratigraphic study was carried out in three Upper Cretaceous sections exposed in the SE area of James Ross Basin, Antarctic Peninsula. We present preliminary results of paleomagnetism, rockExpand

Magnetostratigraphy of the Rabot Formation, Upper Cretaceous, James Ross Basin, Antarctic Peninsula
Problems of endemism and diachronous extinctions make global correlation of coeval strata in the mid Campanian-Maastrichtian of the James Ross Basin problematic. To provide a more preciseExpand

Paleomagnetic confirmation of the “unorthodox” configuration of Atlantica between 2.1 and 2.0 Ga
Abstract The paleogeographic evolution of the Rio de la Plata Craton during the Precambrian poses important questions regarding its participation in the Atlantica continent and ColumbiaExpand

U-PB geochronology and magnetostratigraphy of a north Patagonian syn-orogenic Miocene succession: Tectono-stratigraphic implications for the foreland system configuration
Abstract The syn-orogenic Miocene deposits of the Patagonian Foreland System were the focus of numerous works in the latest years, due to their central role in the comprehension of theExpand

Large paleomagnetic declination anomalies in the Cerro Nevado (Snow Hill) Island, Antarctic Peninsula: evidence of hidden tectonic rotations?
We report anomalous paleomagnetic directions obtained in magnetostratigraphic studies carried out on Cretaceous marine sedimentary rocks of the Marambio Group, southeast James Ross Basin, at theExpand
Late Cretaceous paleogeography of the Antarctic Peninsula: New paleomagnetic pole from the James Ross Basin
Two paleomagnetic poles of 80 and 75 Ma have been computed from 191 to 123 paleomagnetic samples, respectively, of the marine sedimentary units of the Upper Cretaceous Marambio Group exposed in theExpand

Coniacian-Campanian magnetostratigraphy of the Marambio Group: The Santonian-Campanian boundary in the Antarctic Peninsula and the complete Upper Cretaceous – Lowermost Paleogene
Abstract Recent magnetostratigraphic works from different areas of the James Ross Basin have expanded on chronostratigraphic studies previously based on ammonite, palynomorph and nanoplanktonExpand
