WebHigh viscosity lavas flow slowly and typically cover small areas. In contrast, low viscosity magmas flow more rapidly and form lava flows that cover thousands of square kilometers. Low viscosity magmas allow gases to escape easily whereas g as pressures can build up in high viscosity magmas – resulting in violent eruptions WebThere are two types of lava flows. 1. Mafic or basaltic lava flows: Basaltic or mafic lava means lower viscosity which means it is more likely to flow readily. Basalt melts at an extremely high temperature because it contains more mafic minerals like olivine and pyroxene with extremely high melting temperatures. small tabletop flower arrangements
