Abstract:

This spreadsheet contains 21 oxygen isotope measurements for hematite and mixed hematite/goethite samples from the supergene profiles of the Spence and Cerro Colorado porphyry copper deposits in the Central Andes. Columns are also included which contain calculated isotopic values for weathering fluids which were present at the time of iron oxide formation. These data are presented and discussed in the G-cubed paper 'A rusty record of weathering and groundwater movement in the hyperarid Central Andes' (Shaw et al., 2021). Weathering fluid isotopic values are calculated using the published fractionation factors of Clayton & Epstein (1961), Yapp (1990) and Bao & Koch (1999). The authors have the most confidence in the fluid values obtained using the fractionation factor of Yapp (1990), for reasons outlined in the publication.

statement:

Oxygen isotope analysis of 21 hematite(goethite) samples (Spence, 15; Cerro Colorado, 6) was conducted at the SUERC Stable Isotope Facility (East Kilbride) via laser fluorination (e.g. Guiliani et al., 2005). For each measurement, 3–5 mg of hematite(goethite) was heated with a CO2 laser in the presence of a fluorine-based reagent (ClF3). After passing through an in-line Hg-diffusion pump, liberated oxygen was converted to CO2 using a heated rod of platinised graphite. Isotopic measurements were made using a BG Optima dual-inlet mass spectrometer. Isotopic values were calculated using the mass measurements of CO2 isotopologues and are reported as δ18O ‰ vsmow. Calibration on three secondary standards (UWG2, GP147 (international garnet standards), YP2 (internal quartz standard)) gave a standard error of 0.07 and R2=0.9999. Internal uncertainty on the isotopic measurements is <0.1 ‰ (1σ).
