fu·ma·role

F0360300 (fyo͞o′mə-rōl′)n. A hole in a volcanic area from which hot smoke and gases escape.

[Italian fumarola, from Late Latin fūmāriolum, smoke hole, diminutive of Latin fūmārium, smoke chamber, from fūmus, smoke.]

fu′ma·rol′ic (-rŏl′ĭk) adj.

fumarole

(ˈfjuːməˌrəʊl) n (Geological Science) a vent in or near a volcano from which hot gases, esp steam, are emitted[C19: from French fumerolle, from Late Latin fūmāriolum smoke hole, from Latin fūmus smoke] fumarolic adj

fu•ma•role

(ˈfyu məˌroʊl)

n. a hole in or near a volcano from which vapor rises. [1805–15; < French fumerolle < Late Latin fūmāriōlum, diminutive of Latin fūmārium smoke chamber] fu`ma•rol′ic (-ˈrɒl ɪk) adj.

fu·ma·role

(fyo͞o′mə-rōl′) A hole in the surface of the Earth from which hot smoke and gases escape. Fumaroles are found on or near volcanoes.

fumarole

[′fyü·mə‚rōl] (geology) A hole, usually found in volcanic areas, from which vapors or gases escape.

Fumarole

a small vent or fissure from which hot gases issue. The gases may include H₂O, HCl, HF, SO₂, CO₂, CO, H₂S, and H₂. If the gases are emitted from magma, the vent is called a primary fumarole; if they are emitted from lava flows or pyroclastics that have not yet solidified, the vent is referred to as a secondary, or rootless, fumarole.

Fumaroles may be located in the crater, on the slopes, or at the foot of a volcano. The gases are emitted under pressure, frequently resulting in a loud hissing or roaring. As the temperature decreases, the water vapor undergoes a transformation to the liquid state. Depending on thermodynamic conditions, certain gases emitted along with the water vapor are dissolved in the liquid water, as are various gases and substances that are produced as a result of reactions with the wall rock and that are encountered on the way to the earth’s surface. In this way, hydrothermal solutions form hot springs in the vicinity of active volcanoes.

The deposition of sublimates of halides, sulfates, native sulfur, and other minerals is associated with fumaroles.
