Mereheadite - Reserved

Mereheadite is a complex lead oxide hydroxide chloride borate carbonate. Welch et al. (1998) named the mineral after its type locality at the Merehead quarry. Krivovichev et al. (2009) refined the crystal structure and found borate and carbonate anions present. Mereheadite forms orange scales, forming a patch 9 mm across in mendipite. Hydrocerussite and crednerite are also present on this specimen.
