Illustration of the crystal growth process that leads to melt inclusion entrapment

Illustration of the crystal growth process that leads to melt inclusion entrapment. (a) A crystal (gray area) nucleates and grows. (b) As the magma cools, the crystal corners will grow more efficiently than crystal edges. (c) This growth process will lead to the entrapment of surrounding melt (orange area).
