  2. Magma chamber - Wikipedia

    en.wikipedia.org/wiki/Magma_chamber

    A magma chamber is a large pool of liquid rock beneath the surface of the Earth. The molten rock, or magma, in such a chamber is less dense than the surrounding country rock, which produces buoyant forces on the magma that tend to drive it upwards. [1] If the magma finds a path to the surface, then the result will be a volcanic eruption ...

  3. Surface features of Venus - Wikipedia

    en.wikipedia.org/wiki/Surface_features_of_Venus

    The trapping of a magma chamber allows long-term eruption, and results in magma flows that may create large volcanic domes and flow deposits. The extrusion of magma to the surface is often linked to rifting or extensional tectonics in the region, and the shape of the dome or magma flow field is determined by the chemistry and viscosity of the ...

  4. Yellowstone Caldera - Wikipedia

    en.wikipedia.org/wiki/Yellowstone_Caldera

    The Yellowstone Caldera, sometimes referred to as the Yellowstone Supervolcano, is a volcanic caldera and supervolcano in Yellowstone National Park in the Western United States. The caldera and most of the park are located in the northwest corner of the state of Wyoming. The caldera measures 43 by 28 miles (70 by 45 kilometers), and postcaldera ...

  5. Magma - Wikipedia

    en.wikipedia.org/wiki/Magma

    Magma that cools slowly within a magma chamber usually ends up forming bodies of plutonic rocks such as gabbro, diorite and granite, depending upon the composition of the magma. Alternatively, if the magma is erupted it forms volcanic rocks such as basalt , andesite and rhyolite (the extrusive equivalents of gabbro, diorite and granite ...

  6. Cave of the Crystals - Wikipedia

    en.wikipedia.org/wiki/Cave_of_the_Crystals

    Note person for scale. Cave of the Crystals or Giant Crystal Cave (Spanish: Cueva de los cristales) is a cave connected to the Naica Mine at a depth of 300 metres (980 ft), in Naica, Chihuahua, Mexico. It takes the form of a chamber within the limestone host rock of the mine, and is about 109 metres (358 ft) long with a volume of 5,000 to 6,000 ...

  7. Volcanic and igneous plumbing systems - Wikipedia

    en.wikipedia.org/wiki/Volcanic_and_igneous...

    Volcanic and igneous plumbing systems (VIPS) consist of interconnected magma channels and chambers through which magma flows and is stored within Earth's crust. [ 1] Volcanic plumbing systems can be found in all active tectonic settings, such as mid-oceanic ridges, subduction zones, and mantle plumes, when magmas generated in continental ...

  8. Chile Ridge - Wikipedia

    en.wikipedia.org/wiki/Chile_Ridge

    CTJ stands for Chile Tripple Junction. A) The ridge is located at the edge of the Chile Trench. the Magma chambers developed and cause the upwelling of the ophiolite onto the surface of the spreading ridge. Cabo Raper pluton is also shown in the diagram. B) The old magma chamber is pushed away by the new magma chamber.

  9. Campanian Ignimbrite eruption - Wikipedia

    en.wikipedia.org/wiki/Campanian_Ignimbrite_eruption

    The structure's magma chamber remains active as there apparently are solfataras, hot springs, gas emissions and frequent episodes of large-scale up- and downlift ground deformation do occur. [18] [19] In 2008 it was discovered that the Phlegraean Fields and Mount Vesuvius have a common magma chamber at a depth of 10 km (6.2 mi). [20]
