Fig. 3.From: A novel particle source based on electrospray charging for dust accelerators and its significance for cosmic dust studiesBackscattered electron image of the allocated sample of ordinary chondrite ALHA 79045. Sample mass was 9 mg. Energy dispersive spectroscopy revealed at least four phases in the sample. The brightest areas are rich in Fe and S, the medium-bright areas are rich in Fe and O, the medium-dark areas are rich in Fe, Mg, Si, and O, and the dark areas are C-rich.Back to article page
