Paragenetic and General Notes

In the upper parts of the first oxidation zone, including the outcrop, linarite commonly occurred in a matrix of granular cerussite, sometimes with brochantite, malachite and (less commonly) caledonite.

Linarite is commonly encountered as a partial coating on, or as near-surface inclusions in, cerussite crystals.
