Magma with high viscosity

WebMagma with a higher silica content is more viscous, which means it is thicker and less fluid. This is because silica tetrahedra can link together to form long chains that impede the flow of magma. Other factors, such as temperature, pressure, and the amount of dissolved gas, can also influence magma viscosity. 36. WebThe ability of a fluid to flow is its viscosity. The viscosity of a fluid is said to be low if it moves quickly. On the other hand, if a fluid moves slowly, its viscosity is said to be …

WebWe found, for bubble-induced shearing to occur, we need small strain rates (0.005 s-1), high viscosities (107-108 Pa.s) and intermediate temperatures (700 – 800 °C). We calculated that it took respectively 84 days and 80 days to completely cool the lava at Sancy and Royat to such temperatures. WebThey include rhyolite and dacite magmas. With such a high silica content, these magmas are extremely viscous, ranging from 10 8 cP (10 5 Pa⋅s) for hot rhyolite magma at 1,200 °C (2,190 °F) to 10 11 cP (10 8 Pa⋅s) for …
