Reidite

Comments: Scanning electron microscope photomicrograph of the surface of an etched shocked zircon with a skeletal crystalline phase that may be reidite. X-ray diffraction data indicate that this zircon contains minor amounts of reidite. (AmMin 87:563).
Location: Found in an upper Eocene impact ejecta layer in marine sediments on the upper continental slope off New Jersey and on Barbados. Scale: See Image.
