Distinguishing between barren and fertile batholiths in the same porphyry-Cu district using zircon trace element geochemistry
conference contribution
posted on 2023-05-23, 12:58 authored by Ahmed, AD, David CookeDavid Cooke, Agnew, P, Kobussen, A, Mills, S, Evan Orovan, Michael BakerMichael BakerZircon trace element chemistry, particularly when combined with U–Pb dating of zircon, can provide crucial information on the temporal, and chemical evolution of magmatic-hydrothermal systems. Sixteen samples representing six different igneous units were analysed for 33 elements using LA-ICPMS. Zircons from the mineralised Luhr Hill intrusion have smaller negative Eu/Eu* anomalies than zircons from the post-mineralisation Shamrock intrusion. Zircons from the Shamrock intrusion show a different trace element chemistry to zircons from either pre- or syn-mineralisation intrusions. Zircons from the Shamrock batholith contain elevated Ho, P, U, Yb and Er. Zircons from the Yerington batholith contain elevated Dy, Tb, Y, Lu, and Yb.
