Geochemistry and High-Resolution Backscattered Electron Imaging of Meteor Crater Impact Melts Geochemistry and High-Resolution Backscattered Electron Imaging of Meteor Crater Impact Melts
Utilizing the USGS Meteor Crater Sample Collection, we sampled impact melt particles for geochemical and textural characterization using a scanning electron microscope and electron microprobe. Samples were collected from a range of different depths and distances from the crater rim, all within the proximal ejecta blanket. By using the Meteor Crater Sample Collection, in which all samples...
