1. Concentracion mineral en praderas y bovinos expuestos a la erupcion del complejo volcanico lonquimay.
El Volcan Lonquimay (VL) localizado en los Andes Chilenos, entro en erupcion en diciembre de 1988, manteniendo-se activo por 13 meses. La lava, piroclastos y cenizas puede afectar la composicion mineral del pasto en el area de influencia de la erupcion con consecuentes danos sobre la poblacion animal a pastoreo. Con el objeto de establecer la concentracion f

2. Petrogêneses do complexo vulcânico Yate (42, 30ºS), Andes do Sul, Chile / Petrogenesis of the Yate Volcanic Complex (42, 30ºS), Andes Southern, Chile
The Yate Volcanic Complex (CVY) is located in the Southern Volcanic Zone of the Chilean Andes, at 42°30S, comprising the Yate, Gualaihué and Hornopirén volcanoes. The Yate volcano is a major compound type in which effusive activity occurred since Upper Pleistocene (c. 122 ka) until Holocene. Hornopirén and Gualaihué are minor, and represent strombilian-

3. Extinction and recolonization of local populations on a growing shield volcano.
Volcanic action has resulted in the burial of the surfaces of Mauna Loa and Kilauea, Hawaii, by new lava flows at rates as high as 90% per 1000 years. Local populations of organisms on such volcanoes are continually being exterminated; survival of the species requires colonization of younger flows. Certain populations of the endemic Hawaiian species Drosophi

4. Bipolar correlation of volcanism with millennial climate change
Analyzing data from our optical dust logger, we find that volcanic ash layers from the Siple Dome (Antarctica) borehole are simultaneous (with >99% rejection of the null hypothesis) with the onset of millennium-timescale cooling recorded at Greenland Ice Sheet Project 2 (GISP2; Greenland). These data are the best evidence yet for a causal connection between
