Abstract:

This spreadsheet contains (U-Th-Sm)/He data for 73 hematite samples from the supergene profile of the Spence porphyry copper deposit in the Central Andes. These data are discussed in the G-cubed publication titled 'A rusty record of weathering and groundwater movement in the hyperarid Central Andes' (Shaw et al., 2021). Spence porphyry copper deposit Drill hole SPD0324, UTM WGS1984 19S, E 474975.22, N 7481100.39 Drill hole SPD 1848, UTM WGS1984 19S, E 474998.29, N 7481399.87 Drill hole SPD 0402, UTM WGS1984 19S, E 473969.87, N 7479755.01

statement:

(U-Th-Sm)/He dating was done at Caltech, using the single aliquot method (Farley, 2002; House et al., 2000). Hematite fragments were loaded into Pt tubes and degassed by incremental heating with a Nd-YAG laser to >1000⁰ C. He extraction conducted under high pO2 (100 torr), buffering the hematite-magnetite transition to >1200° C (Hofmann et al., 2020). Isotope-dilution measurements of 4He were made with an enriched 3He spike, using a Pfeiffer Vacuum quadrupole mass spectrometer. U, Th and Sm were measured on the same aliquots using an Agilent 8800 triple-quadrupole ICP-MS (e.g. Hofmann et al., 2017). (U-Th-Sm)/He ages were calculated according to Farley (2002). Since aliquots were taken from structures much larger than the typical alpha-particle stopping distance in hematite of 13-16 µm (Ketcham et al., 2011), no correction for alpha-ejection or -implantation was applied.
