"Webb15 aug. 2024 · Rhyolite flows form a cooled surface crust that buckles into ogives as the lava flow front slows ( Fink, 1980a; Castro and Cashman, 1999 ). The crust insulates the lava flow core, potentially maintaining core mobility long after effusion ceases ( Manley, 1992; Farquharson et al., 2015 ). " - Rhyolite cooling

WebbNote that a granite is the coarse grained equivalent of a rhyolite. That is, if the rate of cooling is very slow a granite will form. The same melt, cooled rapidly, will form a rhyolite. The relationship between temperature and mineralogy allows another over-simplification that relates igneous rock type to plate tectionic setting:
