In Iceland the volcanic vents often are long fissures parallel to the rift zone where lithospheric plates are diverging. |
Magmas erupted in continental volcanic arcs typically contain components from many sources in the crust, lithospheric mantle and asthenosphere. |
It appears that basic magmas across the Gardar Province were derived from a heterogeneous, enriched lithospheric mantle reservoir. |
This suggests that the peralkaline volcanic magma was derived from a lithospheric mantle source that had not been previously depleted in incompatible elements. |
Rate of lithospheric thinning and precise timescale of the eruption of lavas in the British Tertiary Volcanic Province. |
Most of the 600 or so active volcanoes of the world are located at the margins of the big lithospheric plates which make up the Earth's crust. |
