Basics--Geologic Time - Commons - Wenatchee Valley College Some granites form (1) by magmatic processes — a crystallization of magma (melted silicate rock) — with the final form dependent upon crystal settling and the order of crystallization of minerals, (2) by melting of sedimentary rocks whose chemical composition is the same as that in granite, (3) by partial melting of rocks in which the first minerals to melt have the composition of granite; and finally, (4) by chemical replacement processes (Hyndman 1985; Clarke 1992; Collins 1988; Hunt and others 1992).
