Petrogenesis of shield volcanism from the Juan Fernández Ridge, Southeast Pacific: Melting of a low-temperature pyroxenite-bearing mantle plume
(Elsevier Ltd, 2019)
© 2019 Elsevier LtdThe Juan Fernández Ridge (JFR) is an age-progressive volcanic chain (∼800 km long) related to a fixed mantle plume in the Southeast Pacific offshore central Chile. The high 3He/4He ratio (up to 18 times ...
Perovskite MgSiO3 at Earth's mantle conditions.
(Sociedade Brasileira de Pesquisas em Materiais.Campos do Jordão, 2013-09-29)
In the last decades, the study of high pressure materials allowed a great comprehension
of Earth's internal structure. Recently, a great attention has been given to the
phenomenology of the lower mantle, with depth between ...
Tipologia de zircao e razao inicial Sr87/86Sr em series granitoides
(1990-12-01)
Sr87/86Sr initial ratio data based on the isochrons from 22 granitoid complexes of Brasiliano age (Late Precambrian) from S and E Brazil are presented. The complexes have been classified into different rock series with the ...

Point defects in MgO.
(Sociedade Brasileira de Pesquisas em Materiais.Campos do Jordão, 2013-09-29)
The Earth's mantle is composed mainly by MgO, known as periclase, which has a simple rock-salt structure with perfectly octahedral cation sites. Point defects in this material, such as vacancies and isolated impurities, ...

Interpreting chemical compositions of small scale basaltic systems: A review
(Elsevier, 2016)
Small scale basaltic magmatic systems occur in all of the major tectonic environments of planet Earth and are characteristically expressed at the Earth's surface as fields of small monogenetic cones. The chemical compositions ...
