Extrusion | Encyclopedia

2018-5-8 · extrusion The emission of magma from a vent or fissure on to the Earth''s surface where it forms a lava flow. Gas is released quietly, rather than explosively, from the magma at the source vent and consequently there is little associated pyroclastic activity. Gas may also be vented from a different source, or extrusion may be of lava (magma) which has been degassed previously.
