| We suggest that primitive magmas ascending from the mantle are normally trapped in magma chamber complexes situated at or near the Moho. |
|
| When magma moves beneath a volcano, such as when the magma chamber fills prior to an eruption, there is swelling of the volcanic cone above. |
|
| The frequent but low-level activity of Vesuvius in recent centuries has relieved the build-up of pressure in the magma chamber. |
|
| When gas from the magma chamber has been exhausted, the lava erupts more quietly to form a broader and lower edifice, a shield volcano. |
|
| The typical image that this process invokes is that of a magma chamber with bits and pieces of the enclosing country rock or wall rock floating in the magma. |
|
| The injection of a mafic magma into a more silicic magma chamber is an important trigger mechanism in moderate-sized andesitic, dacitic and rhyolitic eruptions. |
|
| Named after an evil troll, Katla has a larger magma chamber than Eyjafjallajokul's, according to local scientist Páll Einarsson. |
|
| Unlike conventional magma eruptions there are no precursor earthquakes, or changes in the magma chamber, to provide early warning. |
|
| The lower gabbro layer has a stratified structure and evidently represents the floor or sides of the magma chamber. |
|
| In the last few years, the volcano grew more seismically active, began inflating in the magma chamber and showed increased geothermal activity. |
|
| The eruptions cause rapid evacuation of the magma chamber and collapse of the overlying volcano summit. |
|
| Layer of impermeable rock that transmits heat from the magma chamber to the aquifer. |
|
| Magmatic processes include inflation or deflation of the magma chamber and fractures filling with magma. |
|
| The lake is a shallow basin that slumped after volcanic activity emptied its magma chamber beneath. |
|
| The largest volcano in the world can spew 5 million tons of lava in one hour from a massive magma chamber. |
|
| How can a soda bottle be compared to a magma chamber of a volcano? |
|
| The copper containing dikes are derived from a larger magma chamber with a similar composition and copper content. |
|
| Aquamarine typically forms when magma, or melted rock, cools in an underground pocket called a magma chamber. |
|
| Leg 118 recovered 500 meters of gabbroic rocks that formed in a magma chamber beneath the very slow-spreading Southwest Indian Ridge. |
|
| A model explains how a magma chamber works. |
|
|
|
| They concluded that cracking associated with the recharge of the axial magma chamber was the key mechanism for localizing and maintaining black-smoker vent fields over long periods of time. |
|
| This work can also help to explain processes that occur within the Earth, such as subduction and magma chamber evolution. |
|
| This year, a gig inside the magma chamber of the Thrihnukagigur volcano. |
|
| The full magma chamber is equivalent in height to three versions of the Statue of Liberty stacked one on top of the other, with tunnels descending to a depth of 200 metres. |
|
| As new oceanic crust is formed, thick sequences of pillow lavas are erupted at the spreading center fed by dykes from the underlying magma chamber. |
|
| The drilling established that a dynamic magma chamber is present and is responsible for the mixing of geologic units and subsequent related mineralization. |
|
| The eruption of such a huge quantity of magma emptied the magma chamber beneath the volcano and led to the collapse of the overlying rocks to form the caldera. |
|
| Now, a post on Riot Games' site has confirmed that Magma Chamber will be released prior to the start of Season 4, whose start date has yet to be announced. |
