The role of magma mixing in the evolution of the Early Paleozoic calc-alkaline granitoid suites. Eastern magmatic belt, Puna, NW Argentina
(Pergamon-Elsevier Science Ltd, 2017-07)
The outcrops of the Eastern magmatic belt in Puna, NW Argentina, offer an excellent field laboratory to study the interaction processes between magmas of contrasting composition in a plutonic environment. We evaluate the ...
Bimodal chemical evolution of the Galactic disk and the Barium abundance of Cepheids
(International Astronomical UnionLijiang, 2013)
In order to understand the Barium abundance distribution in the Galactic disk based on Cepheids, one must first be aware of important effects of the corotation resonance, situated a little beyond the solar orbit. The thin ...
Large-scale dynamics of Saturn's magnetopause: Observations by Cassini
(American Geophysical Union, 2008-11)
The long-term statistical behavior of the large-scale structure of Saturn’s magnetosphere has been investigated. Established statistical techniques for Jupiter have been applied to the kronian system, employing Cassini ...
The diversity and evolution of pollination systems in large plant clades: Apocynaceae as a case study
(2019-01-23)
Background and Aims: Large clades of angiosperms are often characterized by diverse interactions with pollinators, but how these pollination systems are structured phylogenetically and biogeographically is still uncertain ...
A new invertible bimodal Weibull model
(2023-01-06)
A distribuição Weibull introduzida por Waloddi Weibull em 1951, é um dos modelos mais
utilizados em probabilidade e estatística, pois possui uma expressão simples para a função de
densidade de probabilidade (FDP), função ...
Detailed 40Ar/39Ar dating of geologic events associated with the Mantos Blancos copper deposit, northern Chile
(Springer, 2008-03)
The 40Ar/39Ar geochronological method was
applied to date magmatic and hydrothermal alteration events
in the Mantos Blancos mining district in the Coastal
Cordillera of northern Chile, allowing the distinction of
two ...
Low-resolution spectroscopy of main sequence stars belonging to 12 Galactic globular clusters. I. CH and CN band strength variations
(2010)
Context. Globular clusters show star-to-star abundance variations for light elements that are not yet well understood. The preferred explanation involves a self-enrichment scenario, within which two subsequent generations ...
A theoretical model of strong and moderate El Niño regimes
(Springer, 2019-06-01)
The existence of two regimes for El Niño (EN) events, moderate and strong, has been previously shown in the GFDL CM2.1 climate model and also suggested in observations. The two regimes have been proposed to originate from ...
