Magnetic properties of the remagnetized Middle-Ordovician limestones of the Ponón Trehué Formation (San Rafael Block, central-western Argentina): Insights into the Permian widespread Sanrafaelic overprint
(Pergamon-Elsevier Science Ltd, 2016-10)
The widespread Sanrafaelic remagnetization reset most of the early Cambrian to mid-Ordovician carbonate platform of the Argentine Precordillera and the calcareous units of the San Rafael Block. We conducted a detailed ...
Magnetic susceptibility mapping of the Cambrian El Hongo pluton, Eastern Sierras Pampeanas, Argentina
(Springer, 2017-04)
A map of bulk magnetic susceptibility was obtained on El Hongo trondhjemite, a small Cambrian pluton intruding the metamorphic basement in Eastern Sierras Pampeanas, Argentina, based on systematic magnetic susceptibility ...
Magnetic properties related to hydrothermal alteration processes at the Escondida porphyry copper deposit, northern Chile.
(2014)
Fluid–rock interaction related to the circulation of hydrothermal fluids can strongly modify the physicochemical properties of wall rocks in porphyry Cu deposits. These processes can also produce compositional and textural ...
Suscettività magnetica e assetto strutturale nelle Ande in Tierra del FuegoMagnetic susceptibility and structural setting in the Tierra del Fuego Andes
(Società Geologica Italiana, 2009-12)
With the aim of studying the tectonic evolution of the Fueguian Andes,the magnetic susceptibility tensor was measured on sample rocks of the Lemaire and Yahgán Fms outcrop in the area between Paso Garibaldi and Canal Beagle ...
Absolute Thellier paleointensities from Ponta Grossa dikes (southern Brazil) and the early Cretaceous geomagnetic field strength
(INST GEOPHYSICS UNAM, 2009)
We report a detailed rock magnetic and Thellier paleointensity study from similar to 130.5 Ma Ponta Grossa Dike Swarms in Southern Brazil. Twenty-nine samples from seven cooling units were pre-selected for paleointensity ...
Geological and geophysical methods relevant to decipher the structure and emplacement of granites: Insights from the Calmayo pluton (Eastern Sierras Pampeanas, Argentina)
(Pergamon-Elsevier Science Ltd, 2021-03)
In this paper, the evolution of the fabric and 3D geometry of the Calmayo trondhjemitic pluton (512.1 ± 3.4 Ma; Sierra Chica, Córdoba, Argentina) is analyzed using Anisotropy of Magnetic Susceptibility (AMS) measurements ...
How fast was the Matuyama-Brunhes geomagnetic reversal? A new subcentennial record from the Sulmona Basin, central Italy
(Oxford Univ Press, 2016-02-01)
A recent study of the Matuyama-Brunhes (M-B) geomagnetic field reversal recorded in exposed lacustrine sediments from the Sulmona Basin (Italy) provided a continuous, high-resolution record indicating that the reversal of ...
