The magmatic feeding system of El Reventador volcano (Sub-Andean zone, Ecuador) constrained by texture, mineralogy and thermobarometry of the 2002 erupted …
After a 26 years long quiescence El Reventador, an active volcano of the rear-arc zone of
Ecuador, entered a new eruptive cycle which lasted from 3 November to mid December
2002. The initial sub-Plinian activity (VEI 4 with andesite pyroclastic falls and flows) shifted
on 6 and 21 November to an effusive stage characterized by the emission of two lava flows
(andesite to low-silica andesite Lava-1 and basaltic andesite Lava-2) containing abundant
gabbro cumulates. The erupted products are medium to high-K calc-alkaline and were …
