How do mineral crystals form in a magma
WebAs magma rises up through the crust, either by volcanic eruption or by more gradual processes, it cools and minerals crystallize. When cooling is rapid and many crystals form at once, only small mineral grains will form before the rock becomes solid. The resulting rock will be fine-grained (i.e., crystals less than 1 mm). WebMineral crystals that form when magma cools slowly are larger than crystals that form when lava cools rapidly. Minerals form when rocks are heated enough that atoms of different …
