From: The response of zircon to the extreme pressures and temperatures of a lightning strike
Imaging of zircon grains from soil and rock collected near the fulgurite but not affected by the lightning strike. These grains act as a control, showing how zircon in the fulgurite may have appeared if not subjected to the extreme conditions of the lightning strike. (a,b) and (e,f) from soil sample YPAcon3; (c,d) from rock sample YPAcon1. All images of zircon in samples YPAcon1 and YPAcon3 are available in Supplementary Figs. S1–S6.
