text: In contrast, magma that is rich in gas and silica gives rise to violent explosions: the thick, tarlike magma may plug up the volcanic vent, blocking the upward movement of the magma until built-up pressure blows away the overlying rock.
text: There are relatively few minerals that are important in the formation of common igneous rocks, because the magma from which the minerals crystallize is rich in only certain elements: silicon, oxygen, aluminium, sodium, potassium, calcium, iron, and magnesium.
text: If the magma is rich in silica, the caldera is often filled in with ignimbrite, tuff, rhyolite, and other igneous rocks.
text: In magmas that are rich in aluminosilicate and alkali components, therefore, feldspars separate out earlier than dark-colored minerals (in granites).
text: Their eruptions are typically explosive and effusive; the magma is generally rich in volatiles because the magma rises as water trapped both in hydrated minerals and porous basalt rock of the upper oceanic crust is released into mantle rock of the asthenosphere above the sinking oceanic slab.

text: When magma is rich in gas, it can produce explosive eruptions.
