Gas discharges from four remote volcanoes in northern Chile (Putana, Olca, Irruputuncu and Alitar): a geochemical survey
Fluid geochemistry Subduction zone Volcanic risk Geochemical data Volcano monitoring
2015/8/27
We analyzed gas samples collected from fumaroles and bubbling pools at Irruputuncu, Putana, Olca and Alitar volcanoes located in the central Andes volcanic zone (northern Chile). The Irruputuncu and P...
Petrogenesis of the ridge subduction-related granitoids from the Taitao Peninsula, Chile Triple Junction Area
granite ridge-subduction slab-melting Taitao adakite TTG
2017/4/11
Geochemical compositions are reported for Late Miocene to Pliocene granitoids from the Taitao Peninsula near the
Chile ridge subduction zone. Major element compositions of Taitao granitoids show a re...

2017/4/11
The ophiolitic remnants of the Upper Mesozoic Rocas Verdes basin in southernmost South America were studied from
the perspectives of petrography, chemistry of minerals, bulk-rock geochemistry, and U–...
Petit-spot lava fields off the central Chile trench induced by plate flexure
hpetit-spot Chile trench alkali-basalt Nazca plate Juan Fernández hotspot
2017/4/11
In 2009, petit-spot submarine volcanoes were discovered off the oceanward slope of the central Chile trench, offshore
from Valparaiso, Chile, at around 33°S. Ar–Ar dating of mugearite and alkali-basa...
Supergene Origin of the Lastarria Kaolin Deposit, South-Central Chile, and Paleoclimatic Implications
