This is because most magma from which igneous rock solidifies is produced by partial melting of a mixture of different minerals. At first the mixed melt slowly cools deep in the crust. The magma begins crystallizing the highest melting point minerals closest to the overall composition first, in a process called fractional crystallization. This forms phenocrysts, which usually have plenty of room for growth, and form l…
