WebSiliceous Lava Flows - High viscosity andesitic and rhyolitic lava flows, because they can’t flow very easily, form thick stubby flows that don’t move far from the vent. Lava Domes or Volcanic Domes - result from the extrusion of highly viscous, gas poor andesitic and rhyolitic lava. Since the viscosity is so high, the lava does not flow ... WebThis is because the high silica content increases the amount of chemical bonding between the lava's constituent particles, making it more difficult for them to slide past each other. As a result of its high viscosity, felsic lava tends to flow slowly and can form steep-sided volcanoes due to the buildup of lava around the vent. Examples of ...
