AB - Apatite is well suited to the study of porphyry systems. It occurs in both the magmatic and hydrothermal domains and the large range in possible trace element substitutions can reveal crystallisation conditions that reflect key events during porphyry formation. This project aims to use the trace element chemistry of apatite as a probe of porphyry development. A global study of apatite composition will aim to identify fingerprints which may be indicative of a fertile porphyry environment. Initial results from the Chuquicamata Cu-Mo porphyry, Chile reveal limited compositional differences in major and trace element compositions (Ca, P, Cl, Na, Mn, S, Se, Fe, Mg, Al, Si, La, Ce, Nd) between apatites of different habits that are interpreted to be magmatic in origin. However, vein-hosted and hydrothermally-altered apatite are compositionally distinct, probably controlled by strong fractionation of elements during separation of magmatic-hydrothermal fluids. This suggests potential for the future study of potassic alteration in porphyry systems using apatite.
