Distinguishing magmatic zircon from hydrothermal zircon: A case study from the Gidginbung high-sulphidation Au-Ag-(Cu) deposit, SE Australia
Zircons within the mineralized, silica-pyrite zone of the Gidginbung (Temora) high-sulphidation Au-Ag-(Cu) deposit in the Lachlan Orogen, Australia have been analyzed by both ion microprobe and laser ablation inductively coupled plasma mass spectrometry for titanium and rare earth element (REE) concentrations, as well as their oxygen and hafnium isotopic compositions. These zircons were previously interpreted to be hydrothermal in origin, but the new data are indicative of a magmatic origin....[Show more]
