Full description

Ten samples from a range of magmatic lithologies and spatial locations were selected for oxygen isotope analysis (Table 1). Zircon grains were separated from hand-sized samples of rock using a combination of crushing, hand panning and magnetic separation and hand picking to obtain a clean separate. Zircon grains were mounted in epoxy resin and polished to half grain thickness, before being photographed in transmitted and reflected light on an optical microscope. Zircon grains were then imaged using a Gatan Cathodoluminescence (CL) detector attached to a FEI Quanta 600 Scanning Electron Microscope (SEM) at Adelaide Microscopy, University of Adelaide, Australia. Oxygen isotope analysis was done prior to LA-ICPMS analysis to avoid potential issues caused by laser pits. Spot locations were selected using CL and transmitted light images. All oxygen isotope spot locations are provided in the attached CL mosaics for each sample.

Oxygen isotope ratios (18O/16O) were determined using a Cameca IMS 1280 housed at the Centre for Microscopy Characterisation and Analysis at the University of Western Australia.

The dataset contains:

-    Two folders with CL images of zircons from each sample analysed for oxygen isotopes (11 samples in total). Oxygen isotope analyses are shown as red dots. These images also show spot locations chosen for determination of age, trace element composition and Hf isotope values via LAICPMS U-Pb+ trace elements and LASS-ICPMS U-Pb + Hf analysis.
-    A document containing detailed methodology
-    Two spreadsheets containing corrected oxygen isotope data (18O/16O) and data normalised to δ18O (quoted with respect to Vienna Standard Mean Ocean Water or VSMOW). The number at the end of each analysis name corresponds to the spot number on the CL images. This spreadsheet also contains data for each of the zircon standards analysed in the runs.

Notes

Purpose
Oxygen isotope data were collected from selected igneous rocks to better resolve the contributions of mantle and supracrustal melting to magmatism.
