From: The response of zircon to the extreme pressures and temperatures of a lightning strike
Backscattered electron images of Zr-rich grains in the York County fulgurite. Most grains are predominantly composed of zircon and one grain (YPA-z40 in c) is entirely composed of vermicular ZrO2 on the exposed surface. See Supplementary Figs. S7–S9 for backscattered electron and cathodoluminescence images of all 91 grains documented in the fulgurite.
