If the water content of magma is high

WebGases break the rock, the magma exploits them and because of the lowering of the pressure it starts expanding into higher volume and really starts the process going. Higher pressure from rock, ice, ocean or a combination of all of them would serve to keep that gas from expanding. But also as widely accepted is the 3-5 km magma buoyancy equilibrium. WebFluxes like water, boron, phosphorus, fluorine etc. can strongly reduce melting point. E.g. dry haplogranite barely melts at 700 Celsius while some pegmatite melts with extreme water and volatiles content can obviously exist bellow 500 Celsius. Dry anorogenic granites or ryolites have much higher melting point then some wet S-type granites.

Web6 mei 2024 · If the magma is felsic, and therefore too viscous for gases to escape easily, or if it has a particularly high gas content, it is likely to be under high pressure. Viscous magma doesn’t flow easily, so even if there is a conduit for it to move towards surface, it may not flow out.

Web22 jul. 2024 · What effects do the water and silica content of magma have on volcanic eruptions? The higher the temperature of the magma the lower the viscosity. The higher the amount of silica (which is present in all magmas) the higher the viscosity due to the ability of the silica to form chains (polymers) that link together and hinder the movement … Magma exists in three main forms that vary in composition. When magma crystallizes within the crust, it forms an extrusive igneous rock. Dependent on the composition of the magma, it may form either rhyolite, andesite, or basalt. Volatiles, particularly water and carbon dioxide, significantly impact the behavior of each form of magma differently. Magma with a high concentration of volatil…
