Whole-rock and sulfide-mineral geochemical data for samples from volcanogenic massive sulfide deposits of the Bonnifield district, east-central Alaska
The data consist of major- and trace-element whole-rock geochemical analyses and major- and trace-element analyses of sulfide minerals determined by electron microprobe and laser ablation–inductively coupled plasma–mass spectrometry (LA-ICP-MS) techniques |
