| 释义 |
GeneralThree forms of glaciovolcanism are known. Subglacial eruptions occur when a volcano erupts under ice. Such activity can produce landforms such as tuyas and subglacial mounds. Ice-marginal volcanism takes place when material from a subaerial eruption makes lateral contact with ice. Ice-marginal lava flows are a product of this phenomenon. Supraglacial eruptions deposit ejecta onto the surface of an ice sheet.[2] ExamplesIsostatic rebound in response to glacier retreat (unloading), increase in local salinity (i.e., δ18Osw), have been attributed to increased volcanic activity at the onset of Bølling–Allerød, are associated with the interval of intense volcanic activity, hinting at a interaction between climate and volcanism - enhanced short-term melting of glaciers, possibly via albedo changes from particle fallout on glacier surfaces.[3]See also
