    • Geochemistry and High-Resolution Backscattered Electron Imaging of Meteor Crater Impact Melts

    Metadata Updated: July 20, 2024

    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 have known geospatial locations, we are able to quantify the spatial relationship and variability between mixing of melted target rocks and the Canyon Diablo meteorite. Presented here are high-resolution backscattered electron images of all analyzed impact melt particles, and geochemical data for glass and individual mineral phases within the particles.
