Common. Occurs in all three oxidation zones.
- 1st Oxidation Zone
- 2nd Oxidation Zone
- 3rd Oxidation Zone
Very large crystals to 500 mm on a face have been reported (Key, 1996).
Paragenetic and General Notes
Anglesite is a common secondary mineral, important in lower pH parageneses and almost always closely associated with galena. It occurs most commonly as sharp, angular, diamond-shaped crystals, as thick tabular (blocky) crystals, or as thin tabular crystals, but many forms and habits have been encountered (Key, 1996).
Anglesite is a key mineral of Keller's (1977) "Type II" paragenesis (i.e. minerals forming at a lower pH range). Commonly as the only secondary mineral on, or in cavities in, galena-rich massive sulphide ores. Keller (op.cit.) identified two distinct parageneses with anglesite:
(1) Primary sulphide >> beudantite >> carminite >> anglesite >> gartrellite.
(2) Primary sulphide >> scorodite >> arsentsumebite >> anglesite >> brochantite >> cerussite (ps. after anglesite).
Anglesite has been reported to form pseudomorphs after schultenite (rare; Spencer and Mountain, 1926).
The following minerals have been reported to form pseudomorphs after anglesite: arsentsumebite (rare); cerussite (common).
