Microspherules formed by lightning strikes

open access: yesMeteoritics &Planetary Science, Volume 61, Issue 5, Page 743-767, May 2026.
Abstract Natural microspherules are formed by high‐temperature processes and are present throughout the geologic record to the present day. We report the discovery of large numbers of microspherules recovered from a rock pavement in the Pilbara region, Western Australia.
