Name:
Named after David Shannon, prolific Arizona mineral collector and dealer, and former holder of the Midnight Owl pegmatite mine claim.


A lead oxycarbonate that can form naturally under highly oxidising conditions, but also from heating cerussite (e.g., during fire-setting methods used in ore extraction underground; during mine fires).
