Hydrothermal alteration and its effects on the magnetic properties of Los Pelambres, a large multistage porphyry copper deposit
(Elsevier Science BV., 2016)
The Los Pelambres porphyry copper deposit is located 190 km north of Santiago, Chile. A paleomagnetic and mineralogical study was conducted at this deposit to determine the effects of hydrothermal alteration on the magnetic ...
Simple hysteresis loop model for rock magnetic analysis
(Springer, 2020-01)
A simple phenomenological model founded on Lorentzian functions is evaluated on the first derivative of magnetic hysteresis loops from several artificial samples with iron oxide/oxyhydroxide mixtures imitating natural ...
Palaeomagnetism, rock magnetism and AMS of the Cabo Magmatic Province, NE Brazil, and the opening of South Atlantic
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
P>Reconstruction of the South Atlantic opening has long been a matter of debate and several models have been proposed. One problem in tracing properly the Atlantic history arises from the existence of a long interval without ...
Emplacement mechanism of the main granite pluton of the Lavras do Sul intrusive complex, South Brazil, determined by magnetic anisotropies
(ELSEVIER SCIENCE BV, 2009)
Magnetic fabric and rock magnetism studies were performed on apparently isotropic granite facies from the main intrusion of the Lavras do Sul Intrusive Complex pluton (LSIC, Rio Grande do Sul, South Brazil). This intrusion ...
Linking Speleothem And Soil Magnetism In The Pau D'alho Cave (central South America)
(Amer Geophysical UnionWashington, 2016)
Magnetic polarity zonation within the El Teniente copper–molybdenum porphyry deposit, central Chile
(Springer, 2010)
El Teniente porphyry copper deposit, the world’s
greatest intrusion-related Cu–Mo ore body, is hosted within
basaltic–andesitic volcanic and gabbroic rocks (mafic complex).
This ore body is strongly affected by multiple ...
Paleomagnetic and paleoclimatic investigation at Laguna Melincue (Pampean Plains, Argentina): preliminary results
(Springer, 2017-04)
Laguna Melincué is a shallow lake located in Santa Fe Province, Argentina (33°41′27.8″S, 61°31′36.5″W). The catchment area is around 1495 km2 and it is located in the Pampean Plains. It was reduced to 678 km2 by the ...
Rock magnetism in two loess–paleosol sequences in Córdoba, Argentina
(Springer, 2014-11)
This work presents new rock magnetic results along two loess–paleosol profiles in nearby locations in Argentina. The main objective of this study is to compare the magnetic signals and mineral content of two profiles and ...
Magnetostratigraphy and mid-palaeolatitude VGP dispersion during the Permo-Carboniferous Superchron: results from Parana Basin (Southern Brazil) rhythmites
(WILEY-BLACKWELLHOBOKEN, 2012)
A detailed magnetostratigraphic and rock-magnetism study of two Late Palaeozoic rhythmite exposures (Itu and Rio do Sul) from the Itarare Group (Parana Basin, Brazil) is presented in this paper. After stepwise alterning-field ...
