The composition and origin of any magma that differentiates into granite go away sure petrological proof as to what the granite’s parental rock was.
The ultimate texture and composition of a granite are usually distinctive as to its parental rock.
For occasion, a granite that’s derived from partial melting of metasedimentary rocks might have extra alkali feldspar, whereas a granite derived from partial melting of metaigneous rocks could also be richer in plagioclase.
It is on this foundation that the fashionable “alphabet” classification schemes are based mostly. The letter-based chappell & white classification system was proposed initially to divide granites into i-type (igneous supply) granite and s-type (sedimentary sources).
 each sorts are produced by partial melting of crustal rocks, both metaigneous rocks or metasedimentary rocks.
