Paleomagnetic study on mid-Paleoproterozoic rocks from the Rio de la Plata craton: Implications for Atlantica
(Elsevier Science, 2015-06)
The first successful paleomagnetic study on middle Paleoproterozoic rocks from the Rio de la Plata craton is reported. Samples collected from the Soca and Isla Mala granitic bodies, located in southern Uruguay, provided ...
Virtual Pole from Magnetic Anomaly (VPMA): A procedure to estimate the age of a rock from its magnetic anomaly only
(ELSEVIER SCIENCE BV, 2009)
Virtual Pole from Magnetic Anomaly (VPMA) is a new multi-disciplinary methodology that estimates the age of a source rock from its magnetic anomaly, taken directly from available aeromagnetic data. The idea is to use those ...
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 ...
Paleogeographic and tectonic evolution of the Pampia Terrane in the Cambrian: New paleomagnetic constraints
(Elsevier Science, 2020-03)
Paleomagnetic, magnetic fabric and rock magnetic studies were carried out in the late Middle to early Late Cambrian Campanario Formation exposed in NW Argentina. The study also presents preliminary results from the Early ...
Paleomagnetic studies on the late Ediacaran - Early Cambrian Puncoviscana and the late Cambrian Campanario formations, NW Argentina: New paleogeographic constraints for the Pampia terrane
(Pergamon-Elsevier Science Ltd, 2016-10)
A magnetofabric and paleomagnetic study was carried out in the Late Ediacaran - Early Cambrian Puncoviscana and the early Late Cambrian Campanario formations, exposed in Santa Victoria Oeste, in northwestern Argentina. Ten ...
Paleosecular variation and absolute geomagnetic paleointensity records retrieved from the Early Cretaceous Posadas Formation (Misiones, Argentina)
(Springer, 2011-04)
The Early Cretaceous may be considered a key period for understanding the evolution of the Earth's magnetic field. Some still unsolved problems are related to the mode of paleosecular variation (PSV) of the Earth's magnetic ...
New Paleomagnetic results and evidence for a geomagnetic field excursion during the pleistocene-holocene transition at Pichincha province, Ecuador
(Elsevier, 2015-03)
Paleomagnetic data from three sedimentary sections in Pichincha province -Quito City (QC), Mullimica (Mu) and El Tingo (ET)- Ecuador (northwestern South America) are reported. Analysis of natural remanent magnetization ...
Magnetização remanescente: um parâmetro crucial para a interpretação e modelamento de anomalias magnéticas em território brasileiro
(Sociedade Brasileira de Geofísica, 2009)
A questão da magnetização remanescente na interpretação de anomalias magnéticas é frequentemente negligenciada, principalmente em função da dificuldade em se lidar com a mesma. Na maioria dos casos, tanto nos trabalhos ...
Paleomagnetic reconnaissance of the grupo diábasico western andes (colombia)
(Departamento de Geociencias, 1986)
A paleomagnetic reconnaissance has been carried out on the Grupo Diabásico of the western Cordillera from the Colombian Andes, between El Tambo and El Penol, Departamento Nariño. The Grupo Diabásico wich is of Cretaceous ...
