At 10 kb, garnet quartz, biotite, sillimanite, and plagioclase constitute the residuum coexisting with granitic liquid.Compositions of residual phases and their Mg-Fe partition relationships compare closely with phases from cordierite- and garnet-bearing granitic rocks in eastern Australia and strongly support geochemical arguments that this particular granitic suite is derived by partial melting of pelitic sediments. Thus, the cordierite-bearing granitic rocks were probably derived by partial melting of pelite at >25-km depth, whereas the garnet-bearing granites were derived at ≿25-km depth.
