A new constraint on the central Andean rotation pattern from paleomagnetic studies in the southern Subandes of Bolivia
(Pergamon-Elsevier Science Ltd, 2020-03)
New paleomagnetic and anisotropy of magnetic susceptibility (AMS) studies were performed in the southern Subandes of Bolivia in order to assess vertical axis rotations in a poorly studied area. Due to the presence of ...
Paleomagnetism and rock magnetism of the Neoproterozoic Itajai Basin of the Rio de la Plata craton (Brazil): Cambrian to Cretaceous widespread remagnetizations of South America
(ELSEVIER SCIENCE BV, 2011)
A detailed rock magnetic and paleomagnetic study was performed on samples from the Neoproterozoic Itajai Basin in the state of Santa Catarina, Brazil, in order to better constrain the paleogeographic evolution of the Rio ...
Paleomagnetism of Upper Triassic rocks in the Los Colorados hill section, Mendoza province, Argentina
(Pergamon-Elsevier Science Ltd, 2004-12)
Different authors have highlighted a systematic disagreement between Late Carboniferous-Triassic paleomagnetic poles (PPs) for Gondwanaland and Laurasia when they are repositioned in a classical reconstruction prior to the ...
An integrated paleomagnetic and multispecimen paleointensity study from the late Jurassic Zapicán dike swarm (Uruguay)
(Pergamon-Elsevier Science Ltd, 2020-12-22)
A rock magnetic, paleomagnetic and absolute intensity study was conducted on 21 basic dike swarms situated in the Zapicán area (Lavalleja, Uruguay). Paleomagnetic directions revealed mostly normal polarity magnetizations ...
Eocene paleomagnetic pole for South America: Northward continental motion in the Cenozoic, opening of Drake Passage and Caribbean convergence
(American Geophysical Union, 2007-03)
A paleomagnetic study of Eocene volcanic rocks in Patagonia yields high unblocking temperature and high-coercivity magnetizations. Combining these results with those of a previous study on Patagonian Eocene basalts yields ...
Paleomagnetism of Permo-Triassic and Cretaceous rocks from the Antofagasta region, northern Chile
(Elsevier, 2015)
New paleomagnetic data from Permo-Triassic and Late Cretaceous rocks yield a consistent trend of vertical-axis-tectonic-rotations which are consistent with the Central Andean Rotation Pattern (CARP). However, three sites ...
Paleomagnetic Results from the Urupez Paleoindian Site, Maldonado Department, Uruguay
(Center for the Study of the First Americans, 2008-12)
The Urupez site (34° 49′ 15″ S, 55° 19′ 02″ W) is located in the Tarariras Creek basin, ca. 300 m north of the Río de la Plata (Maldonado department, Republic of Uruguay, Figure 1A). Archaeological excavations yielded a ...
