... Mantle Plumes – are thin pencil-like streams of lava that rise from great depths allowing hot basaltic magma to rise and erupt far from plate boundaries. Basaltic Magmas come from : 1) upper mantle beneath mid-ocean ridges 2) mantle plumes Magmatic differentiation – a uniform parent magma develops a ...

Basalt
Basalt (pronounced /bəˈsɔːlt/, /ˈbæsɒlt/, /ˈbæsɔːlt/, or /ˈbeɪsɔːlt/)is a common extrusive igneous (volcanic) rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of a planet or moon. Flood basalt describes the formation in a series of lava basalt flows.
