Data Quality
Supplementary Table 1: For the Aluto samples sanidine separates were loaded into aluminium disks and irradiated for 30min in the Cd-lined facility at the TRIGA Reactor, Oregon State University. Following a ~2-month cooling period the sanidine seperates were analysed at the NERC Argon Isotope Facility, Scottish Universities Environmental Research Centre (SUERC) in a MAP-215 mass spectrometer, with a measured sensitivity of 1.13 × 10-13mol V-1. Supplementary Table 2: For the Corbetti samples sanidine crystal separates were irradiated for 1 h in the central thimble of the U.S. Geological Survey TRIGA reactor in Denver, Colorado. 40Ar/39Ar geochronology was performed at USGS Menlo Park.
