Geochemical characteristics of central Chile (33 °-34 °S) granitoids
Seventeen granitoid samples from batholiths in central Chile (33 °-34 ° S) have been analyzed for trace element content. The samples range in age from Paleozoic to Tertiary, and in rock type from quartz diorite to granite. ...
Andesites and high-alumina basalts from the central-south Chile high Andes: Geochemical evidence bearing on their petrogenesis
High-alumina basalts from seven High-Andean stratovolcanoes (37 °30′S to 41 °S) have major and trace element (including rare earth elements, REE) that are consistent with derivation by partial melting (typically 10-15%) ...
Abanico East Formation: petrology and geochemistry of volcanic rocks behind the Cenozoic arc front in the Andean Cordillera, central Chile (33°50'S)

Electromagnetic instabilities in a gyrotropic and nongyrotropic hybrid solar-wind-like plasma
(Blackwell Publishing Ltd, 1998)
We study the stability of electromagnetic waves for nongyrotropic velocity distribution functions in a solar-wind-like plasma. The dispersion relation is solved numerically in closed form. On the basis of recently reported ...

The impact of a buried high-velocity layer in the seismic site amplification of the city of Llolleo, Chile
(Seismological Society of America, 2018)
We studied the influence of a buried high-velocity layer (HVL) on the surface ground amplification of the city of Llolleo, Chile, where large peak ground accelerations were observed during the 1985 Mw 8.0 Valparaiso and ...
Transient shallow reservoirs beneath small eruptive centres: Constraints from Mg-Fe interdiffusion in olivine
Small eruptive centres commonly have more primitive lavas than those associated with stratovolcanoes, an observation that has been taken to indicate a short magma residence in the crust relative to those reservoirs below ...

Ion acoustic damping effects on parametric decays of Alfvén waves
(Blackwell Publishing Ltd, 2000)
It is well known that in plasmas with β = (νs/νA)2 < 1 (νs is the ion acoustic velocity and νA is the Alfvén velocity), Alfvén waves propagating along an external magnetic field can have three kinds of parametric ...
