Statement

Zircons were chemically abraded. The leached zircons and all total procedural blanks were spiked with mixed 205Pb–233U–235U (ET535) EARTHTIME tracer solution and dissolved. Isotope ratios were measured on a Thermo-Electron Triton TIMS at BGS (Keyworth). The U/Pb ratio for each analysis was determined via isotope dilution principles and the ET535 mixed 205Pb-233U-235U tracer. 238U-206Pb dates were corrected for initial 230Th disequilibrium using a Th/U[magma] value of 2.63.
