All data were generated by the authors of this report at USGS' laboratories in Menlo Park (CA), and at the Stanford Synchrotron Radiation Lightsource (Menlo Park, CA) except for the bulk, multi-element compositional data produced by chemical digestion of samples followed by analysis using inductively-coupled plasma optical emission spectrometry or inductively-coupled plasma mass spectrometry. Those data were generated by AGAT Laboratories under contract to the USGS at its facility at 5623 McAdam Road, Mississauga, Ontario, Canada L4Z 1N9.
