About Cerusita
A lead carbonate that commonly forms prismatic, tabular or acicular crystals. It is usually translucent, with vitreous lustre and colours ranging from colourless to grey. It is common in the oxidation zones of lead deposits.
About the locality
The Filón Sur at Tharsis, noted for its historic mining, produced excellent cerussites in cavities rich in iron oxides. At present, the extraction of aesthetic specimens is difficult due to the degradation of the deposit.
