Plate Tectonics Magma formation Lava to erupt
Constructive
Midocean ridge Decompression and partial Mafic magma erupts to
melting of the form pillow basalts.
asthenosphere produces Basaltic Lava
mafic magma.
Destructive
Mafic to intermediate Eruptions range from mafic
magma, by partial melting to intermediate; often early
Oceanic Oceanic of waterrich ocean crust eruptions are mafic
becoming more
intermediate as the island
arcs grow.
Mafic to intermediate BUT predominantly
magma, by partial melting intimidate silicic eruptions
Oceanic Continental of waterrich ocean crust due to fractional
crystallisation and
assimilation of the
continental crust.
Silicic magmas forms as None, really, solidifies
Continental Continental wet silicic material is before reaching the surface.
compressed due to crustal If Yellowstone erupts we're
thickening screwed
Hot Spot
Partial melting in the Mafic magmas erupted
Under Oceanic crust asthenosphere produces
mafic magmas Basaltic lava
Partial melting in the Mafic magmas erupted
Under Continental crust asthenosphere produces
mafic magmas Basaltic lava
