WebAs magma erupted at the surface is difficult to sample, the solid rocks that form after cooling provide us with the most information on the chemistry of magmas. Most contain silicate minerals (in which Si, Al, Mg, Fe, Ca, Na and K combine with oxygen) and some minor oxide minerals. These rocks are made up of: WebVolcanic eruptions are inherently physical processes given that they are the emission of gas, magma, and rock from within the Earth. Yet many aspects of eruptions are actually controlled by magma chemistry. Magma consists of liquid rock that usually contains suspended solid crystals. As magma approaches the surface and the overburden pressure drops, dissolved gases bubble out of the liquid, so that magma near the surface consists of materials in solid, liquid, and gas phases. Most magma is rich in silica. Rare nonsilicate magma can form by local melting of nonsilicate mineral deposits or by separation of a magma into separate immiscible silicate and nonsilicate liq… motown wall clock

"WebWhen magma has high levels of silica like felsic, it means that it is highly viscous and has a lower pyroclastic flow; if magma has low levels of silica, it has low viscosity like mafic, and therefore it has low viscosity, by implication it will have a high pyroclastic flow.
