Provenance of dust to Antarctica: A lead isotopic perspective
(American Geophysical Union, 2016-03)
Antarctic ice preserves an ~800 kyr record of dust activity in the Southern Hemisphere. Major efforts have been dedicated to elucidate the origin of this material in order to gain greater insight into the atmospheric dust ...
Variations of geomagnetic cutoff rigidity in the southern hemisphere close to 70°W (South-Atlantic Anomaly and Antarctic zones) in the period 1975–2010
(Elsevier Ltd, 2019)
© 2018 COSPARWe report the existence of rapid variations in (effective) geomagnetic cutoff rigidity (Rc) between the equatorial and Antarctic zones adjacent to the Andes Mountains, revealed by the variation rate of geomagnetic ...
Geographic provenance of aeolian dust in East Antarctica during Pleistocene glaciations: preliminary results from Talos Dome and comparison with East Antarctic and new Andean ice core data
(Pergamon-Elsevier Science Ltd, 2010-01)
The strontium and neodymium isotopic signature of aeolian mineral particles archived in polar ice cores provides constraints on the geographic provenance of dust and paleo-atmospheric circulation patterns. Data from different ...
Isotopic constraints on the source of Argentinian loess - With implications for atmospheric circulation and the provenance of Antarctic dust during recent glacial maxima
(Elsevier Science, 2003-07)
We present rare-earth element (REE) and Sr-Nd isotopic data for Argentinian loess (28-38°S) with two aims: (1) to examine the source regions of Argentinian loess and the constraints that these put on palaeo-wind directions; ...
Glacial/interglacial changes of Southern Hemisphere wind circulation from the geochemistry of South American dust
(Elsevier Science, 2017-07)
The latitudinal displacement of the southern westerlies and associated climate systems is a key parameter for understanding the variations of Southern Hemisphere atmospheric circulation during the Late Quaternary Period. ...
Historia de la medicina peruana en el siglo XX (Tomo II)
(Fondo Editorial UNMSMFondo Editorial UNMSM, 2000)
A review of the Famatinian Ordovician magmatism in southern South America: Evidence of lithosphere reworking and continental subduction in the early proto-Andean margin of Gondwana
(Elsevier Science, 2018-12)
Along the proto-Pacific margin of Gondwana, from Venezuela to northeastern Patagonia, the Early–Middle Ordovician Famatinian orogeny was the first orogenic event following assembly of the supercontinent. Previous isotope ...
