WebDehydration melting of metasupracrustal rocks at mid- to deep-crustal levels can generate water undersaturated granitic melt. In this study, we evaluate the potential of ∼1.89–1.88 Ga metasupracrustal rocks of the Precambrian of southern Finland as source rocks for the 1.86–1.79 Ga late-orogenic leucogranites in the region, using the Rhyolite-MELTS … Web12 dec. 2016 · Basaltic lava is formed from magma that is low in silica. This makes for a more fluid magma that allows gas bubbles to expand on the way up to the surface, preventing sudden explosive activity. Rhyolitic and Andesitic lavas are formed from silica-rich magma that is very viscous.
