Cerussite after Phosgenite - Sold


Tarnowskie Góry is a historic silver mining area. The mines carried a lot of oxidized lead, mainly in the form of cerussite. Cerussite is simple lead carbonate while phosgenite is a combination lead carbonate chloride. Cold water, especially meteoric waters carrying dissolved carbon dioxide, free chlorine from phosgenite and leave behind cerussite. These unusual pseudomorphs have been known since the nineteenth century, and this specimen likely dates to that time period.
