From: A rapid change in magma plumbing taps porphyry copper deposit-forming magmas
Depth of different magma sources: CIPW normative mineralogy (method of90) from whole-rock XRF data for aplite dykes and LHG plotted on the H2O-saturated haplogranitic melt minima plot of78 (after77). Samples overprinted by intensive Na–Ca alteration are not plotted. Porphyry dykes plotted in Fig. S18.
