Porosity and permeability in volcanic rocks: A case study on the Serie Tobífera, South Patagonia, Argentina
(Elsevier Science, 2004-04)
The Middle to Late Jurassic Serie Tobífera belongs to the Chon-Aike Province and extends all over Patagonia and the Antarctic Peninsula. It consists largely of ignimbrites, epiclastics and rhyolitic lavas and was considered ...
Possible structural control on the 2011 eruption of Puyehue-Cordon Caulle Volcanic Complex (southern Chile) determined by InSAR, GPS and seismicity
(2017)
The Puyehue-Cordon Caulle Volcanic Complex (PCCVC) is one of the best examples of tectonic control on volcanism at the Southern Volcanic Zone of the Andes (southern Chile). The PCCVC comprises several volcanic centres that ...
Combined U-Pb and Lu-Hf isotope study from the Las Lozas volcanics, northwestern Argentina: Evidence of juvenile Cryogenian-derived, lower Pennsylvanian volcanism in western Gondwana
(Pergamon-Elsevier Science Ltd, 2015-04)
Las Lozas volcanic succession, cropping out in the southwestern Puna, Catamarca province, Argentina, consists of an intracontinental volcanic sequence of Carboniferous age. The lavic members are predominantly rhyolites, ...

Quantitative spatial distribution analysis of mafic monogenic volcanism in the southern Puna, Argentina: Implications for magma production rates and structural control during its ascent
(Pergamon-Elsevier Science Ltd, 2020-12)
Establishing the factors that control the pathways of magma ascent is an important issue in the study of monogenic mafic volcanism since it provides information about the relationship between the source of the ascending ...
Crustal collapse in the Andean backarc since 2 Ma: Tromen volcanic plateau, Southern Central Andes (36°40′-37°30′S)
(Elsevier Science, 2008-11)
Analysis of seismic lines and gravity data shows the existence of Quaternary extensional depocenters beneath thick covers of < 1 Ma-old volcanic rocks in the Tromen volcanic plateau backarc region (36°40′-37°30′S). Dating ...
Volcanic alert system by lightning detection using the WWLLN - ash cloud monitor
(Pergamon-Elsevier Science Ltd, 2021-06)
Electrical discharges are observed in many volcanic eruptions and they have often been used as indicators of such eruptions. Volcanic lightning is remarkably similar to those produced during thunderstorms and is called ...
