Web4 aug. 2024 · It's not as simple as, say, dropping a bit of melting candy into cold water and watching it cool into a lump. When lava hits water, it's so hot that two things happen. First, the water boils away into nothingness, and the salt that's left behind is super-heated. Then yes, the lava cools, but it turns into something called volcanic glass. Solidified lava on the Earth's crust is predominantly silicate minerals: mostly feldspars, feldspathoids, olivine, pyroxenes, amphiboles, micas and quartz. Rare nonsilicate lavas can be formed by local melting of nonsilicate mineral deposits or by separation of a magma into immiscible silicate and nonsilicate liquid phases.
