How does silica affect the viscosity of magma

WebHow does silica content affect viscosity? A magma’s silica content will not only control the rock type that forms, it also controls the relative viscosity of the magma. Differences in a magma’s viscosity will determine the shape a volcano takes. High-silica (basalt) magma has a much lower viscosity. It flows much easier and over longer ... WebSep 4, 2024 · Magmas that have a high silica content will therefore exhibit greater degrees of polymerization, and have higher viscosities, than those with low-silica contents. The amount of dissolved gases in the magma can also affect it’s viscosity, but in a more ambiguous way than temperature and silica content. Click to see full answer.

WebSilica (SiO2) content has the greatest impact on magma viscosity. Most igneous rocks are made predominately of silica with concentrations ranging from about 45 to 78% by weight. Specifically, silica is arranged in tetrahedrons (Si04 complexes). Silica tetrahedrons can share oxygen atoms to form chains or networks in a melt.

WebJan 1, 1999 · The net effect of liquid magma composition and water content on the behavior of explosive volcanic eruptions was investigated by the use of numerical simulation. ... It is well-known paper we simply focus on the behavior of 6 simulations that a silica-rich magma has a viscosity greater than a identified by the capital letters A-F and by the ... WebIn magmas, viscosity (14) is created by the number of bonds between SiO2 tetrahedrons (11) (O-O bond). The higher the number of bonds, the higher the viscosity! One way to change the viscosity of a magma is too add water. Water has the effect of depolymerizing (6) magmas. That means that adding water breaks oxygen bonds in magmatic network.
