Ταξινομικός αριθμός:
D11 (11)
Συστηματική ταξινόμηση:
Oxides
Μεταφρασμένος τίτλος:
Pyrolusite
Προέλευση:
Langeberg/Saxony, Germany
Περιβάλλον γένεσης:
A common Mn mineral, although difficult to distinguish from similar Mn minerals, pyrolusite forms under oxidizing conditions and high pH. Mainly a mineral of lacustrine, shallow marine, and bog deposits, it is also found in the oxidized zones of manganiferous ore deposits and as deposits formed by circulating meteoric water. Both colloidal processes and bacterial action are important in its formation.
