Volcanism and the atmosphere: the potential role of the atmosphere in unlocking the reactivity of volcanic emissions.
Recent measurements of reactive trace gas species in volcanic plumes have offered intriguing hints at the chemistry occurring in the hot environment at volcanic vents. This has led to the recognition that volcanic vents should be regarded not only as passive sources of volcanic gases to the atmosphere, but also as 'reaction vessels' that unlock otherwise inert volcanic and atmospheric gas speci...
متن کاملExplosive Volcanism on Atmosphere-less Bodies - a Comparison of the Moon, Mercury and Io
Introduction: There is abundant observational evidence of explosive volcanism on all three of the large airless silicate-dominated bodies, the Moon [1], Mercury [2] and Io [3]. The lack of atmospheres makes analysis of explosive activity relatively simple. We combine the results of earlier analyses of explosive volcanism to draw inferences about the geologic circumstances of explosive activity ...
متن کاملVolcanism and associated hazards: the Andean perspective
Andean volcanism occurs within the Andean Volcanic Arc (AVA), which is the product of subduction of the Nazca Plate and Antarctica Plates beneath the South America Plate. The AVA is Earth’s longest but discontinuous continental-margin volcanic arc, which consists of four distinct segments: Northern Volcanic Zone, Central Volcanic Zone, Southern Volcanic Zone, and Austral Volcanic Zone. These se...
متن کاملVolcanism and Tectonics on Venus
We review recent developments in the study of volcanism and tectonics on Venus. Venus’s crust is basaltic, dry, and probably about 30 km thick. The mantle convects, giving rise to plumes, and has a similar composition and mean temperature (∼1300◦C), but a higher viscosity (∼1020 Pa s), than that of the Earth. Inferred melt generation rates constrain the lithospheric thickness to between 80 and ...
متن کاملMud volcanism: Processes and implications
Mud volcanoes can be large and long lived geological structures that morphologically resemble magmatic volcanoes. Because of their capricious behaviour and their spectacular morphology and landscapes, mud volcanoes have attracted attention since antiquity. More recently, mud volcanoes have become the focus of extensive studies for natural science research, including geologists and biologists. M...
