Magma degassing during subglacial eruptions and its use to reconstruct palaeo-ice thicknesses
نویسنده
چکیده
15 16 The degassing of magmatic volatiles during eruptions beneath ice sheets and glaciers, 17 as recorded by the dissolved volatile content quenched in volcanic rocks, could 18 provide powerful new constraints on former ice thicknesses in volcanic areas. As 19 volcanic rocks are readily dateable using radiometric methods, subglacial volcanoes 20 may therefore provide crucial information on the timing of palaeo-environmental 21 fluctuations in the Quaternary. Volatile degassing is also likely to control the 22 mechanisms of subglacial eruptions and their associated hazards. 23

Models of ice melting and edifice growth at the onset of subglacial basaltic eruptions
[1] Models of the early stages of basaltic eruptions beneath temperate glaciers are presented that consider the evolving sizes of volcanic edifices emplaced within subglacial cavities. The cavity size reflects the competing effects of enlargement by melting and closure by downward ductile deformation of the ice roof, which occurs when the cavity pressure is less than glaciostatic due to meltwat...
متن کاملHeat transfer in volcano–ice interactions on Earth
The very high temperature contrast between magma/lava and water ice commonly leads to the assumption that significant melting will take place immediately upon magma/lava ice contact, yet observations of active flows show little evidence of voluminous melting upon contact. We use analytical thermal models to reassess the efficiency with which heat can be transferred from magma to ice in three si...
متن کاملJökulhlaups in Iceland : sources, release and drainage
Jökulhlaups in Iceland may originate from marginal or subglacial sources of water melted by atmospheric processes, permanent geothermal heat or volcanic eruptions. Glacier-volcano interactions produce meltwater that either drains toward the glacier margin or accumulates in subglacial lakes. Accumulated meltwater drains periodically in jökulhlaups from the subglacial lakes and occasionally durin...
متن کاملCauldron subsidence and subglacial floods
Ice cauldrons are depressions which form at the surface of ice sheets when an underlying subglacial lake empties. Notable examples of such cauldrons occur on the surface of the Vatnajökull ice cap in Iceland, and in particular are formed when subglacial volcanic eruptions occur. More generally, cauldrons will form when a subglacial lake empties during a jökulhlaup. The rate of subsidence of the...
متن کاملDegassing during quiescence as a trigger of magma ascent and volcanic eruptions
Understanding the mechanisms that control the start-up of volcanic unrest is crucial to improve the forecasting of eruptions at active volcanoes. Among the most active volcanoes in the world are the so-called persistently degassing ones (e.g., Etna, Italy; Merapi, Indonesia), which emit massive amounts of gas during quiescence (several kilotonnes per day) and erupt every few months or years. Th...
