Magnetic petrology of the Devonian Achala Batholith, Argentina: Titanohaematite as an indicator of highly oxidized magma during crystallization and cooling
(Wiley Blackwell Publishing, Inc, 2008-12)
Devonian magmatism in the Eastern Sierras Pampeanas (Córdoba, Argentina) is represented by elliptical, porphyritic, batholithic, late- to post-orogenic monzogranites emplaced in a metamorphic-plutonic basement. Two groups ...
Timing of rifting in the southern Gulf of California and its conjugate margins: Insights from the plutonic record
(Geological Society of America, 2015-05-01)
The Gulf of California is a young example of crustal stretching and transtensional shearing leading to the birth of a new oceanic basin at a formerly convergent margin. Previous studies focused along the southwestern rifted ...
Magnetic anisotropy and valence states in L a2 C o1-x M n1+x O6 (x≈0.23) thin films studied by x-ray absorption spectroscopy techniques
(American Physical Society, 2017-06)
X-ray absorption spectroscopy was used to determine the valence state in La2Co1-xMn1+xO6 (x≈0.23) thin films. We found that in spite of the nonstoichiometry, Co is in a divalent state while Mn ions show a mixed valence ...
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 ...
Magnetic monitoring of anthropogenic pollution in Antarctic soils (Marambio Station) and the spatial-temporal changes over a decade
(Elsevier Science, 2021-08)
Marambio Station is one of the most important human settling in the Antarctic Peninsula, which has been polluted by human activities since the 1970s. Following the first magnetic monitoring in Antarctic soils (austral ...
An environmental magnetism approach to assess impacts of land-derived sediment disturbances on coral reef ecosystems (Cartagena, Colombia)
(Pergamon-Elsevier Science Ltd, 2018-06)
We used environmental magnetism methods to study recently deposited marine sediments from the estuarine ecosystems on the Caribbean coast of Colombia. Cartagena region has undergone an increasing sediment load during the ...
Crystal and magnetic structure and cation distribution of Mn2-xV1+xO4 spinels (x = 0, 1/3 and 1)
(Pergamon-Elsevier Science Ltd, 2009-07)
We synthesized the spinel-type compounds belonging to the Mn2-xV1+xO4 series with x = 0, 1/3 and 1 as polycrystalline powders. Crystal and magnetic structures were refined using synchrotron X-ray and neutron powder ...
