    • Prior to any volcanic eruption, magma wells up through the earth's crust via any weaknesses in the rock structure.
    • Melts form at the highest temperatures and lowest pressures resulting in large volumes of tholeiitic magma that form shield volcanoes such as Mauna Loa.
    • Normally magma would fill the crack and the adjacent plates would inch away by just that amount.
    • An aircraft will soon fly over the lava dome to test for the presence of carbon dioxide and sulfur dioxide, signs that magma might be building up.
    • Magmas concentrate metals, and magma fluids traveling into the surrounding wall rock plant the seeds for mineral growth.
    • Scientists believe that diamonds ascend to the earth's surface in rare molten rock, or magma that originates at great depths.
    • Vulcanites, such as basalt and fire opal, will be formed within erupted magma where cooling is rapid and only tiny crystals have the chance to form.
    • From beneath the dome, the magma could combine with pressurized gases and steam to trigger an eruption, Pierson said.
    • Dolerite is basaltic magma that solidifies rapidly in sills and dikes near the surface.
    • Injections of new batches of mafic magma have been important for triggering dacitic eruptions.
    • Massive sulfide deposits may also form in other settings where water circulates in rocks near cooling magma.
    • Crystals of the mineral were then carried in suspension by the upward-moving magma and forced toward the center of the flowing slurry.
    • Until the rocks crystallized, uranium atoms could move freely through the molten magma from which they formed, and decayed uranium could be replenished.
    • The continuing uplift of the caldera rim can be explained by the restricted size of the magma's exit route.
    • Two years ago the magma was close enough to the crown of the volcano to be seen clearly from the air.
    • As old oceanic crust was consumed in the trenches, new magma rose and erupted along the spreading ridges to form new crust.
    • Igneous rocks are those that have formed from molten magma.
    • This magma is rich in carbon dioxide gas, which produces explosive eruptions.
    • In other words, the magma is squeezed upwards as thin sheets through long, narrow fractures.
    • What they do know is that a ‘slow rise’ of magma is driving lava to the surface, which has created a new lava dome in the mountain's crater.
