The zircon grains analyzed in sample 11-383c were selected from mineral concentrates using tweezers under the microscope according to criteria of clarity, similarity of crystal form, and lack of inclusions. All grains were chemically abraded using the Mattinson (2005) chemical abrasion thermal ionization mass spectrometry (CA–TIMS) technique. The selected crystals of zircon were annealed at 900 °C for 36 h prior to etching in concentrated HF acid in a pressure bomb at 200 °C for a few hours.
